New Pin Theory, Redemption

Submitted by sam_musil on Sun, 08/23/2009 at 1:07am.

This week, I posted 6 wins and 1 loss, so I have selected the most important win from a theoretical point and from a final standings point in the Sicilian Pin thematic tourney.  This win defeated the #2 player on the leaderboard, THCCKINGJON, who had crushed me with the white pieces in this tourney by playing the weak novelty 6. Qf3!? which took me totally out of my personal book and the master DB since no master game had ever featured this weak move.  I reacted with contempt thinking that Jon was a "patzer" and castled right into a mating attack which resulted in my second defeat in this tourney.  I had to spend 3 days doing post-mortem analysis after the game to find the right line.

Fortunately, this game Jon had the black pieces, so I did not have to worry about 6. Qf3.  However, Jon springs another innovation in the Exchange Sac Variation of the Sicilian Pin with 11. .. f6!?  This time, I knew that Jon was a strong player as he had established a strong #2 position on the leaderboard with 13 wins, 2 draws, and only 2 losses (14 points) with only our game unfinished.  I had 12 wins, no draws, and 2 losses with just 4 games to go, so a loss here would give Jon undisputed second place behind the marvelous Marjan Lacic, a fantastic Pin player that I personally love to play, but have NEVER beaten. Marjan had already been guaranteed first place long before this game concluded by winning 17 straight games with no defeats and no draws!  Only his game with me remains unfinished at this time.  But if I could win with white against Jon, that would give him 3 losses and I would have a good chance for the second place medal.  The game was very tense and Jon resigns with chances of counter-play still left, so I give the Chess.com analysis of the final position.  This defeat of Jon means that I need just one and one-half points out of my three unfinished games to gain second place and win the silver medal!  Enjoy!

sam, the Chess.com computer analysis is much worse than 2500 as fas as I know. Maybe it's about 2200 ELO (as I think Chess.com claims), but even that seems too high for the output it gives. Analyzing it yourself or analyzing it with a good engine like Rybka will get you much better analysis.

Wejerin,

I do not understand the Chess.com computer analysis and I think that it is very weak , so I am going to replace it with my own analysis!

Thanks for the feedback!  I have to review my game notes and re-construct my analysis to tell my version of the truth.  I promise that it will be more accurate than the Chess.com 2500 analysis!

26.  Nd4 appears to be a horrible blunder for white...at the point in which he resigned it seems that white had an advantage, but in the final position of analysis it seems the tables have turned...Rc4 looks like an even better move than h5.

Phobetor ,

I have not read that book, but I will certainly look at your suggestion.  I have always felt that the best way to refute a gambit is to accept it .  I have never lost a game with white to the Exchange Sac Variation simply because if I MAKE A SLIP, the material advantage obtained from the opening still insures a draw.  I have played dozens of games against this variation with no losses and just a few draws.  If I play one more draw against Marjan Lacic , I will definitely try your suggestion!

In Experts vs. the Sicilian 2nd Edition (which is a very good but not perfect book) I think the author of the Sicilian Pin chapter recommends 9. h4 instead of 9. Bxf8, which seems very sensible to me. By playing 9. h4 first, white prevents the response ...h5 and so white will be able to play h5 soon with a strong attack. I'm not sure about the exact lines, but have you considered this variation? Or do you have reasons to prefer 9. Bxf8 over 9. h4?

Don3,

Thank you so much for your compliments.  I appreciate positive feedback so much. I have many young chess players that are on my friends list and that regularly follow my blog.  I am trying to improve five different areas:  their results , their knowledge of opening theory , their knowledge of the history of each opening , their analytical ability , AND their love for the beauty of chess and the richness of these variations!  If I touch each of these areas every week , then I have succeeded in reaching my personal goals for this blog and sharing my love for this great game!

Your humble instructor,  Sam
