I think the following line should win for white:
1. a4 a6
2. Ke5 f5
3. Bf3 f4 (no more legal move)
4. BXa6 f3
5. Kf4 f2
6. Bg2 f1Q or anything else then white captures it and the black king doesn’t stalemated anymore.
1. a4 … leads to a win for White
–br
1 a4 ! wins easy
eg 2 Bxf7 … Kf6 to Kd6 Bxc6 c5 – c6 c7 c8/Queen game over (keep eye to avoid statemate trick with black king on a5)
1.a4 a6 2.Kf5 f6 3.Kg4 f5+ 4.Kh3 f4 5.Be2 f3 6.Bxa6 f2 7.Kg2 f1Q+ 8.Kxf1 Kxa6 and white wins
1 a4 is forced,
then 1 .. a6
Try 2 Ke5 f5
3 Be2 f4
4 Ba6 ka6
5 Kf4 and wins.
Difficult to calculate but easy to see the idea IMO.
White easily has a draw so he only needs to calculate the win (if there is one). Candidate moves a4 and axb3+. Since the later is very likely a draw, we focus on the former.
1. a4 a6
Now White has to be careful to avoid stalemate.
2. Kf5! (very important tempo) f6
3. Kg4! (another important move to avoid blocking the bishop’s access to e2) f5+
4. Kh3 f4
5. Be2! f3
6. Bxa6! Kxa6 (…f2 7. Kg2 is the same)
7. Kg3 and white wins.
After eliminating the pawn White marches the King to the queenside and queens the c-pawn using the a-pawn as decoy.
a4, the black king cannot protect all his pawns and is blocked on the side so I think white win
after a4 ,white plays king e7-d6,wins the black c pawn and promotes his own to Q
1 a4 a6
2 Kf5 f6
3 Kg4 f5+
4 Kh3 f4
5 Be2 f3
6 Bxa6
and white wins the pawn endgame.
1. a4 a6 2. Kf5!
(2.Ke5 f5! 3.Be2 f4 4.Bxa6 f3! draws)
f6 3. Kg4 f5+ 4. Kh3 f4 5. Be2 f3 6. Bxa6 f2 7. Kg2 f1=Q+ 8. Kxf1
wins
white should first play a4, to stop black’s b-pawn. Black’s c-pawn is an easy target, since it’s stuck on a white square and white has a light-square bishop. A possible move sequence may be:
1. a4 Ka6
2. Ke7 f5
3. Kd6 f4
4. Bf3
After which white easily picks both the c-pawn and the f-pawn. Of course, white should move the c-pawn to c6 first, before moving his king to capture the f-pawn.
The rest should be easy, as long as white is careful not to stalemate the black king.
V.P.
Easy win. a4 freezes the Black king out. Bishop captures pawn and then King and Bishop move in.
EASY WIN. a4 freezes king. bishop captures pawn and king and bishop work there way in.
1. a4 a6
2. Ke7 f6
3. Kd7 f5
4. Bf3 f4
5. Bxc6 f3
6. Bb5 f2
7. c6 f1=Q
8. Bxf1 Kb6
9. c7 ….
White’s c pawn promotes and wins.
