Canada's round 8 opponents at the Olympiad: how Turkey and Spain play

Short answer

In round 8 of the 46th Chess Olympiad, on 24 September 2026, Canada meet Turkey in the open section, on table 11, and Spain in the women's section, on table 14. Drawing on 1,036 classical games broadcast on Lichess over the past three years, this article examines the opening repertoire of both squads, the specific variations in which opponents score below their historical averages, the phases in which the engine identifies significant inaccuracies, and the supplementary insights provided by online games — accompanied throughout by sample sizes to ensure statistical rigor.

Event: 46th FIDE Chess Olympiad

How this was compiled: Researched on 23 September 2026, with round 7 finished and round 8 still to be played: it starts on 24 September at 3 pm Samarkand time (10:00 UTC). The pairings were checked on chess-results. The official PGN with each team's line-up only comes out when the round starts, so this dossier covers both opponents' full squads rather than just the four boards. The repertoire uses the 1,036 classical over-the-board games from the last three years broadcast on Lichess and linked to each player by FIDE ID: 485 from the Turkish squad and 551 from the Spanish. The error profile measures each player's 12 most recent games with Stockfish 19 at depth 16. Every move quoted in the text was re-measured at depth 24, with a dedicated search and a clean hash, and endgames of up to seven pieces were checked in the Lichess tablebase. The blitz and rapid repertoire comes from verified Chess.com accounts, over a 90-day window.

The essentials in a few lines

• In round 8, on 24 September 2026, Canada face Turkey in the open section (table 11) and Spain in the women's section (table 14). All three teams enter with 10 match points. On initial tournament seeding, both opponents hold theoretical favouritism: Turkey are seeded 14th against Canada's 41st, and Spain are seeded 19th against Canada's 38th. As the official line-up appears in the PGN only at the start of the round, the dossier covers all ten players across both squads.
• Yagiz Kaan Erdogmus, Turkey's top board at 2716 at age 15, has scored 5 points from 6 games undefeated in Samarkand, including draws with Nodirbek Abdusattorov and Vincent Keymer. In the sample, facing elite opposition, he achieved 65.7% in 35 games with White. With Black, he falls to 46.4% in 14 games against 1.d4, a high-confidence finding.
• With White, Ediz Gurel opted for 1.e4 in 40 of 41 games, with the classical reply 1...e5 holding him to 60.9% across 23 games. Vahap Sanal scores 35.7% in 7 games against the Slav Defence and contests the longest games in the fixture, with a median of 97 plies. In round 7, against Germany, he was defeated by Rasmus Svane following 46.Ba5 in a bishop endgame the engine assessed at −0.88 prior to the move.
• Sabrina Vega Gutierrez opened 1.e4 in all 66 of her White games, falling to 36.7% in 15 instances when the Sicilian proceeded with 2...Nc6 — a high-confidence variation. Ines Prado Acebo recorded 31.2% in 16 White games following 1.d4 Nf6 2.c4 e6, also with high confidence. Monica Calzetta Ruiz scored 22.2% in 9 games with 1.e4 c5 2.Nf3 g6.
• Spain's women's team enter the round following consecutive draws, having let slip decisive advantages in round 6. Against Turkmenistan, Marta Garcia Martin held a +9.96 evaluation on move 41 and played 41.Qxg4, which dedicated re-measurement reduces to −0.15, resulting in a draw. In the same match, Calzetta Ruiz held equality against Mahri Agamuradova (1939) before playing 38...Qxf1+, which took the evaluation to −6.55 and resulted in defeat, sealing a 2–2 draw.

The round 8 picture

Canada reach the eighth round after defeating New Zealand 2.5–1.5 in the open section and drawing 2–2 with Hungary in the women's event. In both fixtures, the teams enter strictly level on 10 match points. In the open, Canada and Turkey are also level on individual game points, at 18.5 each. In the women's competition, Canada hold a slight edge on tiebreak criteria, with 20 game points to Spain's 17.

