Hey guys I've started grinding low stakes online (mtts and sngs) to biuld a roll for mtts . I've noticed specially in sats that when I get to the bubble or near the money most of the time I dont have a big stack I assume that I am missing a lot of shoves specially spots where i should be shoving atc , maybe gamble more in certain spots in order to be a favourite to make the money.

Could anyone help me out so i can improve this?

Thanks!!
