Unexpected win!

Heres my second upset in the middle class tournament where i was down inventory due to bad play but then my opponent handed it back in an unexpected way pls tell me what i could have done better as im not sure.[Event "Online Chess"] [Site "Chess.com"] [Date "2008.06.27"] [Round "1"] [White "ChessMaster2000"] [Black "sinclair56"] [Result "0-1"] [WhiteElo "1350"] [BlackElo "1307"] [TimeControl "1 in 3 days"] 1. e4 c5 2. c3 e5 3. Bc4 Nf6 4. Nf3 Nc6 5. Ng5 Rg8 6. Bxf7+ Ke7 7. Bxg8 Nxg8 8. O-O Kf6 9. Nxh7+ Ke7 10. Nxf8 Qxf8 11. d3 Nf6 12. Bg5 d6 13. Bxf6+ Qxf6 14. c4 Nd4 15. Nc3 Be6 16. a4 Rh8 17. h3 Bxh3 18. Nd5+ Ke6 19. Nxf6 gxf6 20. a5 Rg8 21. Qh5 Bxg2 22. Qh2 Nf3# 0-1

p.s. have no idea how to add chess board with view of game without writing it all out.

Ok Rg8?? was a mistake better is d5. 8.)Kf6? what the? better would have been either Ke8 or Nf6 at least u allow more development. 9.) u should have played Kf7 i feel. 17.. wasnt a good move really u could have played Qg6. 20.) for white what the? y not just kill the bishop? 21.) Bxg2 nicely done now he is in trouble. i dont think he has a good answer now. So well played u got lucky this time...

Wow that was sweet my friend, This is a fine example of how the knight's unique ability to attack specific squares on the board proved very benificial for you.

AWSOME JOB!!

sweetness dynomite win

wow nice win.. just when as seems lost... well done

Nice.

I think your opponent and you made really obvious dumb mistakes. I guess for your rating it was ok, but Rook g8?? Plus you handed him your queen too. A little thinking by your opponent and you would have completly destroyed. But still, that was a nice mate.

mating in chess is everything, and leaving your king in danger is worse than losing some of your peices...

wow very nice

very very nice ending. i would have probably resigned after i lost my queen haha.

I think you had to play 5. d5 to stop the double attack on f7

How on earth you used chess master 2000 ? If you load it on a system with hard disk bigger than 500 MB it can not read its file !! Only way to run this old dos program is to run from a flopy. I have even older chess programs in DOS. 

Very good ending.lucky
