[9cao]

I don't think it is that bad. A weak lead on the flop, call a raise, and lead the turn could have worked nice. I think 4-handed you would have a very tough time getting away from this since there are some hands you still beat. Looks like a flopped boat with 88 since as you said he usually bets the flop. I would have expected AQ to go all-in on the turn but I guess that is an option too.
