i would want a read that $200 into ~$300 pot means draw/medium-weak hand and that he will let us realize our eq by just calling the times we are behind. obv ppl will ship sets and prob top2 vs ur sizing but if he ships weaker 2p or even a combo draw then we are setting ourselves up to make a mistake by raising. without a read on the bet size i doubt we are pushing eq vs his range even tho we increase our implied odds (maybe) if we hit our flush or str8. if the caller comes along then thats good too obv, but we cant really vbet any rivers unimproved nor would we wanna bluff the river (assuming avg live opposition) so i think the cons of a raise outweigh the pros.

vs a range of K9+ we have 27,3% eq. to gii we need 32,6% equity unless i misread the stacks or made a mistake. if there is a chance that he is capable of shipping with 1pair+draw or a OE/wrap+fd or the weaker 2 pairs (add all K3+ but no 1pair+draw or naked draws and we are breaking even on a call) then it becomes a close but clear call.

The important thing to understand is that when the hand plays out like it did, it's a HUGE disaster for you because you lose a big bet and don't realize your equity. I would be quite happy to call and play the river in position.

Just don't see any value in the turn raise.  Most of what they're folding you're ahead of and have good enough visibility.  You're just value cutting yourself
