200NL AK hand, check-raised on turn

Kinda read dependant I guess, but I had none more than that the opp is 35/7/3 but only after 40 hands or so so I don't trust those. I have been raising and taking down most pots uncontested, but on the other hand I've fired close to zero second barrels (without a hand). Standard fold right? Weak? Felt lost so I figured I'd post it.

You'd need a hell of a read to make this call. Its just not worth it. You may be ahead, you may not, but its just not worth paying $x to find out.

Is TPTK ever good after a turn c/r?

Standard set line. Either that or hes a really good player and making a ballsy bluff. He beats a pair tho imo.

Good fold

How would you play A5 here? A9?

(Assuming we take the same line)

I'm not so sure about this since most ppl protect on 2-tone boards if they flop a set. I'd probably fold but I wonder it this isn't as obvious as it seems. I guess we put him on 99-55...

btw I've seen this exact line quite a bit from a hand like 6c7c that picks up a bigger draw on the turn... ppl think they're playing a sit n go or something.

Just fold.

sandstorm,

This is a very common monsterline taken by villian, so unless you have a very good read this is a instafold.
