Hey guys this is my first post on here so any suggestions would be great. This is final table of a $10 mtt on stars.

The villain in question is an established reg and the best player at the table, vp20 pr15 3b6. The rest of the table i believe to have an edge over, mostly nitty regs and nitty fish.

His 6% 3b is not completely accurate as i know his style with the big chip stack at ft is to apply pressure. I have already seen him 3b, fold twice. I believe he is going to be 3 betting a bunch more than top 6% in this situation. Especially with position and against myself with an awkward stack size. Is there any merit to just calling the 3 bet oop against his wider range and reavaluate on the flop? Once i 4 bet im commited, right? His 5 bet shoving range is aqs, ak 10s+.

Its a pretty standard situation to just get it in here for most people i know, just wanted to know with icm considerations i should play the hand differently. To be completely honest i dont really understand how icm should change your decision making process. I undersand the basics but get a bit muddled with specific situations.
