Hand 1: I don't like. If I'm going to make a stand against someone 3-betting me light, I'll start 4-betting him w/good hands (hands depend on how out of line he has been). But calling with a hand that can be easily dominated is just asking for trouble.
Hand 2: I know your villain in this hand, and I find the stats you have on him interesting to say the least. At 25NL I have 396 hands @ 16/4.5/1. 10NL I have 1K hands on him @ 16/5/2.6. He seems to be playing a lot weaker postflop at 25NL than 10, but his pf raise range is still very small. I don't care much for the board vs his 3-betting range.
Further notes for you...he likes to limp SOOTED cards (last night limp/called 2h5h from utg ). I've seen him shove the river with his busted draw, too.
