40 Move Challenge, Part II

Game Of The Week


This week's game comes from my database of 1,030 standard-rated, USCF games.  The database came to an abrupt halt on March 10, 2020 after my 42nd win over Mark "The Money-Man" McGough.  Then the club was shut down.

Mark is the Treasurer of the Colorado Springs Chess Club and my most frequent opponent since 2010.  We have been working to get the Acacia Ballroom back open, but the Housing Authority controls the space and does not seem to be in any hurry to re-open.  I guess they don't need our pittance of rent.  So, we are looking into going back to off-site venues like the club did in the past.

One site where we played was Dean Brown's events on the Air Force Academy.  Mark and I first faced each other at those events (USAFA NoEF Quads #2  2010).  He got the first win and jumped out to a +3-2 game lead.  However, I have caught up since then.

Anyway, the reason I was looking at my database was to see if I had ever played the Polish (1. b4).

I am doing another season of my take on LM Brian Wall's 40 Move Challenge.  The idea is to win with every legal opening move.  Initially, I thought I could get it done in a couple of months.  However, it was much harder than I thought.  You don't always get 4 rounds each week if turnout is light.  Also, the Renaissance Festival re-opened this year, and I missed a bunch of events to play chess as a Monk.

The last move I had to complete was 1. b4 since I had drawn it against Vedant Margle in March.  Finally, this week, I won my first-round game with the Polish and finished my second season of the #40MC!

Now, I could look at the numbers and see how I did.  A perfect score would be 40 attempts and 100%.  However, I have a lot more room for improvement on Openings to hit that milestone.  I am just glad to see I improved over last year by finishing in 10 less attempts.  My Achilles heel was with the Black King Pawns this year.

One of the nice things about these Irregular Openings is that they can throw your opponent off his habitual pattern recognition and create early mistakes, especially in Rapid time control.  My game this week went that way:

1. b4 e5 2. Bb2 Bxb4 3. Bxe5 Nc6 4. Bxg7

Of course, I knew I was playing something unfamiliar to myself and had drawn it the last time.  Also, I wanted to get this year's challenge completed.  So, I was taking my time and posted a 98.5% accuracy score and the game was never in question, which is nice for getting past the challenge but not nice for having a tactic for the blog.

However, the database revealed that I had played one game that started 1. b4.  Jerry Maier used to direct tournaments for the club and threw the Polish at me.  I avoided any early blunders from the shock factor but missed a tactic in this position.

This Week In Chess


On August 15th, the Colorado Springs Chess Club held the Bad Habits Rapid Online (4SS, G/10+10).  The top five players went unbeaten.  LM Brian Wall and Alex Bozenoff sat out a round to take themselves out of medal contention.  So, the top three went to tiebreaks to decide who got which medal.  Andy Rea played the toughest competition to win gold, Paul Anderson took an easier path to the silver, and Brian Rountree had to settle for the bronze.
