Depends, if you're short stack you go all in with what the nash chart says, it's mathematically solved. If you are deep, you can shove oop with premium
hands, but sometimes you will most likely call 3 bets/4bets. So if you have AK oop, you can decide to shove, up to 100 deep, you will usually be flipping, but it's better thn having a though spot and being denied
equity. IP you will most likely call, you will be able to
bluff, slowplay or value. 150bb deep or more, usually be playing postflop, shoving is possible, there re some 4 bet light that you want to call to let him bluff at least on the flop, to win a max, better to do that deep enough and IP.
