1) Villain was semi-raising light In the CO. I wanted to 3bet isolate to play a bigger pot with him. My logic was we're both 200BB effective. I am drawing to the nuts, and i have positional advantage over villain, which was my reasoning for 3bet iso.
2) I mean the flop is such a bad board for me. It crushes villains overall calling range. I mean he should have all combos of 88/99/ some % of JJ/TQs, and low frequencies of 89s.
Flop i thought was pretty standard.

3) I was confused OTT with his double check. Since i would assume he's leading out with all combos of 8X/99/JJ/TQ/JX for value and protection. Also, we're both deep, as the SPR is 1-11.
He checks. The logic i have with my Overbet is i capped his range at weak JX. I should have all QQ+ combos, some 99/JJ that i would also play this way. I dont think i have TQ. and potting with A3s, i could still realize equity vs his hands such as TX random OESD.

4) WHen he raised me, i was confused but ended up folding, since now given board paired, im not drawing to nuts. and i cant possibly see a logical person bluffing at relative enough Frequency vs my Overbet line here.
