[Man of Means]

Hand #1 you can check/call to the river (then b/f or c/c or even c/f river) if you have decided to see the flop. In a live game, I'd sometimes fold A7o-A2o here since people are generally not hip to "blind steals" and they actually openlimp on the button a lot with medium strength hands.

Hand #2 Opening ATo is somewhat laggy but I've done it under the right conditions (tight-passive table where I haven't been opening much due to crappy cards or whatever). Once you flop trips, it's hard to get away from the hand but I can't think of a hand that doesn't have you beat unless Button is a nutjob. You have outs against QQ and KK. Would he fastplay AK on the flop? Sorry, just pay off and chalk it up to metagame.

Hand #3 Bet the turn, then the river will be easier to play. Since you have the read that he doesn't v-bet much you might be able to make a fold.

Hand #4 Ugh, go ahead and raise if you think he "has a piece" and is testing you out. I hate the EP caller in between. If you see an Ace on the turn and EP likes it, get ready to bail.
