An unpleasant overcall.

[drzen]

Grunch.

Cap the flop. Fold the river. May Ed Miller have mercy on my soul but if I'm not beat here, I don't know when I'm ever going to be. MP could have nothing much but SB has to have hit the flop with your read.

What odds would I want to call it? A big enough pot would have meant more action on flop and turn, so I'd be even surer I was beat here. But I don't think I'd ever fold a pot, even if I was absolutely sure I was beaten, that offered 20 to 1 for a single bet.