According to initial tournament seedings, Canada are the challengers in both matches: in the open they are seeded 41st against Turkey's 14th; in the women's section, 38th against Spain's 19th. Turkey have suffered two match defeats in the competition: against Uzbekistan (1.5–2.5) in round 4 and against Germany (1–3) in round 7. Canada have likewise lost twice: against Serbia in round 3 and against Spain (0.5–3.5) in round 5 — though that was Spain's open squad. The Spanish women's team has conceded defeat only to the United States (0.5–3.5) in round 4, arriving from consecutive draws against Turkmenistan and Belarus.

The sample sizes recorded in the table below provide the empirical foundation for evaluating each tactical deduction, with both squads extensively represented. The Turkish dataset totals 485 classical games, while the Spanish sample contains 551. Sabrina Vega Gutierrez accounts for the largest individual sample in either match (132 games), followed by Isik Can and Monica Calzetta Ruiz with 116 each. Yagiz Kaan Erdogmus has the smallest individual volume (69 games), but his are the only games contested entirely against elite opposition: his opponents average approximately 2690, matching his rating level in the sample.

In round 7, Turkey deployed Erdogmus, Gurel, Isik Can, and Sanal, resting Emre Can; Spain fielded Garcia Martin, Vega Gutierrez, Matnadze Bujiashvili, and Calzetta Ruiz, resting Prado Acebo. Erdogmus has been the central figure of Turkey's campaign, scoring 5 points from 6 games; Gurel has accumulated 4 points from 6, with both standing as the team's only undefeated players. For Spain, Matnadze Bujiashvili has posted 5.5 points from 7 games, losing only to Jan Jodilyn Fronda of the Philippines. Because squad rotation is standard protocol in Olympiad competition, the dossier examines all five members of each squad.

Turkey: young talent on top boards and vulnerabilities with Black

Yagiz Kaan Erdogmus is Turkey's top board by rating at 2716 and the youngest player in the lineup (born in 2011). In the analysed sample, he faced opposition averaging close to 2690, conferring solid statistical reliability on his numbers. With White, he scored 65.7% in 35 games (13 wins, 20 draws, and 2 defeats), selecting 1.e4 in 29 games: against 1...e5, he achieves 69.0% in 21 games; against the Sicilian with 2.Nf3, his score drops to 41.7% in 6 games (5 draws and one loss, with no wins). With Black, he maintains 52.9% in 34 games, with a distinct divergence by first move: against 1.e4 he scores 50.0% in 14 games, falling to 46.4% in 14 games against 1.d4 (one win, 11 draws, and 2 losses). In Samarkand, he remains unbeaten with 5 points from 6 games, having drawn with Black against Nodirbek Abdusattorov and Vincent Keymer.

Ediz Gurel, born in 2008, occupies the second board at 2636, displaying the most pronounced performance asymmetry in the squad. With White, he achieves an outstanding 68.3% in 41 games (16 wins, 24 draws, and one defeat); with Black, he declines to 50.0% across the same number of games. In both colours, his average opposition was rated roughly 100 points below his level. He opened with 1.e4 in 40 of his 41 White games, with 1...e5 restricting his return to 60.9% in 23 games — classified as a high-confidence finding. With Black, he scores 50.0% in 18 games against 1.e4, 44.4% in 9 against 1.d4, and 35.7% in 7 against 1.Nf3. His games have a median duration of 74 plies. In Samarkand, he has 4 points from 6 games, including a draw with White against Javokhir Sindarov (rated 2778).

Isik Can, born in 2005, holds the largest Turkish sample (116 games) and the highest percentages: 71.8% in 62 White games and 62.0% in 54 Black games. His tournament schedule accounts for a significant portion of these figures, as his opponents averaged between 115 and 140 points below him. He selected 1.e4 in 58 of his 62 White games; against the Sicilian with 2...d6, his score declines to 58.3% in 6 games. With Black, he meets 1.e4 with the Sicilian, scoring 50.0% in 6 games in the 2...e6 variation; against 1.d4 d5 2.c4, he also achieved 50.0% in 8 games. In Samarkand, he has 3 points from 6 games, suffering defeat in round 7 against Frederik Svane.

