The new position will appear at the beginning of each new month. You are invited to solve it. I will be pleased to receive feedback about the positions and the analysis. The solution will be published the following month with the new position. Some of these positions will come from actual historical games. Others will be composed endgame studies, but they will be relevant to the practical game. The site has over 400 chess endings and endgame studies and and has been running for over eight years.

POSITION 380

White to play and WIN

FEN:5n2/8/2k4P/p1p1P3/1pK1P3/8/8/B7 w - - 0 1:

 It is good training to try initially to solve the endings without the assistance of a chess playing programme.

Solution for the above, plus new position: 1st NOVEMBER 2006.

White to play and DRAW

FEN:2K5/2Pnk1P1/PP6/8/2b5/2n5/8/8 w - - 0 1:

White has four passed pawns against the Black pieces which at a glance look overwhelming. White is fighting for a DRAW because his King is restricted by his own pawns. In advancing the pawns for promotion White has to be aware of mating attacks from the Black pieces. A recurring theme in many of the variations is the threatened mate with two Knights. Also amazingly is the series of underpromotions; Knight, Bishop and Rook that White uses in his defence against the Black pieces.

1.a7! ...

1.g8Q? Bxg8 2.a7 Bd5 3.a8Q Bxa8 4.b7 Nb5(Ne4) 5.bxa8Q Nd6 mate;

1...Ba6+

1...Ne4 2.Kb7 (if 2.a8Q?? Nd6 mate) 2...Nd6+ 3.Kc6 Ne5+ 4.Kc5 Nd7+ 5.Kd4 Nxb6 6.a8Q Nxa8 7.c8Q Nxc8 8.Kxc4=;

2.b7 Ne4

3.g8N+! ...

The first underpromotion. The only move to avoid the threatened mate.

3.g8Q?? Nd6 mate;

3...Ke8!

Black must stop the enemy King from escaping.

3...Ke6 4.Kd8 Bxb7 5.a8Q Bxa8 6.c8Q Nec5 7.Qxa8 Kd6 8.Qa7 Kc6 9.Ne7+ Kb5 10.Qa2+-;

4.Nf6+! ...

Again White has no choice in moves.

4.a8Q Nd6 mate.

4... Nexf6

5.a8B!! ...

The second underpromotion. White has to find a defence against the threatened mate ->Nd5 -> Ne7. His only defence is to set up stalemate so he is forced to promote to the only piece that cannot move !!

5.a8Q?? Nd5 6.Qxa6 Ne7 mate;

5...Ne5!

5...Nb6+ 6.Kb8 Kd7 7.c8Q+ Nxc8 8.bxc8Q+ Bxc8 9.Bb7=;

6.Kb8 Nc6+!

6...Nfd7+? 7.Ka7+- ;

7.Kc8 Bf1

Black threatens mate with the Bishop. White is required to make another promotion but with which piece?

8.b8R!! ...

The third underpromotion.

8.b8Q Ba6+ 9.Qb7 (if 9.Bb7 Ne7#) 9...Ne4 10.Qxa6 Nd6 mate;

8... Ba6+

9.Rb7 ...

9.Bb7?? Ne7 mate;

9... Ne7+

Black lifts the stalemate threat but there are no winning chances.

10. Kb8 Nc6+

Black takes the perpetual. It is a DRAW. A very memorable study showing great skill in composing with the three different underpromotions.

PRACTICAL CHESS ENDINGS CD

ChessDevon, in collaboration with PCE has produced a CD that includes practically all the endgame positions that have appeared  on this site. This CD contains 363 endgame positions taken from games and studies.  Nearly all the positions are preceded by a pen portrait of the player or composer.  A built-in programme is provided on the CD to play through the endings.

"PRACTICAL CHESS ENDINGS" is available at £12:50 (including UK postage) from "ChessDevon".

I would like to briefly summarise the type of endings found on the site. These are; (a) Basic endings. (b) Practical chess endings. (c) The Endgame study.

All these are interrelated and important and you cannot understand (b) or (c) without a knowledge of (a).

(a) Basic Endings. These are theoretical positions in which we know the correct result with optimum play by both sides. They may consist of three pawns or less and also include all the non-pawn and five piece endings which have now been extensively analysed by computer and of which we have tablebases. In the days when we had adjournments some of these endings could be looked up in text books to give us some idea how to play the position. As we no longer can do this, knowledge and memory of these endings has become important in practical play. Fundamental Chess Endings (2001) by Muller and Lamprecht and Basic Endings (1992) by Balashov and Prandstetter and the earlier A Pocket Guide to Chess Endgames (1970) by David Hooper are good introductions to these endings.

(b) Practical Endings. These occur in over-the-board play where usually more pawns are present. The above ending is an example of this type. Some of these endings are in the process of being transformed to basic endings but often they finish before this stage is reached. Endgame strategy is very different from the middlegame and has its own set of rules and exceptions. Fine's book Basic Chess Endings (1941,2003) recently revised by Pal Benko and Batsford Chess Endings (1993) by Speelman, Tisdall and Wade are about basic and practical endings and both can be recommended.

(c) Endgame Studies. These are positions which have been composed and will contain elements of one or both of the above types of endings. But there are important differences between these types and the study, such as artistic form and economy of construction. An endgame study has to follow strict rules of composition, especially if it is entered into a composing competition. One of these rules states there should only be one solution. If there is an unintended second solution then the study is unsound and said to be "cooked".

Endgame studies are important to the practical player because they enhance his imagination and help him learn and enjoy areas of theory without too much effort.

John Nunn's Endgame Challenge (2002) is an excellent introduction to using endgame studies as a training tool. Walter Korn's American Chess Art (1995) is a basic introduction to the endgame study and a more comprehensive work is John Roycroft's Test Tube Chess (1972).
