it seems lately im getting every cbet in 3bpots shoved on... is there any other way to play this with the info i have? i feel like i could still be ahead... but i doubt he folds any pp and certainly not an 8 or 9. i feel i should be using position more... im generally cbet/folding or getting ai on the flop in 3bpots

anyone like a check behind on the flop?

thanks!
