Key moments

The Brilliant and Great moves, and the costliest mistakes, as the review explains them.

34…d3: Mistake

34…d3 is a mistake: Black's winning chances go from 36% to 25%.

  • White answers 35.Be3, which attacks the queen.
  • Better was 34…Qe6 (+1.56).

Better: 34…Qe6 prepares …Qb6 and …d3. Engine line: 35.Qd1 Qb6 36.Bf4 d3 37.Be3 Qb7 (+1.56).

35.Be3: Great

35.Be3! The only good move here: every alternative is clearly worse.

  • Attacks the queen.
  • Takes f2 away from the Black queen on b6.
  • The next best move, 35.Bd2, would drop White's winning chances from 75% to 64% (+1.51).
  • 35.Be3 threatens Bxb6, winning the queen.
  • It threatens Bxb6, winning the queen, so Black has to spend the next move on it.
  • Black answers 35…Qd6, leaving White with a king with pawns missing from its shelter.

The opening

Sicilian Defense: Nyezhmetdinov-Rossolimo Attack, Fianchetto Variation (B31)

  • Both sides followed opening theory up to 8.Ba4: 15 moves in all, 8 by White and 7 by Black.
  • Theory runs out after 8.Ba4: too few games between strong players reached this position to go further.
