Ray, that should be pretty easy, thoug, shouldn't it? You get reraised pot sized on river with top boat, just call instead of getting greedy and reraising.

I guess the difficulty comes when the preflop play has been aggressive enough to make the pot unmanageably huge...

This is one possible benefit from the half pot bet on the flop and/or turn, which I think is far too underutilized at the limits I play. People at the $25 or $50 buy in seem to either bet pot or minimum. A half pot bet at either of these spots would seriously cut the amount of the huge raise on the river...
