Ok lets start with what we already know:

-100 bb or less just raising/shoving gl

-200 bb + call see a turn etc.

So what to do here? I mean i'd be calling seeing a turn here tbh, i'd need a reason to be raising this flop, the main problem is that he still has a bunch of marginal hands at this point AK AJ 99- which are ofc ahead of your hand but aren't playing to a c/r, which moves the hand on, ofc the problem is that any Q hand he calls you with has you drawing to 9 outs..

When you call and the turn wiffs you do you bet when he checks to you? I think I probably.. would in this instance unless I pick up a heart draw.. I'm not positive I normally advocate checking back the turn in these kind of situations I'm just not sure that he can really afford to check weak unmade hands to you on the turn, but in alot of ways i guess it depends on the guy and your image, I mean if you think he's c/ring you on the turn with AT and JJ then def check back behind.

It's alot more close here than people think though, normally people just instacall flop and take it from there, good post fayth.

obviously I suppose the lines you take in later streets are very player dependent and with this guys stack I'd probably lean towards the weaker/tighter moves if he is completely unknown to you.
