After going through my game, I saw one major blunder by me.

20. kc3

I was one move away from checkmate. 20. ... Rc4#    

Lucky for me, it was overlooked.

Are there any other things I overlooked? Any advice is greatly appreciated. I'm still learning :)

7. a3      instead just play dxc6 ( you take later on but he could of saved his knight if he played Bxc3 )

15. Qb4   could of played Rd1 which protects your king after Bxd1 , Qxb1 and then later develop your king side pieces ( being the exchange down in this situation isn't a problem seeing the vast material advantage you had )

just a few i saw while looking through

overall good game and nice finish just try and protect your king even at the cost of material when you way materialy ahead

7.a3?? - This not only missed your chance to win on the spot, this even gives your opponent an advantage. 7.dxc6! was winning. 7.a3?? Bxc3+ 8.bxc3 Qxd5  and Black's regained his material with better development.

10.e4?! - Look at the board. You're up a piece--that is completely winning. The only problem is your opponent is better-developed. In light of that, your priority should be setting up a safe pawn wall and developing your pieces. Play e3, Nf3/Ne2, and Bd3/Be2. Then Black gets no counterplay.

11.cxb7! - This is good, since Black just moved his bishop away and will have to waste time responding to it.

12.bxa8=Q! - Also good. Your opponent doesn't have enough attack.

13.Nd5 - Ok.

14.Nxf4? - But why? 14.Qb4 and you're up two pieces and your opponent's attack is dead on arrival. If 14...Qe8 then 15.f3. When you're up materially, you should aim to prevent counterplay. That's more important than winning more material. After all, an extra rook and knight is plenty to win with.

15.Qb4? - 15.f3! would've been a more accurate defense, when you stop your losses at a rook and 15...Qxa1+ is met by 16.Kf2. 15.Qb4?? throws away all your gains.

16...Rd8? - 16...Qxf1 wins the hanging bishop.

17.h3? - 17.Nge2 defends d4, which your opponent just attacked, as well as defending the bishop on f1. 17...Bxe2 is met by 18.Nxe2 and your position seems to hold together.

18.Qxa5? - This was another chance to get back in the game. Instead of blunting your opponent's attack, you went for one more pawn. I'll say it again. You're two pieces up. Don't give your opponent any chances.

19.Nd3? - 19.Ke3 and Black has trouble pressing the attack--his bishop is hanging, and his Queen is tied to protecting his rook, and his back rank is weak.

20.Kc3?? - Falling into 20...Rc4# and it's game-over. 20.Ke3 is again best.

23.Qa8+! - You see the back-rank mate and win.  :)

You were inaccurate in defending Black's attack, but I the real lesson is: When you're up by a piece or more, think defense first. (1) 10.e3 followed by Nf3/Ne2, Bd3/Be2 and you're simply up a piece. (2) 14.Qb4 and you're simply up two pieces. (3) 18.Qc3 Qxf1 19.hxg4 and you're simple up two pieces. Be greedy only until you win a piece.

FryTheSolid> 15. Qb4   could of played Rd1 which protects your king after Bxd1 , Qxb1 and then later

It's a good try. The refutation is 15...Qc3+ 16.Rd2 Qc1+. Because White's king doesn't have the f2-square to flee to. 17.Rd1 leads to a draw by repetition, so White's only try is 17.Qd1!? Bxd1 18.Rxd1 Qxf4 19.f3 when it's R+Q vs R+R+N+B. White is still a hair better, but it's going to be a wild ride due to the crazy imabalance. :)

15.f3! settles things right away. 15...Qxa1 (Black regains a rook) is met by 16.Kf2 and White remains two pieces up with an easily won game.

If White had played 14.Qb4, thinking defense first after reaching a completely winning two-piece-up position, none of these complexities would occur.

Also, you have selected for yourself a fine user name, so I'm sure the mind behind that handle will do well!

ILLYRIA: lol ;) Thanks.
