I cant make sense of this

SB is a decent TAG who likes to call quite a lot oop preflop, he usually takes the initiative on turns when the flopped checked thru and he has a piece. CO is new to the table.

cbet!

here id fold, if he takes initiative on turns, he would lead with a FD here.

Call, you're repping air and he knows it. Spiking a 7 on the river helps too.

I'd cbet, check turn, check down river or call most bets.

As played I'm kind of iffy, I guess fold tbh.

If I call this I expect him to check the river some of the time, so you see his 95o or KJs. It's when he continues with a big river bet that things get tricky..

cbet flop 100% now fold

Don't bet in spots where you don't know what to do if they raise. Your hand had showdown value, and calling a river bet would have been better.

like everyone said, I cbet.
