Can white win this?

Sort:
JohanVA

In this position, black to move, black went for the trade of bishops resulting in a won ending for white. But if bishops stay on I can't really figure out how to win as white. Is it even a win? Any ideas would be appreciated.

The actual game: Schaken: JohanVA vs CapaSchach88 - 605696299 - Chess.com

I think that white can win if white goes after the a pawn even at the expense of the e and g pawns. I think this because if the black bishop leaves the a5-e1 diagonal, white will block the b pawn and take that diagonal and win a5 pawn and even if black takes one of whites pawns whites majority will rain supreme. If the bishop stays on the a5-e1 diagonal it is a bit harder and white has to play Bc3 at some point to remove the black bishop or trade into a winning pawn endgame. Here is a practice game I played against The Magni to demonstrate this plan.

Black is completely lost in this position no matter what he does, I have an engine named "Slowchess 2.9" that says White forces checkmate in no more than 36 moves from this position:

drdos7 gives a line with the wB outmanoeuvring the bB but for a game player the line with the bishop exchange is equally educational. To take the black fortress white needs to sacrifice its crown jewel:

Indeed after Black exchanges the Bishops he is completely lost, but the endgame is instructive, there's a little improvemnet in your line to 52.g7!

Ah yes, the famous triangle. Which makes the pawn sac nice but not necessary! And this line is probably more effective in some related endings.

Think I got it, thanks people.
In the game I had indeed planned Arisktotle's line with the sacrifice of the g-pawn, didn't think of the nifty triangle. Of course, black chose to walk a different path.

White to win. They have a pawn advantage. Pawns help me defend and they're sacrifices for the king.

That looks hard but I think white could manage to come out on top

i think black could draw it if he stayed near the pawns queening square. right?
