Sorry, maybe you're right & apologies for taking up space in a very helpful thread

"This example is like purposefully betting bigger on the flop to guarantee you have odds to call a push. I think that is throwing good money after bad." - For me that is a huge mistake - you're right - but its a completely different kettle of fish.

I still think my argument "with a smaller starting stack you need considerably less equity on the flop vs his range to get it all in profitably after 4-betting pre." is true.

I'll try use a more realistic example if that will help.
We'll assign this aggressive villian a 4bet calling range of 88+, AQo +, (for the example.)

Hero - A8o
Hero raises to $4, Villian raises to $12, Hero raises to $34

Flop AJT Pot - $70,
a)villian shoves, hero has $26 behind (60bb starting stack)
b)villian bets $45 , hero has $66 behind (100bb starting stack)


With 32% equity vs this range, the call seems right in a but in b it becomes a tricky spot.

(Also when you 4bet villian has to call +- 20$ more & he is getting about 10-1 odds (with 100bb stacks) assuming all the money is going in often post flop, making it almost +ev to set hunt and call with some speculative hands but when you 4bet with only a 60bb he is only getting 6-1 on his call even if all the money goes in post flop so he is making a big mistake if he calls with anything speculative.)

Again I'm also just looking to learn sorry if any of this is incorrect/defensive.
