we are 7 out of 14 left with about 30bbs in sb with 10ss,,table is 7 handed .5th and 6th are also around 32bbs,button being chip leader with around 80 bbs opens for 2.5x .what should our most optimum play be here, 3 bet and if yes to wat sizing and what should a reaction be to a jam and also our action if flatted on jack high queen high plus boards, should we just call and look to play post flop or can we just jam for 30bbs against the chip leader here ?
