The story behind the game
In their Brussels Candidates tiebreak in 1991, Ivanchuk and Yusupov create a position where material on one wing competes with a king attack on the other. Black’s pawn on e3, active queen and knight routes are the key landmarks. Study how the rook joins the attack before deciding which side’s extra material matters.
Take these ideas to your next game
- An advanced pawn can restrict defensive squares without promoting immediately.
- Before taking offered material, count the attacker’s remaining routes.
- A rook lift can be more urgent than protecting a distant rook.
- Connect threats against pieces with threats against the king.

Yusupov plays 12…e3, placing a pawn close to White’s king position. The pawn attacks d2 and f2 and helps shape the defensive squares around the king. White answers f4 in the game, changing the pawn cover. An advanced pawn is not automatically strong: its concrete influence and the pieces that can use the resulting squares are what need evaluation.
Yusupov chose 23…Nxh4 in the game; the saved analysis prefers …fxg3. The knight offer invites gxh4 and …Qxh4, changing the king’s pawn cover. White also has stronger resources than accepting immediately, including forcing knight moves. The saved candidates favour the pawn capture on g3. A memorable practical attack is not proof that its first sacrifice was the best available move.
The historical 27…Re6 prepares a rook lift, while the saved evidence prefers the direct …Rg8. In the game, Qb7 is followed by …Rg6 and White takes the rook on a8. The saved defence after the lift is stronger for White than that historical continuation. Compare direct rook activity with the extra tempo used by the lift. Learning a useful manoeuvre also means recognizing when another route is more urgent.
The move 33…Nf2 attacks the d1-rook while using the advanced pawn’s support. The queen remains active near White’s king, so the knight’s attack cannot be considered in isolation. The e3-pawn is still doing useful work long after its advance. Follow White’s alternatives and Black’s queen routes in the saved lines instead of assuming that a single threat wins the game.
Result: 0-1. The recorded score ends here; it does not imply checkmate.
