sometimes just the opposite is true. i'm stealing, BB calls. I hit top pair and BB already was playing a big pair and his check raise allin after the flop looks like he doesn't believe i had a hand preflop and has decided to look me up. I have hit top pair, I call and bam run into a huge pocket pair.

Perfecting my blind steals and/or blind defenses would be my biggest leak. And its not that i try to steal or defend too much, maybe on the average of once every 2-3 orbits.
