10-20 game at Turning Stone Casino. I\'m 2nd under the gun with Pocket Aces. Guy infront limps in, I raise and everyone folds except limper. Flop 8-5-5. He checks I bet he calls. Turn is a 6, all rainbow at this point. He checks I bet he calls. River is a 7. He checks, I bet, he raises and I reluctantly call more to see what his hand was. Guy flips over K-9o, and went runner runner in a headsup pot to catch the straight. Might be the worst thing I have ever seen.
