flag draw

Why on Lichess , when I am flagged and the opponent can't mate ( insufficient material and no possible mates ) , I lose the game ? It should be a draw , no ? what do FIDE rules say about it ? on other sites it's draw !

Hi.
I think you are talking about this game:

https://lichess.org/Q9dl6WCS/black#151

That's not a draw by FIDE laws, because white still can reach checkmate by a legal sequence of moves.
For example, if black goes Kh8 and the Bg8, then white can put Kh6 and deliver checkmate with Bf6

Same thing, white can reach checkmate with a sequence of legal moves.
For example, in both cases if black put Kh1 and pawn h2, then white could mate with Kf1 and Nf2.

@SARHANE87 Just know this, if there's any chance or possibility (be it astronomically low) to reach a checkmate from a given position, keeping in mind the 50-move draw rule, and one runs out of time, it's a loss for the player whose time ran out and not a draw.

Its a misconception that i had myself. In USFC rules, the opponent must have enough material to mate. K+R, K+Q, K+pawn. K+2 bishops. You get the idea.

But in FIDE rules (Lichess rules), it doesnt say anything about the OPPONENT having enough material to mate. The rule states that "If a mating position is possible". Meaning, that if you trap your king with your own pieces and the opponent just gives a check and its lights out you lose. Regardless if that position is achieved with your own worst play that would never happen.

So, for instance, in the first game shown. Imagine a position where white King is in H6 and bishop is on c7. Black king is at h8 and the bishop is at g8, pawn is on the same place.

White to move and win.
Thats why you were flagged and lost. A mating position is possible.

If you do not like that, then play with increment.
