1...Qxe5 2.Qxe5 dxe5 3.Bxf7+! Kxf7 4.Rxd7 with a clear edge in the endgame.

4...f6? 5.Qe3 the black king has nowhere to go.

A final detail, that produces a clearly superior endgame.

The last chance was 8...Rxe1 9.Rxe1 Be6!? – Milic.

Now the a6-pawn is doomed.

Black resigned.

Initiating an attack on b7 before Black manages to castle and connect his rooks.

1...Bc5? 2.Bxc5 Qxc5 3.Qxb7 White wins a healthy pawn.

The desired ...0-0 is just one move away; however...

6...0-0? 7.Bc5! Re8 8.Bb6 White wins material.
