[Site "Chess.com"] [Result "*"] [SetUp "1"] [FEN "K1R1QB1R/PP3N2/2N1BP2/pbP3P1/2n1p2P/3p1nb1/1pp3pp/r2kq2r w - - 0 1"]* I saw this mate online, but it was black to move. knight goes g6 to check king. but then it becomes a mate, and pawn is unable to take.

There are two problems with your FEN string:

1 - In your FEN, the ranks are listed in reverse order. They should be listed from rank eight to rank one.
2 - If it's black's turn to move, then the 'w' should be a 'b'.

I think this is what the FEN string should be:

[Site "Chess.com"] [Result "*"] [SetUp "1"] [FEN "r2kq2r/1pp3pp/3p1nb1/2n1p2P/pbP3P1/2N1BP2/PP3N2/K1R1QB1R b - - 0 1"]*

thanks for the correction, I just copy and pasted this and I understand it's not blacks turn to move, but in the case of it being. it was mate upon knight move. so my question was how can the pawn take?

Or why can't it take? I mean. Because there's no discovery if pawn takes to eliminate check.

I realize something happened and when I pasted this, it glitched out. my bad, no need to reply.

The pawn should be able to capture, unless we are facing an unlikely situation where the White pawns are heading the other direction (often a cause of puzzle failures myself!)

In the post manekapa provided, the equivalent "g6" check in that diagram is b3. Had there been no pawn on a4, Nb3# would have been checkmate since the pawn on a2 would be pinned to the rook on a8.

https://youtu.be/qxzmkDXSmX8 it's at 5:00 for anyone still curious about this post. I tried making an FEN to understand why even, but it was no help.

You seriously have to pull your thoughts together, and try to explain what is that you don't understand. In that game I can't see any moment when a pawn can't take something for whatever reason.

Yeah, thanks pal. Anyways at 5:00 my brain was thinking just take the knight with whites pawn.

At 5:00 there is no white pawn that can take any knight. Are you talking about 5:33 and after?

PawnzNiemann

there is a pawn on h2. OMG I'm so bad with coordinates

PawnzNiemann

sorry for the sarcasm. I'm just so frustrated that I made such a disorganized post in the middle of the night that I cannot delete... ugh anyways. Alex says mate in 1 and it is, but it's not registering.

magipi

Okay, I repeat: are we talking about 5:33?

yessir.

The h2 pawn can take on g3. The game is not over, the clock is ticking. Then white resigns at 5:59 (because he would get checkmated in 2 more moves). You can see chess.com declaring "You win by resignation".
