Villain offers to show a card

[pococurante]

Can't really fold top two here. Move all in and hope you're still good.

IMO the villain offering to show a card is a sign of weakness. If he was that strong, he would shut up and let you get all in against him. He could easily have an overpair, or a worse two pair. Gotta call here.

Also, consider this: suppose you buy a card for $30, and he shows an ace. You then push all in, and he folds. Result = he keeps $160 that should have been yours, and you paid him $30 to do it.
