Table fairly loose/passive standard. MP is exception, raises a lot pre, bets a lot post, seemingly indiscriminately.

Recent hand, MP raised A2o after a couple limpers, bet Axx flop, called a donk on a blank turn, then checked behind river, chopped with A6o because of overcards on board.

I was sort of thinking about what kinds of hands I would c/c vs this opponent over multiple streets when I look down UTG and see AJo. I limp (not great but I don't hate it, very passive play), one call, MP raises to 10, one LP call, I call, initial limper calls.

Flop, A84r, pot 40ish. check, check, MP bets $20, fold, I call, call

Turn, 5x, pot $100ish, check, check, MP bets $35, I call, call

River, Tx, pot $200ish, check, check, MP bets $50, I call (shove? all have about $50 more behind)

Good/Gross/Lazy/Fishy?

P.S. Random in this hand has made many bad multi street call downs
