4 handed
Villain is another 2+2er, goes for comically thin value sometimes. Balances his ck/r, leading, and flatting range well.
Previous hands, 5 handed:
1) I iso'd to $60 OTB with QQ and he defended his BB with KJ. He ck/r'd a K49 flop, checked a 4 ott, then jammed a K otr.
2) Villain raised to $35 UTG with JJ, I called OTB, as well as SB. We all checked a T9x flop. He bet a blank turn...me and SB called...then he bet 1/3rd pot on 9o river.
3) Villain raised to $35 UTG with 55, got 3 callers. Ck/r'd a Q85r flop, initial bettor jammed and he called obv.
4) Villain opened to $35 in the HJ with K8c, I defend my SB with 99. Flop came A63, he bet and I called. Turn came a K, ck/b/c again. We both ck'd blank river.
Villain usually doesn't ck/r that often and plays hands at face value, betting out...but was ck/r'ing all night to mix things up I guess.

When the river came out, I said "Great, now he has quads"...after that he smirked, asked for a count, then moved all in.
