Few extra notes on the hands above.

Hand 2- I'd prefer to hero call a hand like A6o here than KQ/KJ, even though they are almost the same in value. This is mostly because KQ/KJ block villains gutters, and in the rare chance he turns Kx into a bluff, it also blocks those hands.

Hand 4 - Villain really narrows his range significantly by raising the flop. Or rather he polarizes it more. Having reads on villain, he just doesn't show up with Kx raising flop that often. Given my aggressivenes pre, he for sure 4b/call off JJ.
Flop:
Villains range on flop after raising: KJ/22 for value. I'm not even sure he calls pockets to 3b, so 22 discounted heavily. Value combos (about 10). If we include Jxhh (4) - total combos 14.
Bluff combos: Axhh, AQ, ATs, 9Ts,QTs (31)
Turn: Turn is a great card, his 10 value combos on flop drop down to about 7, and Jxhh likely checks back turn, but if not 11 combos. Bluff combos still 31.
River: Jxhh definitely checks back here, I don't think he expects me to call down so light in this spot yet. Value combos 7. ALLL of his bluff combos get to river and brick this run out. I need villain to have 1.86 (or 2) bluffs on river to make this ridiculous pot odds call. So he needs to shove 2 out of 31 hands he gets to river with, which is very credible.
