Can you Ace my quiz?

[subzero]

Hand 1: call? according to PokerStove, we have 37% equity right now. The pot is laying 2:1. In FR, I normally call here and fold unimproved.

Hand 2: easy call. closing the action, play for set value.

Hand 3: depending on reads, I think arguments can be made for calling and re-raising

Hand 4: call. why push him off his trash hand? I want the chance to flop a set and stack him.
