Psychology of all-in
 

This may be more suited to the psychology forum, but has anyone considered the psychology of putting someone all-in? For instance, let's assume you have the nuts or near-nuts on the river and you want to get all of their stack, but you are not sure they will call off all their chips. They have $100 remaining and the pot is, say $125. Do you think there is a much larger probability that they will call a $80 bet, knowing if they lose they will still, at least, have $20 left, than they will call off the entire $100. I think there may be some psychological hangup with losing your entire stack such that there may be some merit to this idea.

depends on the player, but I'd say in general no they aren't more likely to call a $80 bet vs a $100bet allin

the times you bet 80 and they would have called 100 outnumber the times you bet 100 and they fold but would have called 80 a ton

a smaller bet could possibly have more ev, but 80 roughly equals 100 here, you just lose 20 everytime they call when you bet 80

With some people, it's actually more likely they'll call the all-in, as opposed to the nearly all-in. They may interpret the $80 bet as a calculated value bet, but the all-in may look like a bluff, with maximum folding equity. If you're putting someone nearly all in on the river, just put them all-in instead.
