thanks for the comments - pretty much everytime I post hands here someone exposes another leak! I should post more hands...

I'm going to further examine 3-bet sizing. One thing I think (hands 2, 3, & 4) is that 3-betting is by default smaller when the standard open is 3.5bb rather than 4bb. Also, any 3-bet >pot is bad cos of the bet pot button. I'll look further at 3-bet sizing, I may be going a little light in general (generally pot less 1-2 xbb)

hand 5 - Agreed that leaving him with that little behind is unusual, but he's bad and won't realise that he's pot committed now. I wanted to get a call not a fold, and i don't think he's calling his stack to a flop re-raise here
