The most tenacious.
If the sacrifice is accepted, then after 21.gxh3 Rad8 22.f4 Rxd4 23.fxe5 Qxe5 24.Re2 Re6, followed by ...Rg6+ and ...Ne6, all Black’s pieces are attacking, and this attack assumes a decisive character.

As a result of the tactical operation, Black has won a pawn without any compensation. In addition, the white king is weak.
Unfortunately, Black lost a significant part of his advantage in time-trouble, by choosing the prophylactic 29...Kh7. Later, after mutual time-trouble mistakes, White missed a chance to win, and the game was eventually drawn.

The battle is mainly taking place on the light squares. At the same time, the black king finds himself in an unpleasant opposition on the diagonal, and there are also checks threatened on e7 or h6. Checks against the white king get nowhere, and so a strong move is...
removing all threats and freeing the Be6.
The end of the game probably took place amidst time-trouble, and there followed instead 38...Be5+? 39.Kg2 (White wins with 39.Kh4!! Qe8 40.Bc6) 39...Bxd5+ 40.Rxd5 Qb7? (with mutually correct play, after 40...Qe6 41.Rxe5 Qxe5 42.Nxh6+ Kg7 43.Nf5+ Kh8 44.Qf2 Qd5+ 45.Kh2 Rf7 46.Qf4 Rh7+ 47.Kg3 Ne4+ 48.Kg2 Ng5+ 49.Kg3, a draw could result) 41.Ne3, and White won.

Training position Konstantin Sakaev White to move
The black king is in an exceptionally dangerous position, under the fire of the white pieces. The white knight attacks numerous important squares, his queen is ready to penetrate to the eighth rank, he has pressure on the f-file, and the epawn can advance. However, immediate checks or direct attacks lead to nothing. Unfortunately, in the event of the bishop taking the knight on f6, the black queen recaptures with check. Reasoning along these lines, one can appreciate that the white king is poorly placed on b2, and there is a square where he would not be subject to checks:
White’s attack comes to a dead end after 35.Ne6+ Kg8 36.Qb8+ Qe8.
Another false trail is the tempting 35.Re6 Qf5 36.Qxf5 Nxf5 37.Bxf6, because of 37...h6!.
All of Black’s pieces are tied to the defence of something or other, and the only move that does not lose at once is to move out of one pin into another.
