i'd make the first pre-flop call without any problem. the second is closer. there is still some chance that utg will make the unlikely limp-call-reraise and kill your hand. also, with 1-2 presumed big pairs out there, you have to worry more about set over set. a flop like AK6 looks pretty good but could easily cost you your stack, so you implied odds are not as good as they look. i'd probably call, but it's close.

on the flop, the only hands you really don't want MP1 to have are AsKs, 77, 88. a lot of other hands are cold calling here - including things like AKo sometimes, 99+, and some other hands. despite what you *know*, there is sometimes that both hold AQ/AK hands or can get away from a small overpair and you win the pot uncontested. also sometimes you get heads up with one of them with AsKs/AsQs and you're 50-50 with a ton of dead money.

i agree that a call is no good. push it in.
