Help with Checkmate vs Stalemate

Hi all,

New Player

Apologies in advance as i am sure this might be a common topic.  But i am coming up against end results i think SHOULD be stalemates, but are being identified as checkmates.  I will provide the last few moves of my game to see if yall agree.

Setup for Black

Rook on F1

King on G6.  

At this point black is currently in check

Setup for White

Queen on G8

2nd Queen on H8

Knight on G5

Rook on G2

Final Moves listed below

Black King G6 to F5

White Queen G8 to F8 - Check

Black King moves F5 to G6

White Queen Takes Black Rook (F8 to F1)

Black Moves pawn on far side of the board (has zero bearing)

White moves Knight from G5 to E6

The game immediately states White Wins by Checkmate, but the black king wasn't in check for 2 moves beforehand.  I am clearly new, but am i missing something?

The simple answer is, if the king in check and there is no way out of check (moving out of check, interposing between the king and the checking piece, or taking the checking piece) , it is checkmate.

If the king is not in check and there are no legal moves on the board for the player on the move, it is stalemate.

Thank you for your reply.  But isn't that what happened?  The black king was in check initially, but two moves had passed while black wasn't in check and the final move i made was so black king couldn't move.... this is where i get confused.  I thought my moved SHOULD have resulted in a stalemate and not a checkmate.

Update:  Here is a screenshot of my game.  Btw, i am new and am just messing around so i am sure my move list is embarrassing.  But the end moves is what i want to show.

It would have been a stalemate had the position after 57...c3 been "Black to move".

Instead, it is "White to move", so we do not say that Black is in stalemate after 57...c3, since it is White to move. Remember that White is allowed to make a move. Having said that, a ridiculously pointless move from White by, say, 58. Kh1 would result in a stalemate since it would be a similar situation but with Black to move.

Also, stalemate occurs when the stalemated side is having the move and is unable to make any legal moves (not just legal king moves, as is the case in your position). So after 57. Qxf1 the position is not stalemate.

You are missing something.  The king IS in check in the final position, but from the ROOK at g2 (a "discovered check"), not the knight that you just moved.
