Ruy Lopez exchange, attacking game

Playing games as usual in the slow chess leagues and with weekly partners. Been keeping at the Susan Polgar tactics book. Done a little bit of the "mixed" format at chesstempo.

I'm going to post this game with not much more than computer analysis. One problem I seem to have is that my idea of a proper game analysis is something that would really be quite time consuming. Basically, it would involve a lengthy examination without the computer followed up by a careful exploration with the computer. The problem is that I often find the prospect of my own ambition too daunting so I just don't do anything. At least by running some minimal computer analysis I can hopefully learn something basic about how I played.

In this game I seemed to have a good attacking situation and couldn't pull off a win. It ended in a draw. After the game I was sure I must have had a checkmate that I just missed. Houdini seems to think otherwise. I ran the blunder check and while it came up with some things it nothing really leaped out. However, afterwards I went to a specific point in the sequence and ran infinite analysis and it was showing about a 4 pawn advantage to me. However, the line it suggests doesn't seem natural to me. I guess the thing I am kind of taking away from this is I should have given up on the checkmate and just gone to the endgame up a couple of pawns. I just felt my position with two rooks and a pawn all over his king must be crushing, but it seems there's just not that much there.
