I was already ITM, this was a 180 man sng at pokerstars, 11 people were left, I figured this was a coinflip situation, and i was trying to set myself up to win the tourney. good payouts dont really start till about 5th place. Should I have just pushed preflop? I didnt really like my position, and If I had a call, then a push afterwards, or someone pushing then someone else calling, i could still get away from the hand, but I was planning on calling an all in preflop agaisnt one other person.
