flat calling an all-in vs. reraising
 

This is something I've been thinking about a while. Here's the situation: a small stack goes all-in before you and it's somewhere between 10-25% of your stack. Assuming you're not folding, what are the factors (number of players behind you, their stack sizes, your actual hand, etc.) that will make you lean toward flat calling vs. reraising?

I find that I almost never flat call here and I'm wondering if that's right. What are others' thoughts?

You should almost always raise or fold. A call doesn't make much sense. You invite other people into the hand, which is unlikely to be what you want.

A pot-sized raise makes it unattractive for anyone to call. A very good hand will raise again, so you can fold unless you think it's a bluff. Most hands will fold because it's hard to have decent pot odds in this situation. So you'll force out all the others and get your heads up all-in with the small stack.

It depends.
If the opening raiser makes continuation bets, never flat call.
If the opening raiser only bets the flop when he has something, flat calling is okay.

You have the big database. Check it out.

More or less what everyone else said. Maybe if you are very lucky and have AA/KK and it leans more toward 20-25% of your stack rather than 10%, then maybe flat-call, trying to let someone get enough to give you their stack as well. Even then, only maybe.
