Bishop vs Bishop time draw?

First of all, sorry for creating the millionth forum on this same topic; I thought I understood the rules pretty well... until this blitz game: lichess.org/OcztK16DoJHf

We had bishops of opposite color, my opponent flagged, but the position was called a draw. I thought the rule applied on lichess was that if checkmate is still theoretically possible, however unlikely, it would be considered a loss for the flagging side. It is theoretically possible to checkmate with opposite colored bishops, so what's the deal?

I don't bring this up because I want my 10 rating points or whatever, I'm just confused because this seems inconsistent with what I thought was the Lichess policy on flagging. Am I mistaken? Or is this an exception to the rule? A bug?

Well, go in the corner, your Bishop at your side, enemy King opposite and a check on the long diagonal.

Yes Sarg0n, I understand that checkmate is still possible for both sides. That's why I'm confused on why the game was declared a draw when my opponent flagged.

For example, this is a win for black: lichess.org/oV7MTxOs because it is technically still possible for black to checkmate. Why is it different in the game above?

I am sorry, I didn't look at the result. Just read the text and I even misunderstood it.

Back to square 1, no that's pretty inconsequent.

Agreed, this does seem to go against how I understood it to work.

#1 I'll add a test to scalachess and look into it... probably a bug in my latest commit github.com/ornicar/scalachess/commit/57f507b9434f5c84a549b3fcb6965b0af1b4b821 which addressed K+B versus K+Q+R+R+B with bishops on the same color

Would someone who understands Scala please review my fix?

If it is only opposite colored bishops, theoretically there is a checkmate, but if the opponent is not stupid it is drawn.

you're right, that's not normal. if that was a dead draw in 50 moves the draw would be declared at Bxh7 but there is still a tiny possibility of checkmate and your own bishop is still on the board so that can't be a draw by time out.

@s1h3a1s0 Good or reasonable play is not a requirement. If a player runs out of time he loses. That's the rule. The only exception is if it's not possible for him to lose otherwise. This is not one of those cases, so it's a loss.
