$600 effective. I open K♠ J♠ to $20 in HJ over a limp, young grinder-looking kid 3-bets me to $75, folds to me, I 4-bet to $150, he hesitates for a bit and calls. I sat down like 5 minutes ago and I don't have any reads on him.

Flop: T♣ 4♠ 3♦ Pot $312 I bet $100, he calls.
Turn: 7♠ Pot $512 I shove $350
