White to play. All comments and analysis are in the spoiler.



Spoiler:
This comes from the book "Imagination in Chess" by Paata Gaprindashvili. I thought it was a really nice puzzle. Here's the solution.



How many of you were able to solve it? I need to know who to never play in a game

And here's the full game if anyone is interested.

My analysis is the following

Spoiler:
Our dark bishop is under attack by a pawn. Our light bishop is under attack by a bishop.

I think its better to analyze how to save the bishop that is under attack by a pawn.

The first option is capturing the pawn. Bxe5 fxe5...doesnt seem to lead to much.

Moving the dark bishop has the problem of abandoning the light bishop. Unless we move it to b6. If Qxb6 then we do Bxd7. If Qxc3 then Qxc3 Rxc3 and Bxd7.

That seems to work, let me check the spoiler

You are still safe to play me, .

I looked at the move but certainly didn't see any way to make it work
Spoiler:
After Qxd6.
My "solution" was essentially what V proposed in his spoiler:

Spoiler:
However, it seems after: 1. Bb6 Qxc3 white's b pawn falls and black should have an advantage even without the two bishops. While white will control the light square holes, black's pawn structure is much more solid and I see no good way for white to continue advance the d pawn - black has a pretty effective blockade - or to win the b pawn, or to effectively attack the king even with the very weak white squares surrounding him. Those are the three ideas I see for white to win while black has three weak pawns to potentially attack: c, d, and f pawns.

I don't see a completely concrete continuation except I don't see how to save the b-pawn or how to either win black's b pawn or effectively push the d pawn.

White certainly doesn't seem better overall to me and it seems black has an advantage even though white now has the two bishops since black has "fixed" a discombobulated pawn structure for white.

Why can we only post uninteractive FEN diagrams here on 2p2? It would be really, really nice if we could post PGN's like we can on most of the other chess forums around the web. Just saying.

PM Mat Sklansky and include some advice on how to incorporate it into the software.

There are some solutions, but for good reasons 2+2 doesn't want to rely on a ton of custom code. Especially for a very small part of its userbase.

Can we post PGN text in a thread? This way anybody can use whichever viewer they like so we can review games in their entirety easier?

Just testing this out. This is a game I played yesterday in the 15-minute auto pairing pool on ICC against a guy who was rated 1410 in the pool at the time and I was rated ~1120. I could have won this game but the time trouble eventually made me shoot right for a draw with the black pieces vs an opponent nearly 300 points higher than me.