Vahap Sanal, born in 1998, contests the longest games in the fixture: the median duration reaches 97 plies, with 72% extending past move 40. He scores 67.0% in 53 games with White and 59.3% in 54 with Black, against opponents averaging 95 to 120 points below him. Playing Black, his performance varies notably by opening: against 1.e4 he scores 61.3% in 31 games, falling to 45.5% in 11 games in the Ruy Lopez; against 1.d4 he records 52.8% in 18 games, with all 7 games after 1.d4 d5 2.c4 featuring the Slav Defence, where he scored a modest 35.7%. In Samarkand, he has 2.5 points from 5 games, losing in rounds 4 and 7 to Nodirbek Yakubboev and Rasmus Svane.

Emre Can, born in 1990, is the most experienced player on the roster at 2534, having rested in round 7. He scores 66.1% in 56 White games and 62.7% in 55 Black games against opponents averaging between 120 and 135 points below him. With Black, against 1.d4, he scores 56.7% in 15 games, with the Queen's Gambit Declined (1.d4 d5 2.c4 e6) yielding 50.0% in 7 games. Against 1.e4 he plays the Sicilian, recording 50.0% in 6 games after 2.Nf3 Nc6 (with six draws). In Samarkand, he remains undefeated with 3.5 points from 5 games.

Spain: steady International Masters and fourth-board fluctuations

Sabrina Vega Gutierrez is Spain's top player by rating at 2363, with 132 games in the sample. With White, she scores 62.1% in 66 games against opponents averaging approximately 100 points below her, opening with 1.e4 in all 66 encounters. Against 1...e5, she achieves an imposing 86.4% in 11 games. Against the Sicilian with 2.Nf3, faced in 37 games, her score drops to 55.4%, falling sharply to 36.7% across 15 games when Black replies with 2...Nc6 (4 wins, 3 draws, and 8 losses) — designated as a high-confidence finding by the dossier. With Black, she scores 59.1% in 66 games, meeting 1.e4 with the Sicilian in all 34 games (60.3%) and scoring 41.7% in 6 games against 1.d4 d5 2.c4 e6 3.Nf3. In Samarkand, she has 4 points from 7 rounds, suffering defeats to Maftuna Bobomurodova of Uzbekistan (2030) and Alice Lee of the USA.

Marta Garcia Martin, born in 2000, has played all seven rounds on top board for Spain. She scores 61.7% in 60 games with White and 61.5% in 52 with Black. The primary technical discrepancy appears in her Black repertoire: against 1.e4 she achieves an exceptional 75.0% in 24 games (and 86.7% in 15 in the Sicilian); against 1.d4, however, her score declines to 46.9% in 16 games (3 wins, 9 draws, and 4 defeats). Following 1.d4 Nf6 2.c4 e6, she recorded 40.0% in 5 games. With White, she alternates between 1.e4 (70.4% in 27), 1.d4 (52.9% in 17), and 1.c4 (55.0% in 10). In Samarkand, she has 4 points from 7 games, losing to Carissa Yip of the USA and Aliaksandra Tarasenka of Belarus in round 7.

Ann Matnadze Bujiashvili, born in 1983, exhibits the highest percentages in the squad: 68.9% in 53 White games and 62.7% in 51 Black games. It must be noted that she faced opposition averaging roughly 150 points below her, the widest gap in the fixture. With White, she opens with 1.d4 in 33 games (72.7%) and 1.Nf3 in 18 (61.1%). With Black, she scores 66.7% in 27 games against 1.e4, managing 50.0% in 6 games in the Philidor Defence (1.e4 e5 2.Nf3 d6) and 58.3% in 18 games against 1.d4. In Samarkand, she has 5.5 points from 7 games, drawing with Irina Krush of the USA.

The final two players on the roster faced opponents of comparable rating and remain near 50%. Ines Prado Acebo scores 49.0% in 49 games with White and 51.3% in 38 with Black. She opens 1.d4 in 33 games; after 1.d4 Nf6 2.c4 e6, she recorded 31.2% in 16 games (one win, 8 draws, and 7 losses), a high-confidence variation. With Black, she scores 71.4% in 14 games against 1.d4 and 47.1% in 17 against 1.e4. She contested rounds 1, 2, and 5, scoring 2.5 points. Monica Calzetta Ruiz, born in 1972, scores 51.7% in 59 White games (opening 1.e4 in 57) and 52.6% in 57 Black games. Facing 1.e4 c5 2.Nf3 g6, her score fell to 22.2% in 9 games, with 6 losses. In Samarkand, she has 1 point from 4 games.

