First Game In Months

So this is my first game of chess since October. I left the game to explore poker and play some online games with friends as they've been begging me to do so for months. 

Anyway - Can I get some feedback on this game? Obviously the guy I played was horrible but I'm more interested in what I could have done differently. 

Thanks

And he resigned on move 16. Oh...and this was a 30/0 game. 

You could not have done anything differently. Your opening was sound and punishing your opponents numberous blunders was really the best way to continue from there.

What about 13. hxg5? Should I have not extended myself so far that I was forced to abandon that knight? 

Pretty nice.  I guess you could have played Bxg5 one move earlier, just for efficieny's sake.

I think you were fine.  Retreating the bishop instead of castling would certainly have been the safer play (and threatens a knight fork on f7) but this worked better.  For example, after 12 Nd5, if he tries to retreat the queen, then ...Qd7 Be6 Qe8 Nf7+ Qxf7 Bxf7 and he loses the queen. 

If there was a flaw, it was that you should have played 10 Nd5 before castling.  Then he doesn't have the option of taking your g5 knight because he hasn't played h6 yet.  After Nd5 his queen is attacked, but he can't retreat it because of the line I gave above, but his only other move is to take on d5 and that leads to disaster.  For example, 11. Nd5 Nxd5 12. Qxd5 Qd7 (anything else loses the knight right away) 13. Be6 Qe8 (again, anything else loses the knight) 14. Nf7+ Ke7 15. Bg5#.

Hi TheArtofWar82--your opponent mostly handled this one for you, but some improvements did stand out.  3...Nc6 is a weaker move and you can take advantage of it with 4. dxe5, when black loses the ability to castle, or with 4. Bb5, when the pin gets annoying for him.  9. Ng5 was tempting, especially since black found the wrong defense in a major way, but what about Bg5 combined with Nd5 instead?  Then you capture on f6 and your queen invades d5 with serious damage instead.  Black could've given up the h8 rook for your e6 bishop and still had a chance, but 9...Qe7? lost badly to 10. Nd5, which was even stronger than when you played it two moves later.  Definitely better late than never though, and that same mantra applies to 16. Bxg5, which should've been played a move earlier instead of 15. Bg6.  All the right ideas were there though, with brilliant attacking and just a little time lost through castling or other stray moves.  Nicely done.

Thanks for the feedback on this game, guys. I'm playing around with the analyzer and looking through some of the lines you mention right now. 

"9. Ng5 was tempting, especially since black found the wrong defense in a major way"

I'm curious as to what the correct defense would be.  White threatens a queen-rook fork on f7.  No black piece can guard the square (except the queen, and that didn't work.)  The rook can only move to g8 but the bishop is covering that square.  The only other safe square for the black queen is b8.  So is Qb8 the correct defense?  I suppose it can't be WORSE for black, but it still looks pretty awful.

Hi DavidMertz1--good question; the reason 9...Qb8 falls under the category of "less terrible" is because it keeps the a8 rook defended and doesn't allow 10. Nd5 with a tempo gain.  The best white has is 10. Nf7 Nd4 11. Nxh8 Nxe6, when he picks up the exchange but little else.  Definitely the lesser of two evils for the losing side here.

Hmm... after 9...Qb8 I'd probably not play that line; it wins the exchange but at the price of the knight being trapped in the corner.  I'd probably play Nd5 instead.
