This is the PokerStars Big $7.50 with 24 players left.

I'd appreciate analysis on all streets, specially the river.

My own thoughts:
Pre-flop: standard button open. In my reads, the SB calling range pre-flop is small/medium pairs, broadway suited cards, sometimes QKo and AJo/ATo.

Flop: I checked back on the flop because I wanted to pot control having top pair with a medium kicker and no imminent danger on the board, but maybe it would've been correct to bet to get value from middle pairs and to cash out my equity vs Ax and Kx hands.

Turn: His 1 bb bet means nothing to me, he could be doing it with the entirety of his range. I just call because I want to pot control.

River: His range is polarized and I have a bluff-catcher. Having thought about it more, I believe I should have folded. Although he could have some bluffs in his range, we are losing to 22, 66, KQ, AQ, KJss, KTss, TJss, that seems like a lot of combos that are on his range. And I didn't have any special reads on the guy to indicate he would fire a big river bluff out of nowhere like this.

Thanks for the feedback!
