What caused me to ponder situation 3 was a hand I played a few days ago where basically I 3bet with my KQ, he called and the flop came Jxx. I cbet and he called. Turn was an Ace and I shoved for ~pot thinking I can get him to lay down a load of his range but he called me with QQ.

So this got me thinking about why am I actually 3betting this guy preflop? I'm ahead of his range but I have no FE. I posted the hand on 2+2 and everyone was like "pf is bad" etc.

But is calling better. I think it is in a way but the biggest problem I have with is what I am doing on 735 and other low flops where it is likely that we both missed. I think I need to be running a reasonable % of bluffs in spots like this in order to make calling pf profitable. But I 'm faced with the same problem of having no FE.

So is folding best even though I'm ahead/even with of his pf range?
