My best finish

What do you guys think? I know black screwed up by not doing 25...c1, any terrible mistakes that I or he made besides that?

Also, this is my best finish ever :).

1. b4 doesn't do as much as some other choices in terms of controlling the center of the board, but it's playable if you know what you're doing.

2. Ba3. The bishop sits behind the pawn. This is not a good way to use a bishop.  A better move would have been to play 2. b5 attacking the knight. This forces the knight to move and then you can play 3. Bb2 where your bishop controls the long diagonal going through the center of the board.

At move 4 or 5 you could play Bxf8. When black recaptures he will be prevented from castling. As the game goes, this bishop checks you and prevents you from castling. It's dangerous to have your king in the center.

9. c4. You missed a big opportunity. You can play 9. bxa6 (en passant) and now your queen is attacking the b4 bishop and you can play axb7 next.

18. b6. You ignore the queen attacking your a1 rook. Always look at what your opponent can capture.

Black missed a mate on White.

After 19. Ke2.... If black moves ba6+, White is forced to through the Queen in the way, but it still ends in a checkmate.

Black made some terrible mistakes too.

10... Qxf2 would win a pawn and has got some serious mating threats. 11. Nf3 would be the best move then. It prevents Qxf1#. 11. Ne3 wouldn't be as good, because the black queen will be too dangerous then.

As JonnySleazy said, 19... Ba6+ would be killing.

22. c6 screams for 22... Qa1+ (Kc2 or Ke2) 23. Qxh1, but instead, black blunders by 22... Rc8, which is seriously a bad move.

I'm sure there are more mistakes, but these are the ones I've spotted. By the way, the checkmate was very nice!

well.. all the moves make no sense.. I must say a pretty interesting bad game..
