basically i'm going to 4-bet light with hands that have good equity vs his pushing range.

ok so in the above example where we 4bet to 54 and he shoves, we have to put in 146 more to win 403(ill even let you have the blinds as dead money), meaning we need 36.2% equity to call a shove.

Now people at 200nl party games usually have a 5bet range of AK/QQ+, sometimes JJ, but we can even widen that range to AQ+/TT+. seems like your 4betting range here is going to be super super tight if you like money. eg ATs is only 30% v that range.

if your never 4bet/folding you basically telling the dude your 100% allin when he only has 14% of his stack invested, makes it a very easy game for him.

edit - also 4bet folding allows you to choose whatever situation you think will gain the most fold equity in. If you have to wait for both a good situation, and a good hand vs his shoving range, then your either going to be choosing sub-optimal spots or sub-optimal hands
