White wins with 1. Kc6.
easy i believe…
Kc6 g3 Kc6 Kb8
Kc7 g2 b6 g3
b6 g1=Q b7 g2
b7+ Ka7 a6 g1=Q
b8=Q+ Ka6 a7+ Kxa7
Qb6# b8=Q+ Ka6
Qb6#
1.Kb6 Kb8 (1…g3 2.Kc7 g2 3.b6 g1-Q 4.b7+ Ka7 5.b8-Q+ Ka6 6.Qb6+ Qb6 7.ab f3 8.b7 f2 9.b8-Q f1-Q 10.Qb6#) 2.a6 f3 (2…g3 3.a7+ Ka8 4. Ka6 g2 5.b6 g1-Q 6.b7#) 3.a7+ Ka8 4.Kc7 f2 5.b6 f1-Q 6.b7+ Kxa7 7.b8-Q+ Ka6 8.Qb6#
kc6!
win…kc6
Draw.
kb6, kb8
a6, and depending which pawn blk pushes, wh plays a7+ followed by kc7 or ka6 winning
h
I agree, draw. White cannot stop the Black pawns so he must attack.
1. Kc6, Kb8! (otherwise Kc7 wins.)
2. a6, g3
3. b6, g2
4. a7+, Ka8
5. Kc7, g1=Q
6. b7+, Kxa7
7. b8=Q+, Ka6
and Qb6 doesn’t work because the BQ covers the square. But White can draw:
8. Qa8+, Kb5
9. Qc6+!
and if K to the 4th rank, Qe4+ picks up the pawn. Otherwise White can check on a8 and c6 repeatedly. Black’s king is never allowed to get to c5 and slip over to the kingside.
Very nice endgame.
if white starts 1.Kc6 Kb8! 2.a6 g3! 3.b6 g2 4.a7+ Ka8 5. Kc7 g1=Q 6. b7+ Kxa7 7.b8=Q+ Ka6 and no mate
if 1.b6 g3 2.Kc6 Kb8 is the same.
but after 1.Kb6! – now on Kb8 white has 2.a6! f3 3.a7+ Ka8 4.Kc7 ! and mates,
on 2…g3 white has 3.a7+ ka8 4.Ka6! and mates.
if black plays 1.Kb6 g3 2.Kc7 g2 3.b6 g1=Q 4.b7+ Ka7 5.b8=Q+ Ka6
b6 is defended, but…
6.Qb6+! Qxb6 7.axb6 f3 8.b7 f2 9.b8 f1=Q 10.Qb6 mate
White wins:
1 Kb6 Kb8 (or 2. Kc7 wins)
2 a6 g3
3 a7+ Ka8
4 Ka6! g2
5. b6 g1Q
6. b7++
