Ever worth p/f to call an all-in with a small pair?
I started wondering this when I saw this:
Hero is dealt 77, raises 2.5 BB from hijack, all fold to BB (short stack, but blinds aren't exactly devouring him) who goes all-in for 4/5 hero's stack, all fold to hero.
40% elected to call here, and I've seen a similar call advocated several times before.
I honestly can't imagine a player type that in the long run this play pays off against, even if as in the example above, you can be certain that you will be heads up.
My reasoning: we should always expect to be up against at least A-<7 (which would be all right), but more likely a higher PP (in which case we're toast) or two overcards (in which case we're not quite comfortable). We also have very low flush or straight odds
Am I overlooking something (obvious)?
Would having x times the stack size make these calls more worthwhile?
Thoughts much appreciated
