A Game That Outlasted the Day (3)

by ChessBase
4/6/2026 – Two months ago Valery Golubenko played what may well have been one of the longest chess games ever seen, measured by number of moves, under the rather restrictive conditions of modern chess life. At move 88, with queen and b-pawn against queen, Golubenko's opponent held for 37 moves, until he missed an only move, and it was theoretically a mate in 47. | Photo during the game by Chess Club Kaksikodad – from the right, GM Aleksandr Volodin and the chief arbiter Askold Nassar

The Longest Game

By Valery Golubenko

This time I will carry out a detailed analysis of the endgame "queen and knight pawn versus queen" that arose on move 88 of my game against Kirill Gorkov (Estonian Team Championship, Tallinn 2026). I will try to understand why it was theoretically drawn for such a long time, at first from move 88 to move 125, and then in different circumstances.

After each move, starting from move 88 and ending with move 228, I will indicate the number of moves required for Black to deliver mate, or leave it blank — this will mean that the position is theoretically drawn (which for instance is the case from move 88 to 149, except for moves 125-126).

Readers will find it interesting to follow how the numbers change: if after Black's move the number does not decrease by 1, this means that Black is playing inaccurately (and the greater the difference, the more inaccurate the play); if after White's move the number decreases, this means that White is playing inaccurately (and the larger the decrease, the more inaccurate White's play); if after White's move the number remains the same, this means that White is defending in the most stubborn and resilient way. As you may already have guessed, after Black's move this number cannot decrease by 2 or more, and after White's move it cannot increase even by 1.

Let us look now at the final position, in which Black (that is me!) wins, but was prevented from doing so by the seventy-five-move rule.

I vaguely remembered that in queen-versus-knight-pawn endgames, the queen should be placed on the central diagonal — but I could not recall whether this should be on my own side of the board or my opponent's. I failed to find a detailed analysis of this endgame in Mark Dvoretsky's excellent manual (I own the 2017 edition), but the analysis of this game makes one thing absolutely clear: the queen belongs on your own side of the board — on e5!

With the help of the Nalimov tablebases I discovered that the final position is mate in 39 — and how devilishly difficult this win really is.

On March 9th 2026, on Fischer's birthday, which isvery memorable to me, I submitted an application to Guinness World Records. For the time being, I will keep the exact category confidential, but I am absolutely convinced that at the present moment, under today's draconian time controls and the restrictions laid down in the current FIDE Laws of Chess, the game Gorkov– Golubenko is the longest classical tournament chess game ever played in terms of number of moves.

Unlike other long games in the entire history of world chess, this game did not result in the dull drawish endgame of R+B vs R, which was studied yet by Philidor more than 275 years ago. It was filled with intense struggle until the very last, 228th move, and ended only due to the automatic 75-move rule in a winning endgame for Black, which is still little studied and remains extraordinarily complex even for the stronger side. Or not so little now?

Grandmaster Dr. Karsten Müller, one of the world’s leading endgame experts, guides you step by step through everything you need to know in this second volume.
Picture this: you’ve outplayed your opponent move by move, you’re clearly better – and then the endgame slips into a draw, simply because you lacked the crucial theoretical knowledge. That is exactly where this course comes in. Without solid endgame skills, there’s no way forward. Rook endgames are most essential: they occur more often than any other type of endgame, and often make the difference between victory and half a point. If you master them, you’ll confidently convert your advantages into wins!
