On move 25 why does the chess.com engine still have the game as even, when it is impossible for me to stop checkmate with the queen and pawn. Why does the move of my queen to b1 (move 28) give away all my chances. Why is a1 better.

I was just trying to give off checks to try and prolong the game before I was checkmated, but it seems the game was equal by chess.com analysis.

My understanding is that on move 25, when you played Qa1+ the best outcome for you is to repeat moves (3-fold repetition).

White have such a strong attack on the black king (Qg7# and on move 28 the white king has an escape route that permits white to lift/slide the rook on the h column) that any move except repetition only delays the inevitable.

I am in no way an expert chess player so I may be totally wrong here.

++ Because you have a perpetual check that draws by 3-fold repetition.

"Why does the move of my queen to b1 (move 28) give away all my chances. Why is a1 better." ++ Because Qa1+ draws by perpetual check, i.e. 3-fold repetition, while after 28...Qb1+? 29 Ke7 the black king escapes the perpetual check and black checkmates.
