Alright, basically here's the deal. I have JJ with 12BB (slightly below average stack) in the SB 8-handed in a donkey live tournament. About 30 people remain. UTG shoves (he was on tilt) for about 2.5BB, UTG+1 calls (decent player). MP1 folds, MP2 folds, CO folds... I didn't see BU was still acting, and i said all-in. Players said I was acting out of turn and thus my only two choices were a call, or a fold. I ended up calling, and I said "I'm all-in blind" and shoved my chips in the pot.
Now i think this was the right move, as a decent player on the tight table would've called any top40% hand preflop, and could make a call-down with a higher pair if they paired if i showed such weakness.. what do you guys think?
