A selection of Dutch endgame studies

By Harold van der Heijden

Jan Marwitz

1st prize Tijdschrift van de KNSB 1937WIN

The win must come from the e5-pawn. But the obvious 1.e6? fails to 1…Se2+ 2.Kf1 g2+! 3.Bxg2 (Kxg2 Sf4+;) 3…Sg3+ 4.Kf2 Sf5 (Sh5). Only the spectacular 1.Bd3! wins: 1…Kb7 (Sxd3; e6) 2.Bc4 Kb6 3.Kg2 Kc5 4.Kxg3! Kxc4 5.e6 Se2+ and now almost every K-move fails. Of course 6.Kg2?, 6.Kf3? and 6.Kh3? fail to a direct fork, while 6.Kh4? Sd4 (Sf4) 7.e7 the bS also forks. Only 6.Kh2! wins.

Beautiful miniature with multiple sacrifices from Jan H. Marwitz (1915-1991), the best Dutch endgame study composer of all times.



J. Selman

1st prize Tijdschrift van de KNSB 1949WIN

1.Sf5! clears the a1-h8 diagonal and threatens 2.f7+. 1…Re1+ Now White is unable to protect his bishop as 2.Kb2 closes the long diagonal again. But: 2.Kd2 Rxa1 3.f7 and now after 3…Ra2+ White must be very careful. E.g. 4.Kd3? Bxf5+ and 5…Kg7. 4.Kc1? Ra1+ 4.Kb2 Rb1+ 6.Kxb1 Bf5+; 4.Ke3? Ra3+ 5.Ke2 (5.Kd4 Rd3+! or 5.Kf2 Rf3+!) 5…Ba6+ 6.Ke1 Re3+ 7.Sxe3 Kg7 draws; 4.Kc3? Rc2+ 5.Kb4 Rb2+! 6.Ka3 Ra2+ 7.Kxa2 Be6+ draws. Only 4.Ke1! works. 4…Ra1+ 5.Kf2! g3+ Now 6.Kxg3? fails to 6…Rg1+ 7.Kf2 Rg8, so 6.Ke3! Ra3+ 7.Kf4 (Kd4? Rd3+!) 7…Ra4+ 8.Kg5 Rg4+ 9.Kh6! Rg8 (9…Rg6+ 10.Kxg6 Bxf5+ 11.Kf(h)6) 10.Se7 Be6 11.fxg8Q(R)+ Bxg8 12.Sg6 mate.

John Selman (1904-1978) was famous for his in-depth investigations and e.g. unravelled the story of the Saavedra-study. Perhaps his above study is one of the best Dutch endgame studies ever. It anticipated a famous 1951-study by GM Vladimir Korolkov (HHdbIV#24982). Of course it is understandable that Korolkov didn’t know about Selman’s study, but for some reason the Russians for a long time argued about the relevance of Selman’s masterpiece. But in his posthumous book “I choose the idea” (1998) Korolkov simply writes “as is turned out, this study has a predecessor”, quoting Selman’s study.

J. van Reek

Commendation Shakhmaty v SSSR 1969 WIN

Harrie Grondijs pointed out that the initial position of this study pictures the double DNA helix. 1.dxe3 fxe6 2.exd4 exf5 3.dxe5 fxe4 4.exd6 exf3 5.dxe7 fxe2 6.e8Q wins.

Jan van Reek (1945) is by far the most prolific Dutch writer on endgame studies. He also invented a new genre: “ultra-modern endgame studies”, i.e. studies with several phases.



H. Weenink

6th prize Kagan’s Neueste Schachnachrichten 1920 WIN

With a piece up this at first sight looks like an easy win. But it is not easy at all! For instance 1.Bb3? fails to 1…Kc3 2.Kb5 (2.g6 Kd4 3.Kb4 Ke5) 2…Kd4! 3.Kc6 Ke5 4.g6 Kf6 5.Bf7 Ke7 and the bK reaches f8 and draws. Also seizing the opposition by 1.Kb4? fails to 1… Kxc2 2.Kc4 Kd2 3.Kd4 Ke2 4.Ke4 Kf2 5.Kf4 Kg2 6.Kg4 g6 and Black got the opposition after all. Not so easy to refute is 1.Bd1? since 1…Kc1 (which the composer intended) fails to 2.Bh5 (Bb3) Kd2 3.Bf7! Ke3 4.g6 Kd4 5.Kb5 Ke5 6.Kc6 Kf6 7.Kd7. But, luckily, 1…Kc3 2.Kb5 Kd4 3.Kc6 Ke5 4.Bc2 and now not the composer’s 4…Kf4 5.g6 Ke5 6.Kd7 Kf6 7.Ke8 wins, but 4…g6! 5.Bxg6 Kf4 draws.

