J9o in the SB, Blind vs Blind.

[Bob T.]

Online 10-20 game.

Folded to me in the small blind. I have J9o, and I complete. The big blind raises, and I call. The BB, is loose, aggressive, on tilt, whining about bad beats which aren't, and calling people names in a friendly way. He has also chastised me for being a smart ass, which I probably deserved, but he was serving up a lot of straight lines that it wouldn't be right to leave untouched.

Anyway, flop AJ4, rainbow, I check, and he bets, I call.

Turn 2, I check, and he bets, I call.

River 5, I check, and he bets, and I call.

Are there any spots that I could play differently? Was this reasonable?
