every decsion you make at this point will be for your stack !!! you need to be looking for soild spots to jam. a good foundation on icm really helps here. very important to maintain your fe at this point and good hands to open hoping to get reshoved on or squeezed when u have a premuim. because you should never be raise folding this stack size and hands to 3 bet reshove hands that flop well ect almost anything playable i dont like my stack getting much smaller.very important to not miss any spots at this point, this is for the 15 bbs if u had 28,828= 27 bbish  im def opening late postion. still looking for key spots and looking to pound on the tighter players ect , 27 bbs huge key is watch your bet sizing really important. i watch so many players stick there arm out there with there pre bets and they end up getting it chopped off , when opening i like 2.5 x this is just me but i see so many put to much in the pot then they really can fold ect , and i think 27bbs you can raise fold.
