i disagree with calling all ins with small pairs, esp. w/ an aggressive opponent and deep stacks. I was playing HU last night and the guy had almost 2-1 chips on me, but i stil had almost 40 BBs. i got dealt 66 in the BB and raised standard raised 3 BB, he came over the top with the rest, almost 40 BBs. I thought for a while, but i thought it was an easy fold. Very next hand I limped with AQ, and he checked. Flopped TPTK, he went all in, i called. he had no pair no draw. He was way too aggressive and way too willing to play big pots at that blind level. Now i had the 2-1 chip lead and it was smooth sailing.
