Not much info about V. How do you react on that click 2x raise. There are sets as made hands and only A3 combo which I am blocking. Why would set raise here? The only hand I would be worried about is A3 if I am V. I always see that 2x raise as a bluff. Is that correct? Would you shove here or just call that raise and c/f the turn if he bets?
Pre flop: Ok to defend since perceived V. range is very wide.
Flop: Don't like the lead with mid pair since there's lots of bad turn cards for barrelling. Would certainly go x/c to the river if bets are small. If he pots turn or river it is ok to fold. Since these stakes are so full of fish, I would take the conservative approach, no reason to get out of line with A4s on the semi-ft, and this isn't the exact flop you want to see defending A4s.
As played: Since I don't lead too much in these stakes, I really don't know what to do facing a min raise. Think I would be leaning to bet/fold. Although this flop doesn't hit hard his value range, he still have lots of over pairs to this board. bet/shoving doesn't have any value since MOST people are only calling with the made wheel. Two pair is out of question since "nobody" is raising 54, 52 or 54 from MP. If you have a read on him, which I think you have, maybe it's ok to take this line.
