Call this river UI?

[sweetjazz]

Very easy call, even though you'll lose a lot. The fact that the board counterfeited two worse aces up hands makes this call very easy. Without that, you could fold with a read, but I generally would just show this down. I think you'll see a crazy bluff or some such enough to justify a call, if the player is a general LAG, but your specific read may or may not support this.
