40 Move Challenge

Game Of The Week


This week's game comes from the Colorado Springs Chess Club's event:  CSCC Honorary Medal Rapid Online (4SS, G/10+10).  It was played by Jose Llacza and Paul Anderson.

I picked this game to publish because it was the end of my 40 move challenge.  Sort of.

The 40 Move Challenge is a LM Brian Wall creation.  He may have written about the history and rules in his emails.  However, since Yahoo! killed their archive of his emails, it is hard to find any details about things he has written online.  I did run across his book, How To Play Chess Like An Animal, on Amazon, which has increased in value dramatically.  I may have to start an account and sell my copy as the paperback is currently listed for:  2 Used from $902.81, and 1 New from $809.67!

Without the actual rules for the 40 Move Challenge, I just did my own thing in the Colorado Springs Chess Club's Sunday Night Corona Olympics. 

We meet every Sunday Night at 7pm Mountain on for a couple hours since the Coronavirus has shuttered the physical location.  I never thought we'd be closed this long and needed something to amuse myself.  The 40 Move Challenge seemed just like the remedy for my quarantine hangover.

My goal was to play all 40 possible opening moves for White and Black before my chess blogging season ended.  I failed.

I just made a list of all the moves and tried to play them in order.  This is difficult when you are on the b5 opening and your opponent plays 1. e4.  So, I skipped a couple moves here and there, and came back to them when I could.

Another problem was we didn't always get 4 rounds for our events, and I came up 2 games short of my goal.  I also got paired as White 22 times versus 16 times as Black.  So, I replayed 2 White openings I lost (winning the second time) and didn't play any Black Knight openings.

I scored 22.5 points out of 38 games for a winning percentage of 59.21%.  However, I was surprised to see where the wins came from.  I did the best with Black's King Pawns (75%) and worst with the Knight openings (12.50%).

The challenge made the online events more interesting, as I had to focus from move one, and it was thrilling to finally get to play b5 and g5 without being down a Pawn (and winning too).
