It sounds like the bottom of your shoving range vs. the v bottom of his calling range, I would fold here, even short handed, especially if the blind was a lag and had me covered. The hands he calls with here are almost always going to be on top to a certain degree, I think only that special lag would call with low suited connectors. But would call with a baby ace and at that point your at best a coin flip. And I forget who said it, but someone once said that just because a situation is plus ev doesn't mean its always right. And let's say theoretically that you fold here and float down to 5 BB with 5 players, you get, what?roughly 20 more hands to shoot with. The hands he folds to your shove and win the blinds and antes uncontested vs how many times he will call and you actually win. Because in my eyes, you lose that flip a lot of times because of his calling range vs your hand.
