CO - good reg
SB - weak asian semi reg 26/17 5% 3bet, taggish stats postflop, nothing unusual, fold vs cbet normal (40- 50% depending on street)
BB- 27/21 reg with 7% 3bet over 500 hands; cbet on high side IP and ~50% OOP; same aggr as SB 2,4 (maybe it is aggr factor)
Preflop high freq 3bet, as played just calling vs big size sqz.
Flop - should bet sometimes with 66,88, and few good Aces + all kind of bluffs
Turn- don't think BB have many Aces, so likely TT-KK or complete air. SB can have plenty of pp/ other stuff
River - Not sure should I bluff, blocking KK and QQ sucks.
