10/4/2020 Two days ago, October 2, it was Jon Speelmans 64th birthday. Given that 64 is a canonical number for chess players, our columnist used this chance to remind us that every single square of the chessboard may be important. In order to illustrate his point, he goes on to show a game in which, as Black, he placed his knights on both h1 and a8 during a single game. Happy birthday, Jon! And many thanks for your ever-ingenious columns! | Pictured: Speelman usin PressTel Chessbox to play long distance chess | Source: British Chess News

Im writing this on Friday, October 2nd which, a fond hope, is International Day of Non-Violence after Gandhis birth on October 2nd 1869, and coincidentally (there are lots of worse people to share a birthday with) my own. Mercifully it isnt a round one, at least for a pentadactyl, though if our lords and silicon masters eventually attain real consciousness, they will presumably consider 0x40to be fairly round and their more simple-minded colleagues will deem 1000000 to be very much so...

Im not enormously delighted to be 64, but at least it is a canonical number for a chess player and does provide a fairly plausible segue to the idea that every single square of the chess board may be important (or to misquote Monty Python: Every square is sacred).

Theres a game I sometimes show people in which as Black I put knights on both h1 and later a8,and it appears at the end. (I think it may have appeared here before but not for a good while?). This set me thinking about how unusual it is for knights to appear on multiple corners of the board in the same game, and I did a fairly simple-minded search for white knights on a1 and h1, starting by making a database of games in Megabase in which a white knight at some stage appeared on a1 there were a little over 17,000 of these and thensearching that database for ones in which a knight also appeared on h1.

These are pretty rareand, of the nearly 6.5 million games in my Megabase,I found 39.They included three in which people (kids?) had agreed a draw and then moved their horses around the board for a longer or shorter time: one of these masterpiecesended in the initial position (admittedly after rooks had also moved, so in no-castling chess) after Blacks 54th move. There were also a few instances of Chess960, but still over 30 real games.

After a quick look at these, I reached a tentative conclusion that knights on the rim really are dim or at least that the people who had created this very aesthetic picture were making a minus score. To my surprise I also found that of these 30 or so games, eight (!) featured white knights on a1 and h1 at the same time.

Given a chance to create such an aesthetic picture, Id certainly do so myself if the second knight move to the corner was decent, but I dont think that aesthetics played any part in most of these, and you can judge for yourselves.

I realize that foolish horses in the corner may not be to everybodys taste so please dokeep on sending in your Agonizing and Ecstatic games and /or ideas for future columns, more rooted in the nitty-gritty of battle.Readers whose games or ideas are used will win a 3-month premium membership.
