Yes, you can. Any endings book should have details, or you can search the Internet. Here is a link I found (there are many others): https://www.youtube.com/watch?v=FvFLNvQ93bQ

EDIT: Or see Martin's link above . . .

 In the unlikely scenario you promoted a pawn to a bishop and now all you have are two dark square bishops or two light square bishops you can't....

But your starting bishops????

Avatar of FonsecaSF

it is possible with two bishops and i believe it is possible with a bishop and knight. With two knights, only with a pawn, i believe.

With just two bishops and no "assistance" from any other pieces, I'd say no. The closest I'd say would be if the king was in a corner, say h8, in this case, the dark square bishop would have to be the one delivering checkmate but the king could escape to the other square the light square bishop isnt guarding, either h7 or g8... but if for example black is being checkmated with the king in the corner, if his own pawn was on h7 and the light square bishop was guarding g8 on the diagonal (say from a2), then the dark squared white bishop could  mate him and he couldnt move to h7 because of his own pawn being there, in the chess.com example posted here, the white king still assists

I agree with mattm. The answer is no. You cannot force checkmate with just two bishops. It always requires assistance from some other piece, either yours or the opponents.

Not if they are both light-squared bishops

Mate can be forced with two bishops (not of the same color). If you don't know how to do it, it will either take more than 50 moves, the position will repeat three times, or you'll get lucky.

You're taking the question too literally.

As long as "both Bishops" are not on the same color, it's clear sailing to checkmate.  grin.png

In a Blitz game I'd probably just save a minute of my life and offer a draw if I got to an ending with 2 bishops vs a king tongue.png  Time is a valuable resource and life is too short to remember or waste time working out how to mate with minimal material!

Yes, but only when they are opposite-coloured and the King is still there to help the pair.

It’s not hard. I’ve never actually had it occur naturally in a game though I don’t believe, but it’s not a difficult checkmate to figure out on the spot, especially compared to the knight and bishop vs. king which you have a zero percent chance of converting unless you’ve seen it before or are playing a daily game 

Avatar of glamdring27

I don't remember ever having it occur in a game I've played.  I don't doubt it isn't difficult to work out, I just doubt if I could really be bothered!

You may very well be right!  Maybe the person just want to know what they would need in a endgame against a lone king, his or her own king of course being a given...on the other hand, maybe the person really wants to know if you can checkmate with just two bishops, for practical reasons or just hypothetically...one practical reason I could think of is an endgame where your king is guarding against a pawn (being guarded by another pawn) wanting to promote so it can't help attack the enemy king, could I checkmate then with just my two bishops if there are no other pieces in the game? I started wondering what would I need in that scenario also
