In this fun filled game against Nomoeo, a computer playing program on the Internet Chess Club, it seems that the computer realizes it's mate in one by making one of two forced moves for his Black king.

What's interesting for this game is that it was played at fifteen minutes standard and the rating for Nomoeo at that time was around 2200. This game was played around April 2007 and at that time ICC has just plugged in Nomoeo and since then , I'm sure ICC has tweaked Nomoeo so that a Class D player like myself could not pull another upset like this.
The second chess diagram is a " what if scenario" concerning an improvement on Black's 17th move b6 trying to chase away White's knight. It seems an improvement on that move just delays the chess computer's death.