The amazing key move is 1.Bb1! Kxb1 (1…Kc3 2.Kb5 Kd4 3.Kc6 Ke5 4.Kd7 g6 5.Ke7 Kf4 6.Kf6 wins) 2.Kb3 Kc1 3.Kc3 Kd1 4.Kd3 Ke1 5.Ke3 Kf1 6.Kf3 and wins, e.g. 6…Kg1 7.Kg3 g6 8.Kf4.

Henri Weenink (1892-1931) was a very talented Dutch problemist who died at an early age. Perhaps his Bb1-study features the most surprising key move of all Dutch endgame studies.

Jan Timman

The Art of the Endgame 2011WIN

Composed 2010, dedicated to Harry Mulisch

White will lose a piece: 1.Rd7+ Ke6 2.Rxc7 since Black has 2…Re3+. If now 3.K- Black can play 3…Kxe5 and the bK is able to defend its rook after 4.Re7+. However: 3.Sf3! Rxf3+ 4.Kg2, threatening both to capture the bR and to check on c6. 4…Rc3! 5.bxc3 After 5.Rc6+ Ke5! 6.Rxa6 Rc2+ 7.Kf3 Kd4! Black wins the rook ending. 5…Bb5! A spectacular move blocking the b-file. Now it seems impossible for White to prevent promotion of the b-pawn. However: 6.Rc5 and the bB is in problems (6…Be8(Ba4) 7.Rc8 and White even wins), 6…Bd7 and now only the illogical looking move 7.Rg5! stops the b-pawn. 7.Rh5? Bc6+ 8.K- b2 as h1 is covered. If now 7…Bc6+ e.g. 8.Kf2 b2 9.Rg1. 7…b2 8.Rg6+ and 9.Rb6 even wins.

GM Jan Timman has always had a passion for endgame studies. His most recent book, from which I quote the excellent study, is his first book fully dealing with endgame studies. Highly appreciated!


The study above was dedicated to Harry Mulisch (1927-2010), who is considered to be one of the best Dutch post-war writers (and regularly thought of as a possible Nobel laureate). In 2007 his 1992 novel The Discovery of Heaven was elected as the best Dutch novel of all times.

Harold van der Heijden

Algemeen Dagblad 18i2003 WIN

This position I discovered while I was working on an article on pawn breakthroughs in my magazine EBUR. It appeals to both beginners as well as very strong players as it can be solved by everybody by the trial-and-error method, while it is still fun (i.e. difficult) for the more gifted o.t.b. players. Surely, everybody appreciates that White’s win should come from a pawn breakthrough combination. However, 1.g5? fxg5 and Black even wins as the black g-pawn advances with check. And 1.e5? fxe5 2.g5 e4 3.g6 e3 4.g7 e2 5.g8Q e1Q is a draw. Perhaps 1.Kh3? In that case, after 1…Kf3! White has nothing better than 2.e5 fxe5 3.g5 e4 4.g6 e3 5.g7 e2 6.g8Q e1Q with a draw we recognize from the 1.e5? line. The only legal move that remains is the surprising 1.Kh1!, which is “of course” the solution. Obviously, if Black plays to the e-file (1…Ke3) then White plays 2.e5 fxe5 3.g5 e4 4.g6 and the black king obstructs his e-pawn, while playing to the g-file (1…Kg3) allows White to promote with check: 2.e5 fxe5 3.g5 e4 4.g6 e3 5.g7 e2 6.g8Q+ and win. More difficult is 1…Kf3. White then plays 2.e5! (not 2.g5? fxg5 3.e5? – still attempting to win – 3…Kf2 and White is mated) 2…fxe5 3.g5 e4 and now 4.Kg1! e3 5.Kf1 and wins. But, almost everybody asked, what about? 1…Kf1, that seems to change nothing to the initial position. But it does: 2.e5! fxe5 3.g5 e4 4.g6 e3 5.g7 e2 6.g8Q e1Q with a position that we have seen with the kings shifted one or two files up. Here’s the difference: 7.Qg2 mate!
