Re: results
 

Hard to imagine him not raising the river.

I agree with the others who said bet/3-bet the flop. You have a better chance of finding out if you are in trouble earlier in the hand and against a LAG like this you are frequently extracting more value.

Re: 5/10: oops. who did I just trap here? (AQs SB)
 

Since he is loose-neut, I think he is has AK, TT or 99 close to but not quite 50% of the time here. I cap the turn, then bet-call the river.

EDIT: too hasty, forgot A9, AT. That pushes it closer to a turn call, but keep the river bet-call. Given that opponent is loose, I'd still cap the turn here usually, but am less confident in this answer. I'd really like to know how s/he plays Ace-middle.
