I liked this game...the computer analysis didn't.

A 3/2 game I just played against an equally rated opponent:

Nice win with the killer king gambit 

yes

64 percent computer accuracy, but still the position is pretty nice

very nice execution of king's gambit.

and also 23. Rb8++

That was a nice game :-)

Isn't 23. Rxa6 also mate?

I think that CAP score is a good measure of play, but I don't think that you should take it too hard if you get a low score.  It just means you don't play like a computer.  64 percent accuracy really is fine.  Here's how I interpret it-

100%- played best moves possible according to the engine analyzing them

90%- played most of the best moves, either had a really easy game or played really well against a difficult opponent

80%- had a good game, with more than enough "best" moves and maybe a few suboptimal or inaccurate moves, still a well played game

70%- either played a few mistakes/inaccuracies, or played a more unique setup that the computer hasn't thought of, nothing to worry about

60%- a game where both players had small chances, but one outwitted the other, no serious blunders still

50%- a possibly questionable game, probably with at least a blunder, if not a few mistakes, with good play otherwise

40%- very unorthodox, in the bad way most of the time, not many great moves

<30%- player did not know how to play the game, or respond to a gambit, just generally a losing game

Good game! Who cares about the computer? It has no heart or soul!

23. Rxa6?  Bxa6

It does has a chip on it's shoulder.

I didn't see that... I like it even better than the text.

do you accept friend requests??

I like it. You only had a bad accuracy because of some missed opportunities in a short game. Sometimes, the computer doesn't understand what is a missed win and what isn't. 

I must be on needles and pins. 

nope.
