Wikipedia can have some nice surprises, such as this detailed entry on the Monty Hall Problem:

http://en.wikipedia.org/wiki/Monty_Hall_Problem

This relates to the bridge "restricted choice" problem, and the Wikipedia article even refers to Phil Martin’s Bridge Today article "The Monty Hall Trap", reprinted in the book "For Experts Only" - and Steve Bloom in a later part of the book calls it a "beautiful article" - the book article caption is "Information that the opponents give you is not the same as information you discover yourself". Put another way, information "Monty gives you is not the same as information you find out yourself", as you can discover from the Wikipedia link.
