Pre
Standard defend

Flop
Not that standard, but i think its still not really close to fold this combo - propably folding KJcc tho.

Turn
Im not really excited calling this, but getting 25% odds, having 8 clear outs and then sometimes K/J and then some implied odds, especially at Q, i think its clear call again.

River
Now its really interesting.

I definetely have in my range 77, 78s, some sets - i think im mixing raise/calling with my sets OTF, definetely again QJs, against sizing i may still even have decent chunk of QJo.
Also a lot of onepair+str8 draw hands that i dont really want to turn into a bluff like J9s/A8s etc.
Then my busted range - mostly Jx hands like this or AJs/AJo and some spades - propably not more than 5 combos.

Thinking in these categories - i propably want to turn all my spades/KJ hands into a bluff.

Villain's line is not really too powerful - id reduce his JQ combos with his small sizing OTT and check river. He's there propably with some 7x and then mostly sets and overpairs.

Should i just ship river given how my range is polarized there? Do you see any leaks in my hand analysis?
