Lucky fish

I hate it when fish get lucky. This particular guy had been on virtual tilt all game. In a hand earlier, he went all-in with the gutshot on the turn. And hit it.
Unbelievable. Up until this point, I had barely seen a flop. In this hand I limped in with pocket 7's and then flopped a set. I thought this would be an ideal opportunity to double up.
But, the fish got lucky and hit a straight. C'est la vie.
