So here 50BB deep I think I made a mistake. My 4bet seems too big... if he 5bets he can only shove so I think I should size down to at most 100-110k. His 3bet was on the smaller side too and its BU vs CO range (he should be wider). On the other hand I would be giving him too good of a price to call with JTs etc. I know it's a really small difference but 20k here 20k there could be a stack and will help me apply the thinking process on similar situations.
