Reg from the button has 3-betted 2/7 from bu. What do think is the best line here, just call and estimate otf, or 4bet? I think the problem with 4bet is just, if opponent 5bets we are always screwed, and we can only hope, that he has AK. 
So with 4bet we kind of turn it into bluff, because we cannot call the all-in, so random Ax may be even better for 4b than JJ.
What do you think guys?
