I played this today at KGS. I won with time, but even though I managed to kill a largeish group before that, I was probably a little behind at that point. All comments are welcome.

Havent time for a detailed commentary but I've to say that the opening looks very "bookish", much better then I would expect from a 8k/10k game!

I'm having trouble opening the game with cgoban (it appears the entire sgf is on one line for some reason, and this is causing problems). However, I will say that his invasion at move 20 is simply unplayable given the status of his group to the left - and you did a good job of completely surrounding it. However, after you surrounded it, you should have played B12 to deny him a base (notice how it makes miai of B11 and B14). B13 or C12 instead of B12 are also good. However, letting him live there is a huge blown opportunity.
