Black knight on f4 appeared earlier, too. But now it is not tolerated.
24.Bxf4! exf4 25.Nf5
In case of 25…g6 26.N5h4 Bg7 27.e5 dxe5 28.Nxe5 the idea of piece sac on g6 is very dangerous for Black. For example, 28…c5 29.Bxg6 fxg6 30.Qxg6 и Nh4-f5.
25…bxa4!
A very interesting, not obvious decision.
26.bxa4
26.Rxa4 seemed natural, but then Black could get a counter play by 26…c5 27.d5 g6 28.N5h4 Rc7! transferring the rook to e7. Then possible was 29.Rd1 (29.Nd2 Nxd5!) 29…Qd8! and on 30.Nd2 he planned 30…Nxd5.
26…c5 27.e5! [not fruitful is 27.d5 Nd7] 27…dxe5 28.dxe5 Nd7?
Losing the course. Good or bad, he should have fought for space by 28…c4!, for example, 29.Bf1 Nd7 30.Rab1 Qa7, and in comparison to the game Black has no problem with king’s safety.
29.Rab1 Qa8 30.N5h4!
Now White’s attack on the white squares is very strong.
30…Rc6
It was possible to balance on the edge by 30…Bd5.
31.Be4
Better is 31.Rbd1! , but the actual game is not bad too.
31…Rb6 32.Bh7+ Kh8 33.Rxb6 Nxb6

34.e6!
This move is strong first of all because of its influence on opponent’s psychic. 34…Bxf3
Player without nerves would reply 34…Bd5! , and probably would have saved it. 35.Nxf3 g6
There are a lot of variations, but the result is the same: 35…Rxe6 36.Rxe6 fxe6 37.Ne5 Qe8 38.Bg6 Qxa4 39.Qd3 Nd5 40.Bf7 g5 (40…Ne7 41.Qd8) 41.Qg6 Bg7 42.Bxe6+-
36.Bxg6! fxg6 37.Qxg6 Qc8
It was worth a try 37…Re7 38.Ne5 Qe8, forcing the opponent to find 39.Rb1! (39.Nf7+? Rxf7 40.exf7 Qxe1+) 39…Qxg6 (39…Nd5 40.Nf7+) 40.Nxg6+ Kg7 41.Nxe7 Bxe7 42.Rxb6 and so on.
38.Ne5 Bg7
Also bad is 38…Qxe6 39.Qxe6 Rxe6 40.Nf7+ Kg7 41.Rxe6 Kxf7 42.Rxb6.
39.Nf7+ Kg8 40.Nxh6+, and Black resigned without waiting for 40…Kh8 41.Nf5 Bxc3 42.Nd6.
