2 bishops of the same color

I was winning a game and I decided I would try something unique instead of getting a rook or queen in the end game I would try 2 bishops of the same color to see if it would give a draw, surprisingly to me it still gave me the win, now how is it possible to use 2 dark bishops to win a game with a king?   I think chess.com needs to fix this

any thoughts on this?

It is not possible to mate with two bishops on the same colour because the king can just stay on the light squares and never get checked.

Chess.com thinks this is a win for you because it only checks your material. In fact, it thinks you cannot win with just a knight against a pawn, as I have seen a few posts of games that were drawn on timeout with insufficient material, where the opponent timed out but it was a draw because the opponent "didn't have enough material to force a mate".

No it doesn't.

"6.9 - Except where one of Articles 5.1.1, 5.1.2, 5.2.1, 5.2.2, 5.2.3 applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by that player. However, the game is drawn if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves."

This quotation is from the FIDE Laws of Chess regarding draws by insufficient material. Since your opponent had a pawn, and the possibility to checkmate your king, they didn't have what is considered to be insufficient material.

How is black winning when they have insufficient material?

So if my opponent didn't have the pawn then it would be a draw I guess lol

i guess you won on time =D

Chess.com sadly, but understandable, doesn't use Fide rules in the case of insufficient material. They need something that is more easily evaluated than whether or not to be able to mate.

time doesn't matter if you don't have sufficient material

yeah even though its possible, no one is gonna be stupid enough to put their king in a corner unless they are 200 elo and dont know any better

The disadvantage is incredibly less than one might first think. Half a pawn to a full pawn in general. Assuming one player start with two bishops of same shade.

I just think it is utterly rediculous to award me the win when there is nothing I can possibly do to make the king walk on a black square lol

Wait you're right it should be timeout vs insufficient material

It would be nice to know what you're talking about. Not about the position in question, that's for sure.

yes because there is no way I can mate the king unless his pawn never moved and allowed my king and 2 same shade bishops push him in a corner and even then, is it possible

Back in the day, everyone thought having two bishops of the same color was a huge liability. But lately, new studies are saying it's not nearly as bad as we thought. I even ran some computer tests, and it turns out chess engines don't have an easy time beating someone just because they have two same-colored bishops..

ah, what a fool I was last year. Yes, it never matters. This is a bug for mods to fix

But you do have sufficient material. If you consider all the pieces on the board. Yes, it's highly unlikely the opponent would put himself in a losing position, but it IS possible. So (improbable) sufficient material exists. So the game was decided based on time, not material.
