I am new to live nlh games, having only played about 100 hours. Would like feedback on a 1-2 game hand. The player utg was a good lag player and opened for $10. A nitty player utg+1 called. I had a somewhat nitty image and re-raised to $37 from mp2. The villain, new to the table, had about his starting stack of $300. He called my raise from the button. The other two players also called. I had Kd, Ks. The flop was 9s 6s, 2c. The first two players checked, I raised all-in ($330) and the villain called off his remaining stack of about $260. The other two players folded. The villain shows 8c7h. The river brings the ten and a straight. Did I over play the Kings, get very unlucky, or both? Would appreciate feedback, thanks.
