Check, V goes AI.... Its overbet:

2500 into 1170, I have 2300 behind.

If he bet 800-pot I would lean to fold, this overbet
puts me in tough spot.

Its LIVE $1 $2 i.e. 6 12 in this case...
Villain is agro competent player, lost big pot vs me 20 min ago, yesterday he rereraised 3w on
flop 774r after preflop bettor bet into 3 players w QQ, 2nd player raised w 99 and this player made move w KT and folded out QQ, but not 99.
It was surprising play for me from all 3 players in that hand.

What to do w flush in this hand?
