An empty square!

[Note that Jon Speelman also looks at the content of the article in video format, here embedded at the end of the article.]

We start today with an incredible move which could have been played in the blitz tournament in Saint Louis. It must have been highlighted elsewhere, but I spotted it “myself”, due to the efforts of the silicon brotherhood.

There are some ideas which the meanest members of that brotherhood will flag up immediately but are way beyond our normal human compass. This is one which I couldn’t imagine ever being found in a blitz game but might be within the range of a world-class player in a classical game if not in time trouble: Vasyl Ivanchuk, say.

Please have a look, and if you do get there then perhaps you could also find the answer to the main line in which White replies with a rook move.

If you’re still wondering but haven’t checked the games file, then you might consider the title of this column. The vacuum refers to the fact that the move is to an empty square...

Master Class Vol.4: José Raúl Capablanca

He was a child prodigy and he is surrounded by legends. In his best times he was considered to be unbeatable and by many he was reckoned to be the greatest chess talent of all time: Jose Raul Capablanca, born 1888 in Havana.

Working from this, I started thinking about other unusual moves to empty squares and came up with these. The most common are queen sacrifices to create knight forks, which are lovely but fairly easy to spot once you’ve learned about them: indeed, Anish Giri took less than a second to find the one in his game.

I’ve then got the famous game Ossip Bernstein versus José Raúl Capablanca, followed by a couple of illustrative positions of my own in which White needs a deflection to create a back rank mate. In one case it works swimmingly, but in the second, after an apparently tiny tweak to the pawn structure, it fails spectacularly: a reminder that when calculating tactics you must consider all relevant details.  

This tactical exercise points back to a very famous but I suspect apocryphal game in which there is a whole series of queen sacrifices on empty squares due to a back rank weakness.

To finish, what has to be the favourite move of my life: an absurdist knight jump into an armed paddock in the heart of the enemy territory. It isn’t a knight sacrifice as such, and sadly — though very predictably — isn’t sound.  But I've certainly enjoyed having played it in retrospect, if at the time it was more of a madcap gamble.
