Black to move. How can Black save this game?
8/1P2k3/8/PN1K3p/7P/2b5/6p1/8 b – – 0 1
Be5 is the move.
If white doesn’t capture the bish, he can’t queen his pawn. If he does capture, then black queens the pawn and white still can’t queen the pawn without losing the queen after Qh2+. So black queens and white doesn’t.
1. .. Be5
2. Kxe5 g1=Q
3. b8 =q Qh2+
I found this to be a confusing diagram, and it took me a while to see that white’s first rank is on the bottom as normal.
Having figured that out, it seems each side can make a Q in one move, but if black (to move) Queens, White will too and will win on material.
What then can black do?
Finally I saw
1. … Be5!, preventing the white pawn from queening safely and threatening to promote his own.
Of course black can take the B with his Q, but then his K has been attracted to the wrong diagonal:
2. Kxe5, g1(Q)
3. B8(Q), Qh2+
Black thus wins the Q and the game.
1…Be5
2.Kxe5, g1=Q
3.b1=Q, Qg3+
Be5 of course. THAT one was easy.

1. .. Be5
if 2.Kxe5 g1(Q)
3.b8(Q) Qh2 wins the white Queen
Sorta easy (but Lafferty won’t get it)
Be5, then Q the pawn, then Qh2+
1. …. Be5
2. Kxe5 g1Q
3. b8Q Qg3+
in endgames with mutual queening, the side to queen first can sometimes win with a deadly skewer.
The theme is here, albeit slightly hidden.
1…Be5 wins. 2. Kxe5 g1=Q 3. b8=Q Qg3 and there’s the skewer.
… Be5, kxe5 and after both queen, blk can chk and win white’s queen.

bishop to e5, if king takes you’ve got the diagonal pin after advancing the pawn
1…. Be5 looks like a winner.
1. … Bxe5
2. Kxe5 g1D
3. b8D? Qh2+
1..Be5 wins as 2. Kxe5 g1Q and white cannot queen because of the threat of Qh2+ winning the queen for black.
1.- Be5 seems to deserve a closer look. Black’s bishop controls b8, and after 2. Kxe5 g1Q 3. b8Q would be a desaster because of 3.- Qg3+ and White will lose his just born Queen.
1…Be5! 2.Kxe5 g1/Q! 0-1
i think, there´s a little trick, that might work here:
1. … Be5
2. Kxe5 g1Q
3. b8Q Qh2+
4. K any Qxb8
looks good to me, but i didn´t check or double-check it. greets, jan
1)… Be5
