Why does it matter if we're 200bb deep if we're folding a monster when he makes a stupid overbet shove? That's where I'm lost.

If the bottom of villain's range here is 9x, then yeah I obviously see why we're folding. But I've done this with AK twice recently, stupid fucking shove thinking I can push villain off his hand. And I'm still beating 25nl, despite my tendancy to spew now and then. This is a losing 10nl player, at least I assume he is with these stats. That's why I think this isn't the fucking nuts only. Oh, and this...

He doesn't raise a ton, however he's played like nearly 40% of hands..limp/calls a ton preflop etc..
How often does he have 33 and 97? 33 like never, that's standard l/c territory for a limp donkey. And 97 is a stretch.

Sorry if I'm taking a lot of convincing here, this just doesn't make any sense to me and as such I'm looking him up, expecting spew a lot more often than better. Maybe when I have more experience like those of you advocating a fold I'll realise it's a bad call, I guess sometimes you have to learn the hard way.
