White to move. How should White proceed?
Nxg6, and since hxg6 loses to QxQ, it should win at least the exchange and a pawn
nf7
N-KN6+ and then RxR gives white a pawn and at least the exchange.
Nf7 does not work because black moves Kg7 and is better. the knight attacks nothing.
Nxg6 takes a pawn and attacks a rook. if black plays Kg7 then the knight can take a rook. This is the better move.
1, Nxg6 Kg7
2, Nxf8 Qxc3
3. bxc3
black is lost.
1st solution : Ng6 hg6 Qf6+ Rf6 Re8 wins
2nd solution : Ng6 Kg7 Nf8 Rf8 Re7 Rf7 Rf7 Kf7 Qf6 Kf6 Re1 (white should win)
3rd solution : Ng6 Kg8 loses to Qf6 Rf6 Re8+
Nf7 is weaker compared to Ng6
because after Nf7 Kg7. black still can survive.
White has a positional advantage over black that can result in a winning exchange even if black makes the best out of his dire situation. It goes like this:
Nxg6+ Kg7
Nxf8 Rxf8
White looses a knight but gains a rook thus winning the exchange.
1. Nxg6+ Kg7 (otherwise mate or heavy loss)
2. Nxf8 Rxf8 (otherwise losing the rook)
I would like to go beyond this position
3. Re7+ Kg8
4. Qxf6 Rxf6
5. Re8+ Rf8 (to save bishop)
6. Rxf8 Kxf8
7. Re1
3. Re7+ Rf7
4. Qxf6 Kxf6
5. Rxf7 Kxf7
6. Re1
Even with a few forced variation the same position can be achieved. The advantage of this position is black’s king cannot come and attack white’s passed pawn. Black’s bishop is no use for the same. White needs to carefully bring the king towards center. The only possible counter-threat could be on queen-side 3-pawn to 2-pawn. Since white’s pawn are located at dark squares and black has light bishop, it has to sacrifice the pawn if at all to proceed. Even if it sacrifices, it can create a pawn on a/c file.
In the end I do not see even slightest counter-attack from black. It is a clear win for white.
