gurelediz vs Firouzja2003: game review

33.Qd7 is a mistake: White's winning chances go from 45% to 29%.

• Black answers 33…Qxd7, which takes the queen on d7.
• Better was 33.Rd3 (−0.51).

Better: 33.Rd3 prepares Ba1 and Bc3. After 33…Qb8 34.Ba1 Rb4 35.Bc3 Nxd4 36.Qc5 Rxb5 37.axb5 Qxb5 38.Qxb5 Nxb5 39.Be5, the queens come off (−0.51).

35.Be2 misses 35.Qc7, which wins material. White's winning chances go from 27% to 9%.

• Black answers 35…Qxf4, which takes the pawn on f4.
• After Qxf4, Black wins 1 point of material within 2 moves.
• Better was 35.Qc7 (−2.72): adds a decisive attacker on the a5 pawn: 2 attackers against 1 defender.

Better: 35.Qc7 adds pressure on the a5 pawn and protects the f4 pawn. After 35…Qg4+ 36.Kf1 Ra7 37.Qxa7 Rxc3 38.Ke1, White comes out two pawns up (−2.72).

• Both sides followed opening theory up to 11.Rc1: 21 moves in all, 11 by White and 10 by Black.
• Theory runs out after 11.Rc1: too few games between strong players reached this position to go further.
