screwed again

Everything was going great in the $5000 plhe wsop event today. I had about 27,000 chips at the end of the 4rd level when average was 7000 or so. I was pwning the fish nicely until this hand screwed me. There was this rock that just went from 6000 to 19000 chips cause he had AA twice in a row and basically doubled uo both times. There was some confusion because there was a guy that had blinded off, as he never returned from the 2nd break, who had 50 dead chips in the big blind, where the normal blind was 100/200. A guy "raised" from 1st, trying to bet the pot, but the "pot" in this situation assumes the bb is actually 200, not 50...so he makes it 350 but is forced to make it 400, the rock calls, I pot it with AA. Everyone but the rock folds. The flop is A33. Looks great, right? The rock checks, I pot it, he calls. The turn is a 9. The rock checks, I pot it again, he minraises me....great. The river is a 4. The rock pots it, I push and he calls with 33. So...I get screwed down to 8000 or so. I managed to hold on until the 8th level by restealing from this same idiot to my right. Eventually he raises from 1st, I pot it with KK, which is about 1/2 of my stack, and he pushes with AQ. Obviously he hits an A so I lose. I really hate how I can play good all day just to get in against a 3 outer and lose. So...Im not going to play any more events besides the limit shootout in 2 days and the main event. Im tired of playing good all day just to lose. Im probably just going to grind sngs hard for the next few days. Ill post again when something happens.
