hand 1, I surely call but I think you are going to lose a fair amount of the time. Given that he will probably try to get in a/i with 2 pair, I think you gotta call.

hand 2... I am thinking you may not want to lead the flop against a tough player, if you are even somewhat tight. bet-3bet a/i make sense if he is raising your flop bets alot, but high variance.
