Dealt to Hero Q A

fold, fold, fold, Hero raises to $10, fold, BB calls $6

FLOP ($22) 4 K Q

BB checks, Hero checks

TURN ($22) 4 K Q 5

BB checks, Hero bets $16, [color=red]BB raises to $64, Hero ???

sometimes i check back flop with weak draws, weak Q or something similar. i know the standard is to cbet for value from all underpairs, Qx, draws etc, but i decided to mix it a bit, not sure if it is feasible to do it against unknown... anyway as played do u call turn ? and them what do u do on blank rivers when he bomb it ?

site is rigged.

assuming 2nd 4 is 4d instead, its a spot where its highly dependent on whether you think hes capable of handreading and doing this as a bluff. this is why id much rather cbet the flop than check if i have no reads on whether he'll do this with 100% of his range because he knows we will cbet all strong hands on flop.

I would call then c/c a river blank

ah i deleted some part of the hand and obv when rewrote made mistake edited OP

against an unknown just cb flop
