I agree with rilla about the second hand.

Exception is that he reraised for isolation/dead money issues.
Sometimes if someone normal raises and I hold a small PP I will reraise like 3 times his raise if there were like 3-4 callers (repping AA/KK) just to get it heads up + the dead money. Then I can take it down on the flop cause of the strength I have shown pre flop. Of course I lay down if he re-raises or if I get another caller and I dont hit.
