Villain is mid-20s german online player, 2 hands of note:
1) OTB he flatted MP's open 200bb deep with J7ss then overcalled BB's 3b 3way, on the flop BB didnt cbet, MP with a pretty solid image bet 2/3 pot villain flats with flush draw & BB folded, turn a blank and he jammed over-pot after MP checked.
2) he cbet FD 2barreled turned flush and c/raised AI on the river that paired the board vs a tightish player that laid down nutflush only to see villain show Khi flush so I think he's capable of sick moves.
My image was not showing down many hands but pretty aggressive when in a hand however VPIP not looser than usual, all the hands that were shown I had the goods.. and villain's been avoiding me despite sitting to my left.
Effective stacks $4,800
Preflop Villain opens UTG to $70, 2 callers to me in SB with Q

Q

and I make it $420, Villain calls after about a minute, 2 folds.
(Should I have just flatted? His opening range is pretty wide even from EP, I didnt want to turn what's likely the best hand into a setminer since otherwise vs 3 players OOP calling would = throwing away $70)
Flop ($1,000) Q

J

T
Hero bets $500, Villain calls pretty quickly.
(here betsizing is open for debate.. as well as c/r.. I decided on 1/2pot hoping he'd raise...)
Turn ($2,000) A
Hero checks, Villain checks
River ($2,000) J
Hero bets $1,500, Villain shoves for $3,880 total..
Sure he's made sick moves before but this is the first time we have been in a big pot where he's shown any aggression vs me or put in this much money in a 7hr session...
