I am new to the MTTs, so not sure about those close spots in my opinion. What is the weakest hand u are open-shoving in this spot? What factors are most important to consider? I like having big stack player right to my left since on the one hand big stacks are most likely to call our open shove but with many players behind him he will play more tighter when late position players are deeper and more inclined to call.

What range does it make sense to open shove?
