On Axs, more limpers = better. Good if you flop the hotness (flush/draw, 2 pair, 3 of a kind, bicycle straight etc). All in all that's about 1/8. So to justify the call you need about 3-5 limpers, and at least 1 caller to a pot-sized bet after the flop when you hit your hand (this makes 8x your blinds). I wouldn't play this hand if it's folded to you.

More limpers in this situation.
