Barp Holds Avramidou in 57-Move King's Indian Grind

A 57-Move Grind Ends in Stalemate

Alberto Barp held FM Anastasia Avramidou to a draw after 57 moves of grinding King's Indian Defense chess at the Grenke Chess Festival 2026 Open. The Italian IM, rated 2435, found himself under pressure for most of the middlegame after Avramidou's queenside pawn sacrifice generated serious activity, but he defended accurately enough to reach a dead-drawn king and pawn ending. Neither player will look back on this as their finest work, but in a nine-round Swiss where half-points matter, Barp's defensive resilience kept his tournament alive.

The game followed the classical 1.Nf3 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.d4 O-O structure of the King's Indian, but Avramidou chose an unusual approach with 6...Bg4, pinning the knight immediately rather than playing the more common ...e5 or ...Nbd7 setups. This bishop sortie led to an early exchange on f3, giving White the bishop pair but also handing Black a clear plan: undermine the center with ...c5 and generate queenside counterplay.

The Benko-Style Sacrifice

The game's defining moment came on moves 10-12. After Barp pushed 9.d5, locking the center, Avramidou responded with 9...c5 followed by 10...b5, offering a pawn in Benko Gambit fashion despite playing a King's Indian structure. This hybrid approach is rare but carries real venom — Black gives up material for open lines and pressure against White's queenside pawns.

Barp accepted with 11.cxb5 a6 12.bxa6 Nxa6, and suddenly the position transformed. Avramidou had two open files for her rooks, a knight heading to b4 via c5 or directly, and long-term pressure against the a2 and b3 pawns that would eventually appear. White's bishop pair looked impressive on paper, but with the center locked, those bishops needed open diagonals that didn't exist yet.

The Greek FM's recent form has been impressive — she's been racking up wins against players rated 2500+ in online events, including a second-place finish in a 3 0 Thursday tournament just a week before this game. That attacking confidence showed in her willingness to sacrifice material for activity rather than play a slow maneuvering game.

The Queens Come Off, But Not the Pressure

What followed was a careful dance where Avramidou kept finding ways to maintain pressure even as pieces came off the board. After 13.O-O Qa5 14.Qd2 Rfb8 15.Rfc1 Nb6, Black's pieces were perfectly coordinated for the queenside assault. The knight on b6 eyes c4 and a4, the queen supports the a-file, and the rooks are ready to double.

Barp tried to hold the position together with 16.b3, but this created a new target. Avramidou immediately struck with 16...c4!, breaking open the queenside structure. After 17.Rab1 Nb4, the knight landed on its ideal square, threatening to capture on a2.

The tactical sequence that followed was forced but instructive: 18.Be2 Nxa2 19.Qxa2 Qxa2 20.Nxa2 Rxa2 21.Bxc4 Nxc4 22.bxc4 Rxb1 23.Rxb1. When the smoke cleared, Black had won the exchange — rook for bishop — but White had connected passed pawns on c4 and d5. The evaluation was roughly equal, but the character of the position favored active play from both sides.

The Long Technical Phase

This is where the game became a test of patience and technique. Avramidou had the material advantage but needed to find a way to convert it against White's passed pawns. Barp, meanwhile, had to keep his pawns mobile while preventing Black's rook from becoming too active.

The position after 23...f5 was the kind that engines evaluate as dead equal but humans find deeply unpleasant to play from either side. Black's rook is active, but the pawns on c4 and d5 are genuinely dangerous. White's king is safe, but one wrong move and those pawns become worthless. Engines call it 0.00, but no one at the board felt comfortable.

Barp found 24.exf5 gxf5 25.g3, giving his king an escape route and preparing to activate his pieces. The game entered a phase where both players maneuvered carefully, neither willing to commit to a plan that might backfire. Avramidou's rook probed on the second rank with 27...Rc2, then shifted to the third rank with 29...Rc3, looking for ways to create threats.

The sequence from moves 30-38 saw Barp's king dance around the center while Avramidou's rook checked repeatedly, but neither player could make progress. 30.Ke2 Rb3 31.Rc6 Rb2+ 32.Kf3 Rb3 33.Kg2 Rd3 34.Kf1 Rb3 35.Ke2 Rb2+ 36.Kd3 Rb3+ 37.Kc2 Rb2+ 38.Kc1 Ra2 — this was practical chess, each player probing for weaknesses that didn't exist.

The Breakthrough That Wasn't

On move 41, Barp finally pushed 41.f4, fixing Black's bishop on f6 and preparing to advance his central pawns. This was the moment the position demanded — passive defense would eventually lose to Black's extra exchange, so White needed his pawns to move.

42.c5 dxc5 43.d6 Ke8 saw White's pawns surge forward, and suddenly the d-pawn looked dangerous. But Avramidou had calculated accurately: 44.Bxc5 exd6 45.Bxd6 Rxh2+ 46.Kd3 Rg2 won back material and left the position completely level.

The final phase was a textbook demonstration of why rook endings are drawn so often. After 47.Rxh7 Rxg3+ 48.Kc4 Rg7 49.Rh5 Kf7 50.Rxf5 Ke6, both players had eliminated each other's extra pawns, and the resulting position with rook, bishop, and f-pawn versus rook and bishop was a theoretical draw.

The final moves confirmed what both players likely knew: 51.Rd5 Rd7 52.f5+ Kf7 53.Kc5 Be7 54.Kc6 Rxd6+ 55.Rxd6 Bxd6 56.Kxd6 Kf6 57.Kd5 Kxf5 — a dead draw with king and pawn endings where neither side can make progress.

What This Means for Both Players

For Barp, this draw against a higher-rated opponent is a solid result. The Italian IM, playing for SF Berlin in the German Bundesliga, came into this tournament with 3 points from 5 games and needed to avoid losses against stronger opposition. Holding Avramidou, who has been in excellent form this year, keeps his tournament on track.

For Avramidou, the half-point is slightly disappointing given her material advantage in the middlegame, but the position was never winning by force. Her Benko-style sacrifice was creative and generated real pressure, but Barp's defensive technique was up to the task. The Greek FM has shown this year that she can compete with players well above her rating — her wins against 2500+ opposition in online events prove that — and this game, while not a victory, demonstrated her willingness to play for complications rather than safe draws.

The Grenke Chess Festival Open continues with Magnus Carlsen and Amin Tabatabaei meeting on the top board in round four, while Vincent Keymer faces Volodar Murzin. Those games will likely decide the tournament's trajectory, but in the middle boards where Barp and Avramidou were fighting, every half-point matters for final standings and rating implications.

The position after move 23, with Black's exchange advantage against White's connected passers, is the kind of imbalanced structure that makes for interesting wall art. We turned this one into a print at ChessFlow.

This was not a game of fireworks or sacrifices, but of careful maneuvering and accurate defense. Sometimes that's what chess is — two players respecting each other's preparation and finding the narrow path to a fair result.