Where the engine finds the errors

The table below outlines the average evaluation loss per move in each phase of play, alongside the number of moves analysed. In the opening, all ten competitors remain tightly clustered between 4 and 13 centipawns. In the middlegame, the squads diverge: Turkey range from 14 (Gurel) to 25 (Isik Can), whereas Spain span from 27 (Vega Gutierrez) to 49 (Calzetta Ruiz). In the endgame, Erdogmus achieves just 6 centipawns — the lowest figure across both fixtures —, while Isik Can records 24. For Spain, endgame figures range between 29 (Prado Acebo) and 43 (Calzetta Ruiz) — noting that Vega Gutierrez's average of 32 centipawns incorporates computational anomalies resolved by tablebase analysis, as explained below.

Vahap Sanal is the only Turkish Grandmaster with a higher loss rate in the endgame than in the middlegame (21 versus 17), with his two costliest moves occurring in that phase. In round 7, against Germany, he held a manageable disadvantage of −0.88 in a bishop endgame against Rasmus Svane before playing 46.Ba5, after which dedicated re-measurement at depth 24 indicated −4.73, leading to defeat. In the Turkish Super League in August, he held a +5.21 advantage in a rook endgame against Nijat Abasov (2588) before playing 44.Rd2, an inaccuracy that levelled the evaluation to −0.01 and resulted in a draw. Emre Can surrendered a forced victory in similar fashion: in round 2 against Niaz Murshed of Bangladesh (2342), the tablebase confirmed a solitary winning path with 60.Rb6; he played 60.Kg5 and drew.

Isik Can and Emre Can faced each other in the Turkish Super League in August, committing mutual errors in the same sequence of moves. In an equal position, Isik Can played 32.Qxe6, evaluated by the engine at −6.63; rather than replying with the decisive 32...Qc3, Emre Can responded with 32...Re4+, returning the evaluation to 0.00 and leading to a draw. Ediz Gurel displays the most consistent middlegame on the squad (14 centipawns) and rescued a compromised position against Sina Movahed (2595) in the same league: after 31...Bf6, dedicated analysis indicated a critical deficit of −5.73, before the young master held a draw after 199 plies.

In the Spanish team, the sixth round concentrated the most decisive errors. Against Turkmenistan, Marta Garcia Martin reversed an early disadvantage and stood at +9.96 on move 41, where 41.Ne8+ preserved a forced win; playing 41.Qxg4, the evaluation dropped to −0.15, resulting in a draw. In the same match, Monica Calzetta Ruiz held equality against Mahri Agamuradova (1939) before playing 38...Qxf1+, which took the evaluation to −6.55 and resulted in defeat, concluding the match at 2–2. In round 2, Sabrina Vega Gutierrez held equality against Maftuna Bobomurodova before playing 47.Nexd4, dropping to −4.92 and defeat. In the same fixture, Ines Prado Acebo led with +5.20 against Barchinoy Shokirjonova before 82.h7 reduced her edge to +0.13, drawing after 170 plies.

Ann Matnadze Bujiashvili secured victory in round 7 after letting slip a winning endgame. Against Veranika Abramkina of Belarus, the tablebase showed forced wins with 75...Rg7 or 75...Rg2+; Matnadze played 75...Rg5, allowing a theoretical draw under best play. Abramkina failed to locate the drawing resource, and Matnadze prevailed on move 88. In round 6, she led with +4.58 against Jahan Rejepova before playing 51.Kf2, which reduced her margin to +0.27 before winning later.

Elevated figures do not always denote genuine strategic errors, as tablebase verification clarifies two such instances. At depth 16, moves 62.Kxh6 and 63.h5 by Vega Gutierrez against Bobomurodova appear with severe penalties; the tablebase confirms that the position was already lost by any continuation. The same dynamic applies to Erdogmus: his move 58.Rb6+ against Sebastian Bogner in round 6 is flagged as an error in shallow searches, but re-measurement confirms forced checkmate in 10 moves. In both cases, shallow analysis misread settled endgames. Uncapped blunder totals are consequently excluded from the table, confirming that Vega Gutierrez's endgame average of 32 centipawns is influenced by such computational distortions.

