Barnet chess club on-line has enjoyed being part of this unique game, and hope that new chess players emerge from all around the world as a result of the interest it has created! Best wishes to you all ! 10/10/1999 The Queen and pawn ending is examined. A draw seems likely. 13/09/1999 The queen endings are not without interest. There are bearer "trunks" of variations, but interesting logical and predictable plans. The endgame in chess may not be as boring as commonly thought by many players!! 12/09/1999 Moves played added. Interesting queen endings can arise now. 31/08/1999 36..Kd5 made main line as of game, and some lines added. 30/08/ 1999 36...Bc3 (GM Suttles) seems to be the strongest move. Kd5 seems to lose because of g5 followed by h6, then Rd1 with the threat of Be3. By the power of Aron Nimzovich, we can blockade Kasparov's dangerous passed pawns! There are at least three valid ways of blockading/ threatening to wipe out Kasparov's pawns which are now encapsulated in the variations added. Be positive World! We need to find the ABSOLUTE BEST resources in the position! 29/08/99 Kasparov shocks the world with an unexpected Kings move - Kh1. It unfortunately looks very strong, as it simply reduces black's counterplay and facilitates the 2 passed pawns march. 28/06/99 More endgame analysis added- The "King walk to g6 followed by h6-h7, Bh6-g7 variation" looks very dangerous unfortunately. 27/08/ 99 Barnet's computer resources have been upgraded!! Please welcome mean machine Hiarcs 7. 32, arguably the strongest PC based chess program. This replaces Crafty. Critical and fascinating endgame analysis has been added. Kasparov has many situations where he has apparently deadly looking connected passed pawns, and there is a very delicate balance against Black's counterplay. The Black King plays a pivotal role in variations now! Please enjoy! 19/08/99 Some critical variations examined after the World's repsonse to Qf5+, ie Qe6 14/08/99 13:06 GMT 29... b4 does not look so bad! Some very interesting positions result ! 14/ 08/99 Variations involving a simple and direct Kasparov plan of h4-h5. The world has interesting resources however! 09/ 08/ 1999 Qf7 as played by Kasparov promoted as main line 07/ 08/ 1999 Analysis by Peter Spiriev added. If this analysis is not fundamentally flawed, the World could be in danger after 25 Bd2 :-( 05/08/ 1999 more variations added 25. ..b5 looks good for the World! Go World! 30/7/ 1999 More lines added to analyse Kasparov's possible response to 20..Be5 28/7/ 1999 Some more analysis for what to do against Bg5 added 27/7/1999 Kasparov plays a simple and effective move Bg5 against the worlds f5. Some lines of analysis have been added related to this move. 25/7/ 1999 20:00 GMT. Whats new!: f5! in response to Qb3 added! Congratulations to GM Chess School for this innovation. The lines presented in this analysis need to have more evaluations but f5 seems very promising! 25/7/ 1999 Added more variations for 18 Ra3. This is variations analysis provided by Barnet chess club, a chess club in North London, England, United Kingdom. Barnet chess club has some very strong players who have beaten IM's and occasionally held a draw against GM's! They also have some connections with strong IM's and GM's which can be reeled in to help analysis of this great game!
