Donk of death the river?

[MitchL]

It never ceases to amaze me what passive live players will check behind with on the river. A couple of months ago in the Bellagio 30 I had set over set 2x (1 time I had the over and the other the under), both times they checked behind neither time was the board at all scary, i.e. the nut hands would make no sense given the action. I have sworn off trying to cr loose passives on the river.