What the online accounts show, and what they do not

This section serves a distinct analytical purpose from the preceding examination and is consequently presented in its own right. Repertoires in rapid and blitz controls are naturally more fluid and experimental than in classical chess, since decisions executed under three minutes differ fundamentally from preparation designed for long tournament games. These records illustrate an athlete's practical familiarity with specific structures and identify areas of discomfort, without providing dogmatic forecasts for the upcoming round.

The account mirman90, belonging to Emre Can, is the only profile in the fixture with variations meeting medium or high confidence thresholds. He played 300 blitz games in the period, scoring 58.3% in 151 White games and 55.0% in 149 Black games. With Black, against the King's Indian Defence (1.d4 Nf6 2.c4 g6), he managed only 39.3% in 14 games (5 wins, one draw, and 8 losses). With White, after 1.d4 Nf6 2.c4 e6, he scored 45.8% in 12 games, recording 45.5% in 11 games in the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5) — with the Ruy Lopez also representing the line where Sanal encounters difficulties playing Black in classical chess. These data do not guarantee that Emre Can will play the King's Indian Defence over the board; they reveal, however, that the variation has proven fragile in his recent practice.

The account gurelediz, belonging to Ediz Gurel, contains 300 games in the period, requiring precise technical qualification: 222 were contested in bullet controls (one minute per player) and 78 in blitz. Under hyper-bullet controls, opening choices reflect reflex rather than theoretical preparation. He scores 71.3% with White and 65.3% with Black, with his only medium-confidence variation being 1.d4 Nf6 2.Nf3 d5, yielding 58.3% in 6 White games — precisely the colour and initial move he virtually never employs in classical chess.

Yagiz Kaan Erdogmus contested 75 games under legendisback1 (39 bullet and 36 blitz), with no statistically established variations. Isik Can has 59 games under isikcan05 (41 blitz and 18 bullet), likewise without conclusive lines. Vahap Sanal recorded 50 blitz games under santoblue, scoring 36.0% in 25 Black games (and 20.0% in 10 against 1.d4, aligning with his classical record, though remaining an initial indicator). For Spain, Marta Garcia Martin, Sabrina Vega Gutierrez, and Monica Calzetta Ruiz hold verified accounts, but recorded no games during the window. Ann Matnadze Bujiashvili played a single game, and Ines Prado Acebo has no confirmed account.

What to watch in round 8

Strategic planning in the open match depends upon Turkey's confirmed board order, with the dossier providing tactical recommendations for all five players. With White, facing Erdogmus with 1.d4 represents the most substantiated choice (14 games, high confidence, and opposition of equal rating). Against Gurel, 1.Nf3 yields 35.7% in 7 games and 1.d4 leads to 44.4% in 9. Against Sanal, 1.d4 challenges his 52.8% in 18 games, with 2.c4 capable of steering into the Slav Defence; against Emre Can, 1.d4 leads to 56.7% in 15 games. When playing Black, Turkey score heavily against virtually all setups, with the exceptions of Erdogmus (who drops to 41.7% in 6 games against the Sicilian with 2.Nf3) and Gurel (who scores 60.9% in 23 games against 1...e5, his lowest White score).

In the women's match, strategic considerations depend on colour. Playing Black against Vega Gutierrez, the Sicilian with 2...Nc6 leads to the line where her score falls to 36.7% in 15 games; against Prado Acebo, 1...Nf6 followed by 2...e6 targets her 31.2% in 16 games. Playing White, 1.d4 tests Garcia Martin's 46.9% across 16 games; against Calzetta Ruiz, 1.e4 can challenge the 2...g6 Sicilian, where she scored 22.2% in 9 games. Against Matnadze Bujiashvili, no defensive system reduces her return below 50%. These findings rest upon samples of 9 to 16 games — valuable parameters to inform immediate preparation, without offering dogmatic guarantees.

When the round commences and the official PGN confirms the board pairings, the dossier files connected to this article will automatically display the four boards and the live games. Until then, the assessment presented here covers both squads in full: ten players analysed, 1,036 games examined, an undefeated Turkish top board in Samarkand, and a Spanish team that let slip match victory in round 6 in two critical moves.
