Interesting stats. You're a bit too tight, but this seems to be healthy caution rather than fear.

I am surprised AA isn't your biggest-paying hand, and I am also surprised that you're only getting 4 BB/100 with KK (I have a BB of 11 for AA and 8 for KK and my overall BB/100 isn't much above yours, albeit after only 20,000 hands recorded).

I would also want to see a few more showdowns if I were you - only 20% is just too low, and means that without a doubt you're throwing away winning hands. But you are winning 60% of the showdowns you see, so clearly you are still playing the best hands correctly.

Are you British? I play at William Hill on the Cryptologic network so it'd be an interesting comparison to swap stats
