Daily Chess Puzzle: AlphaDubov

Today’s problem is from the current European Team Championships.

As is my custom, I only say which side is to play: and not giving an idea if the move wins or otherwise, unless on occasion I think signposting would be helpful. Instead, the problems are posed with the instruction to decide what you would play, as in a game.

 

Black to play

Daniil Dubov v Rasmus Svane, European Team Championships, Batumi, Georgia, 31st October 2019

Solution

Black of course played what any human would do (except maybe the elite players?!) 1…Kc6. Komodo immediately switches to mate in 13…which more or less Daniil Dubov found, in this contender for game of the year.

But apparently 1…Qe6 is more or less equal: though that is just from a few minutes of exploration. It seems that White only has Q and R and a phalanx of pawns; with Black able to hold their advance by Rf8; and then Black’s g pawn distracts White’s rook.

The game is well worth studying. Earlier in the game, it looked like AlphaZero style:

Daniil Dubov v Rasmus Svane, European Team Championships, Batumi, Georgia, 31st October 2019

Solution

A position for a contender for game of the year. The end of a king hunt. Very apt for bonfire night.

1 Bb3!!! []

The only move to win.

Dubov Daniil - Svane Rasmus (36.Bb3)

1…Bd7 (1…Kb3 2 Qc2+ and 3 Qa2 mate) 2 Qc1+ and mate by 3 Qc2+ and 4 Qa2.

Sportingly, Black allowed mate.

Jones Gawain C B - Onischuk Vladimir (25...gxf6)

 

Gawain Jones v Vladimir Onischuk European Team Championships, Batumi, Georgia, 28th October 2019

Solution

“Bring all pieces to the party”

Gawain added one more piece to the attack by the rook lift 1 Rb4!: better than Rf1, since the rook can swing to g4, hitting the Q whilst defending g2.

Jones Gawain C B - Onischuk Vladimir (26.Rb4)

Black resigned a few moves later: 1…f5 2 Bf5 Rg8 3 Rg4! Qf7 4 Rg5 Be8 5 h3 Rg8? 6 Be6 1-0.

Jones Gawain C B - Onischuk Vladimir (31.Be6)

The whole game is worth playing through, to see the way in which Gawain built his attack.

Mike Taylor v Nick Lowe, Stockport v Altrincham, Bramhall, 30th October 2019

Solution

1 Rb7! with the nice point that if 1…Nb7, 2 a7! promotes.

Pos180

 

Black played instead 1..Kc8, permitting 2 Re7, the a pawn advanced, and soon the Pc6 fell, 1-0.

The tricky side-step of the N, rather than the automatic capture 2 ab? was a nice point spotted by Mike.
