The idea is to put pressure on the d-file, potentially attack the bishop on d6, and remove the queen from possible trades on the e-file.18.dxe6This simplification is also possible, giving White a small edge. But the game would continue in a completely opposite manner to the actual game.Qxe619.Qxe6Rxe620.Bxf6Rxf621.Rfd1⩲18....e519.Re1g520.Nxg5!!...One of the most beloved sacrifices for all players and a very strong one in this position. The engine gives it thumbs up as well.20....hxg521.Bxg5e422.Rh3Qe523.f4!...The only good choice here. White defends the bishop and attacks Black's queen.23.Ree3??Qxg524.Reg3Bxg325.Rxg3Qxg326.hxg3-+and White gave away too much material.23.Bxf6?Simplifications help the defending side. After this trade, White will not have enough attacking force to create any danger.Qxf624.Qh5Qg725.Ree3Re5-+23....Qf524.g4...Not a preferred move by the engine, but a still a move that puts some pressure on Black.24.Ree3!?A preferable choice by the engine: making a rook lift and bring her into the attack via the g3-square.Kf8!Running away from the danger.25.Reg3e3!Black is hoping for trades while getting the pawn closer to the promotion square.(25...Bxf4?26.Qf1!+−)26.Rh8+Kg727.Bxf6+Kxf628.Rh6+Ke729.Rxe3+Kd8(29...Kd730.Qa4+!!+−)30.Rxd6+Kc731.Rxe8Rxe832.Rh6Qxf433.Rh3⩲24....Qxg4+25.Rg3Qxd126.Bxf6+Kh726...Kf8??This is putting the king into mating nets.27.Rxd1Bxf428.Rh3+−And a checkmate is inevitable in three moves.27.Rxd1e3??This move gave Zatonskih a chance to finish in a style and aim at the best game prize of the tournament (if there is such a prize).28.Rf3?...Not this way. Black is out of trouble after the next move.28.f5!!Brilliancy alert!Bxg329.hxg3White does not care that she is an Exchange down, or that Black's e-pawn is dangerously close to the promotion square. It is the black king that is in trouble. Notice the mating net that only needs a rook on the h-file to finish it off.e230.Re1Kg8(30...Rg831.Kg2Rg732.d6White can choose from a million of ways to win this position.)31.Kg2!Re432.Rh1+−28....Kg629.Bc3Kf530.Be5??...30.Rd3!?It is suddenly Black who starts applying the pressure.

Given the strong structure and the passed pawn on e5, this position would not be easy to win for Black.31....Bxe532.fxe5Rxe5-+Game over.
