With Black to move, is there a possibility to win in this position?

    This question is sort of like asking if Hitler had a winning strategy in April of 1945. – John Coleman Jun 13 '20 at 16:57

At a cursory glance you see that...

  • white is up a piece and a pawn,
  • the black queen is pinned to the king and will be lost,
  • white's pieces are much more active than black's
  • white's king is safer than black's
  • ....

So no, there is nothing, really nothing in favour of black here. The only thing which needs to be checked is that Qxe1 is not mate, but in a millisecond you see that the rook is protected by the knight on f3.

Of course there is. If White's flag fell then this would be a win for black.

Here is one simple winning continuation for Black

[FEN "3rk2r/1p2q2p/1Q1p1Bpb/1R1N3n/1P6/5N2/1P3PPP/4R1K1 b k - 0 1"]

1... Nxf6 2. Nd4 Qxe1++

Of course the White move is very bad and only someone who is trying to lose (or teaching a young child to spot back rank mates) would play it but it is one of many possible ways that Black could win.

Of course in a normal competitive game it is never going to happen. With reasonable, half competent play by white black is going to lose.

  • The fact that white could move in such a way as to lose should be important in the scenario where white's flag falls. If the position were such that no legal moves for both players could result in white being checkmated, then even if white's flag were to fall the game should be drawn. The rules are clear that if a position is reached where no legal sequence of moves could checkmate either player, the game is immediately drawn and unaffected by the clock; I don't think they're completely clear about situations where e.g. there is a sequence of moves by which white could checkmate black,... – supercat Jun 13 '20 at 16:57
  • ...but not vice versa, when white's flag falls. If e.g. pawns were permanently interlocked and black had lots of material on the side opposite the white king, I don't think there's any procedure to establish whether the game would be a draw or a win for black. – supercat Jun 13 '20 at 17:01

The position is resignable for Black. White is already up a piece, and is about to win Black's queen for a rook. Technically it's possible White could play some horrible blunder and allow Black to win, but this could be said about any position where the losing side has mating material.

No, this is dead lost. According to stockfish Qxe1 is Black's best move. But even after this, White can force a checkmate in 13 moves.
