I don't have the HH, so I'm going to summarize...

Villain was a loose passive player. Something like 50/8 preflop. He limped with 40BB behind from UTG+1. From BU, I raise to 5BB with A 9. Only villain calls.

Flop (11BB): A 4 9
He checks. I bet 8BB. He calls.

Turn (27BB): A 4 9 T
He checks. I check behind, figuring I fold all non-flush hands and that I can pick off a bet on the river from many of those same hands.

River (27BB): A 4 9 T 6
He shoves for 27BB. I fold.
