If we're getting it in all in here by 4betting, then calling to induce a squeeze by MP2 can't be bad because then it'll just increase his range and your equity. If you're unknown then they could just as easily think you're a donk too and your hand wont be faceup.

Folding seems to be the worst play IMO and saying to do it just so you can avoid playing in a tough spot seems to be the wrong reason. If you think you're behind then you can set mine because you're getting the odds; otherwise you're ahead and you should still play it and folding would be an even worse mistake.

I guess I just don't get the reason that since we don't know if we're ahead or behind then we should just take the easy way out and fold.
