This is my first post and im fairly new to the mtt world so be patient please. We are in the final 20 ish people of a small buy in tournament when this hand occurs. Both in the top 10 of chips. I didnt have many reads on the opponent other than his stats. I would appreciate peoples opinions on this as to what they would have done given this scenario.
