Not my best game by any stretch, but I somehow pulled out a draw by repetition here.

Just something to note... If someone plays 3...d5 in a Queens gambit accepted you can win a pawn at the very least as follows..

Interesting.  I've considered playing e3 instead of e4, but in the book I'm studying they suggest e4.  Guess I could try it, though I'm thinking of trying the Colle or the Ruy.  I'm not aggresive enough to play a gambit style opening.

You did get lucky. Black could have simply played 64...Kh3 and gone on to win the game.
