ahand came up during the 550 event here that i am wondering peoples opinions on it. starting stack 4k we are about 50 min into tourney(40 min levels) i had been bullying the table and built my stack up 2 about 8k. i have played with villian in the past and he knows how to play but not the best player i have ever played with.blinds are 50-100.im in the small blind villian rasies to 400 from middle position everyone folds to me and i have AK off in the sb i flat call the raise as does the big blind. pot is 1200 preflop. flop comes down A 8 2 rainbow i check hoping to hide my hand and raise original raiser everyone else also checks. turn 7 complete rainbow. i lead for 700 big blind folds villian shoves for 2800. thoughts on what to do?
