So I had pocket J's and my raise is called.

Flop comes Ks Js 9 and I'm sitting pretty with a set.

I decide to put in a nice bet since I don't like the two spades on the flop and there is straight possibilities.

The other guy comes over the top all in. I have him covered and it's not much more to call. I figure it's worth it to call considering the size of the pot. He could have 2 pair or a A Q flush draw.

He shows 8 10 off. He's chasing the straight.

Turn 2d

River 7 to give him his straight.

I'm wondering why he called my initial raise with 8 10 though

That's Poker!
