First of all, congrats on the new site Bart!
Will save detailed personal thinking for later but welcome thoughts for any street.
$5/10 live 9handed NLHE, $1200 effective (I have button villian covered), in SB with Ah9h
I have not been in table long and not been active, villain is unknown but has been involved and aggressive, but hands not gone to showdown -- youngish 20 something guy.
one MP limper, button raises to $45, I call, BB call, MP limper calls, $180 in pot.
Flop comes AcAd7s.
I check, checked around to button, who bets $100.
After some thought I call, folded around.
I check, he bets $300, after some thought I call.
I check, he moves all in for ~$750. Thought? Tx in advance.
