Nice to see some games being posted around. But here is a challenge: Find the longest endgame with 7 pieces or less where one side can actively win!

How about this?

But aren't you only allowed to have 2 of those?

Rook and Pawn vs Both Are Untakable Bishop and Pawn Fortress (you might have a guess what that is happy.png. The same imbalance happened in a master game, and believe me about this, it was a hard win for the rook and pawn. In fact, the Master with the Bishop and Pawn resigned in a position in which I never would have resigned and I think I could have made a draw.

Queen and knight always beat rook bishop and knight, but mating takes up to 545 moves.

And it is the longest 7-piece endgame! What mathematicians can do today!

This is not a draw. Cut the defending king off, attack the bishop and/or pawn with your king, and sacrifice the rook. If black's king was defending the pawn and bishop, then this position would be a draw. If the king is far away cut it off and sacrifice the rook.

A real tournament game where an underpromotion to a knight resulting in a 3 Knights vs 1 knight endgame occurred!
