Table is mostly MAWGs. Villain is MP3 at 9 handed table. Hero is on the button.
Table dynamics have been mostly fairly passive and loose. Rarely seeing 3b pots and plenty of MW pots going around. Hero has tighter image, but no extensive hand history with rest of the table. Villain tends to do a lot of calling and x/f in MW pots.
Villain is the effective stack at ~$180.
Action begins with six limps before it gets to me. I look at AJo and raise it to $21. MP3 is the only caller.
Flop comes AA5r. Villain checks. I check back.
Turn is a 6, completing the rainbow board texture. Villain leads for $45. Hero calls behind.
River is an 8. Villain thinks, then jams his remaining $110.
Hero ???
I think my biggest misplay here is the small raise, given the six limps. Would a more appropriate size be $30-37 here? I'm fortunate that this didn't go MW given my sizing mistake.
As far as flop goes, I think I am far ahead of Villain's range after the check. I know live people do tons of weird things, like limping or overcalling AK/AQ, but I have removal and I assume villain will raise AK at least. I think about betting 33% pot here as a range bet, but decide on checking back. FAFB situation.
I think turn and river ap were fine in retrospect. Our hand is not vulnerable to be outdrawn, and by mixing my checking range with my stronger Ax hands I can bluff catch here. Villain will likely overplay his smaller Ax or not give me credit here given the flop checkback.
Let me know your thoughts.
