Subject: Unusual Mate in 3

Author: Charles Roberson

Date: 21:26:08 03/01/06


  Came across this position by accident browsing chess club web sites.
  It comes from the Duke University Chess Club. The position is
  1r5k/4NP1b/7K/8/6R1/8/8/8 w - - 0 1

  Telepath found the mate in 4 but could not find the mate in 3.
  After some debugging I found out why!!!

  Just before the final ply in the mate in 3, Telepath announced insufficent
  material which is true. But in this position you can mate with insufficient
  material.

  It put such a smile on my face, I had to share it.

  Maybe some of you have the same logic flaw in your code.
