With two lines

A) 3…Qxa5 4.Nf3+ Kh1 5.f8Q e1Q+ 6.Nxe1 Qxe1+ 7.Kf3! Qd1+ 8.Kf4! Qd4+ 9.Kg5! Qe3+ 10.Kg4
10.Kh4? Qf2+ 11.Qxf2 stalemate.
10…Qg1+ 11.Kh5!
Thematic try: 11.Kh5? Qe2+! (11…Qe5+? 12.Qf5! Qxf5 13.Bxf5 13…Kg2 14.Kg4 – the black king doesn’t manage to come to the rescue of the pawn of g7)12.Bg4 Qh2+ 13.Kg5 Qd2+ 14.Кh4 Qf2+ 15.Qxf2 – stalemate If 14.Qf4, then 14…Qd8+! 15.Kh5 Qh8+ 16.Kg5 Qd8+ with perpetual check.
11…Qe1+ 12.Qf2! Qf5+ 13.Qf4! wins.
12.Bg4! Qd3+ 13.Bf3+ Kg1 14.Qc5+ wins.

B) 3…Qa3+! 4.Kxe2!
4.Nd3? Qxa5 5.f8Q e1Q+ 6.Nxe1 Qxe1+ =; 4.Kf4? Kh2! 5.Bd7 Qc1+; 4.Kd4? Qd1+! 5.Кd3 Qa4+ 6.Ke3 Qxa5 7.f8Q e1Q+ 8.Nxe1 Qxe1+ . or here 5.Kc5 Qc1+! 6.Nc4 Qg5+ 7.Kd4 Qf4+8.Kd5 Qf3+! 9.Kc5 Kf2! 10.Bg4 Qf4! 11.Bd2 Qc7+ 12.Kb(d) ~ Qb8(d8)+ 13.K~ e1Q 14.Bxe1 Kxe1 – every where draw.
4…Qxa5! 5.Nf3+!
Thematic try: 5.f8Q? Qxe5+ 6.Kf3 Qd5+! (6…Qh5+ 7.Bg4! Qxg6 8.Qc5+) 7.Kf4 Qd4+! 8.Kg5 Qe3+ 9.Kg4 Qe4+! 10.Kh5 (10.Kh4 Qe1+! 11.Kh5 Qe5+) 10…Qe5+! And here it is already impossible, as in the first option,10…Qe2+, because of 11.Bg4! (11.Kh4 Qe1+) 11…Qh2+ 12.Kg5 Qd2+ 13.Kh4! (13.Qf4? Qd8+ 14.Kh5 Qh8+) 13…Qh2+ 14.Bh3 and no stalemate after 14…Qf2+ 15.Qxf2, and there is a simple exchange by queens 15…Kxf2 and after 16.Kg5 Ke3 17.Kf5! the white king advances black in fight for the g7 point. 11.Qf5 (11.Bf5 Kf2 =) 11…Qxf5+! 12.Bxf5 Kf2! 13.Bd3 Ke3! 14.Kg5 Kd4! 15.Kf5 Kd5! 16.Bb5 Kd6 17.Bc6 Ke7 18.Ke5 Kd8 19.Ke6 Kg8 20.Ke7 Kh8 21.Ke8 Kg8 22.Bd5+ Kh8 23.Ke7 – stalemate in the top corner of a chessboard. The black king made a fantastic marathon from g1 on h8. Thematic tryes in the first and second versions of the decision traded places.

5…Kh1 6.f8Q!
6.Bg2+? Kxg2 7.f8Q Qa2+ 8.Kd3 Qf2 9.Ke4 Qe2+ 10.Kd5 Qd3+ 11.Ke5 Qe3+ 12.Kd5 Qd3+ – positional draw.
6…Qb5+ 7.Kf2! Qf1+!
7…Qc5+! 8.Kg3!Qd6+! (8…QxQ 9.Bg2#) 9.Ne5! (9.Qf4? Qxf4 10.Kxf4 stalemate) 9…Qxf8 10.Bg2+ Kg111.Nf3+ –
8.Kg3! Qxh3+!
8…Qf2+ 9.Kg4! (9.Kf4? Qg3+ 10.Ke4 Qf4+ draw) 9…Qg3+! 10.Kh5! Qxg6+ (10…Qxh3+ 11.Nh4 +-) 11.Kh4! +-.
9.Kf2(f4) Qg3+! 10.Ke3! Qxg6
After 10…Qf2+ 11.Ke4 Qc2+ 12.Kf4 Qxg6 white wins as 13.Qc5, so 13.Qa8.
11.Qd8 (b8, b4)? Qe6+ 12.Kf2 Qa2+ 13.Kg3 Qg2+ 14.Kf4 Qf2!; 11.Qc8? Qb6+; 11.Qa8? Qb6(g3) =
11…Qe6+ 12.Kf4!
It is possible to move only clockwise. 12. Kf2? Qa2 + 13.Kg3 Qg2 + 14.Kf4 g5 + =.
12…Qf6+ 13.Kg3.
Other continuations conduct to loss of time that is inadmissible in studies on the win.
13… Qg6+ 14.Kf2 Qg2+ 15.Ke3! Qg3! 16.Qc2! Qd6
16…Qb8 17.Qh7+ Kg2 18.Ne1+ – .
The only move that leads to the win. 17.Qb1 (c1)+ Kg2 18.Qc2+ (18.Qb2+? Kh3! =) Kh1 19.Qb2 or 17.Qe4 Qg3 18.Qc2 – it is loss of time.
17…Qc5+ 18.Ke2
The loss of time led 18.Kf4 Qd6+ 19.Ke3 (or 19. Ne5 Qc5 20.Nf3 Qd6 +) 19…Qc5 + 20.Ke2 and then – as in the solution.
18…Kg2 19.Qxg7+ Kh3 20.Qh6(h7,h8)+ 21.Kg4 Qh4+ -.

19.Kf2! Qс5+ 20.Kg3 Qc7(d6)+ 21. Ne5! wins.
