Finished one place out of the money last night. Played tight aggressive all night and did well. Final hand with 4 players left, me against the chipleader, blinds at 400/800 I am on the button and he is in the big blind. I have A 10 and raise to 2800. He calls and flop comes xAx, he is first to act and ask me how many chips I have left. I told him had me covered and if he wanted me all in just say so and we can count them down after we see the rest of the cards. He fooking puts me all in and turns over KQo wtf? Turn card K, river card Q

wtf?
Oh well I still had fun.
btw, on raising with A10, we were down to 4, I had been playing tight, I was trying to pick up the blinds, he had shown us too many cards after big raises like A2 and K4. I thought at the time it was the right call.
