Daily Chess Puzzle

Today’s problem is from an old edition of Chess Magazine. I don’t know which one, because, as is my habit, from time to time I photocopy a page to solve on walks or on trains etc; and my copy doesn’t show the magazine date.

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.

 

White to play

 

 

Iturrizaga Bonelli Eduardo - Warmerdam Max (36.exf3)

Iturrizaga Bonelli v Warmerdam, Vlissingen, 9/8/2018

 

Solution

This took me a couple of sittings to solve, but, when I got the light-bulb moment, it was a moment of pleasure.

1 Nc6! disrupts Black’s counterplay sufficiently that Black is overpowered, typically by Qg5+.

White to play

You can tell from the Chessbase evaluation that “something happened”. Aronian missed something in the position below.

Capture

Aronian Levon - Nakamura Hikaru (29...Rc4)

Aronian v Nakamura, Saint Louis Rapid 12/8/2018

Solution

I doubt I would ever, not even in a month of Sunday’s, have played the move Levon missed: 1 c3; Komodo gives it as the only move which gives a winning advantage; all other moves, including Levon’s 1 d7, losing.

Aronian Levon - Nakamura Hikaru (30.c3).jpg

1 d7 lost to 1…Rb4; from this can be seen that 1 c3 is “simple” prophylaxis. If Black doesn’t mate White, e.g if he plays 1…Bc3 2 Nc3 Rc3, then 3 d7 and the pawn queens, since 3…Nf6 loses to 4 Qg7 mate.

Black to play and draw

 

Arkell Keith C - Toma Katarzyna (54.Nd4)

K Arkell v K Toma, Hull 30/7/2018

Solution

In the game, Black played 1…Kf7 and lost; a typical Arkell endgame grind.

I struggled (failed) this one: trying to make 1…Be4 or 1…g5 a draw, without success.

But 1…Ke7 is a draw: I don’t really know how/why, but having played around with a few lines, can just about see that it is. The engines are their unhelpful best selves, showing 0.00 as tablebase outcomes.

Arkell Keith C - Toma Katarzyna (54...Ke7)

(Having spent a good while on this puzzle, I am not much the wiser. It seems to be just a matter of calculation; after 1…Ke7, 2 e5+ can be met by 2…Bc6+ pushing the k away; whereas if 1…Kf7 2 e5+ then 2…Ba6+ is met by 3 Kd6).

White to play

Kulaots Kaido - Gu Xiaobing (21...Kh8)

 

K Kulaots v Gu Xiaobing, Hastings 6/1/2013

 

Solution

1 Bh6! is the key, the move you more or less have to play. ┬áBlack can’t capture it, so 1…Ne8 or 1…Nh5 are the only choices.

Kulaots Kaido - Gu Xiaobing (22.Bh6)

The lines are a true forest; I have spent a long while working through Black’s many defences (1…Ne8 2 Rg7! being best, but there is still a fight); one for any readers who are interested to self-study.

White to play

Yang Darwin - Kiewra Keaton F (17...Bb4)

 

D Yang v K Kiewra, Los Angeles 21/12/2012

Solution

Since it is a puzzle, 1 Re6! is the first move to be thought of, and, sure enough, it wins.

After 1…Re6 2 Nd5 Nc6 3 Qg4

Yang Darwin - Kiewra Keaton F (20.Qg4).jpg

White is winning; Black has several defences, non sufficient. In some lines, the LPDO Qd7 is the end point of tactics; other times, Nf6+ is a discovered check and mate.

Ansell Simon - Rowson Jonathan (15...Ne5)

 

S Ansell v J Rowson, London 4/12/2012

Solution

This puzzle took me several sittings; in the game, White played 1 Bf4, the obvious move, and has a slight advantage.

But eventually I found 1 Qe5! Be5 2 g4

Ansell Simon - Rowson Jonathan (17.g4).jpg

2…Bb2! 3 Bb2 Qd5[] 4 Rd5[] ed[]

Ansell Simon - Rowson Jonathan (19...exd5)

And I just about assessed this position as better for White, though to be honest, “anyone’s game” is more my judgment. Komodo thinks White is about +1

Black to play

Maze Sebastien - Gharamian Tigran (34.Kxf5)

 

S Maze v T Gharamian, Nimes 23/8/2018

Solution

1…Rf1+! diverts the Bg2 from the long diagonal; White resigned.

Maze Sebastien - Gharamian Tigran (34...Rf1+)

 

If 2 Rf1, then 2…Qe4+ 3 Kf6[] Qe6 mate.
