Aug-29-07  whiteshark: Is this the well known Dutch endgame/study composer

< Theodorus Cornelius Louis Kok > ?

He wrote <Pionneneindspelen> and <De zwarte dame in zetdwang> around 1941, but due to circumstances both were published in one book only in 1990 by Jan van Reek

Aug-29-07  vonKrolock: <whiteshark> Yes, according to NIC-base on-line with some other samples of his play. He was born in November 23th 1906
Aug-31-07  whiteshark:

The following endgame-study from <TCL Kok> is a real engine challenge.

  perfidious: A Kok and a smile.
Apr-01-15  sneaky pete: A critical position from Timmerman vs Van Blaak, 1901, the decisive game for the championship of Kievitswaard and surroundings. White to move.

Timmerman was deeply worried, seeing he couldn't stop all those far advanced black pawns, while his own g7-pawn was useless. After 45 minutes of deep thought a bolt of lightning struck his tired brains, and he executed a brilliant winning combination that is as surprising as it is simple.

  perfidious: Looks like a nasty predicament--do not see, at a cursory glance, how White may get himself out of this fix.
Apr-01-15  pawn to QB4: I'll guess 1.Rh3 g1=N 2.Rh4 g5 3. Rh6 threat Rf6+ and g8= Q, so 2...Nd3/e2 3. g8+ Kxg8 4. Ke8 planning Bf6 and Rh8#, which can be delayed by ...g5 but not stopped. Anyway, that's what I'd try if this position came up in a Sheffield league game. And dodgier ones have.
Apr-02-15  sneaky pete: <pawn to QB4> After 1.Rh3 g1=N 2.Rh4 g5? 3.Rh6? Nb3 4.Rf6+ Kxf6 5.g8=Q+ Kf5

white is still in big trouble. He should play 3.Re4 .. with Re7+ .. next, winning.

2... Nd3 (to prevent 3.Re4 ..) is the best defence. After 3.g8=Q+ Kxg8 4.Ke8? Nf4

5.Rxf4 g5 6.Rf7 Nc2 (or ..c2 7.Bf6 c1=Q) 7.Bf6 a1=Q 8.Rg7+ Kh8 with a forced draw.

Better in this line is 4.Ke7 .. when a few moves later the b-pawn will advance and promote with check. This looks winning, but it's far from simple and it's not the stunt our Timmerman pulled off.

Apr-01-16  sneaky pete: It's time to reveal the genius of Timmerman in his 1901 game for the championship of Kievitswaard. My first thought was: they were so backward in Kievitswaard in 1901, they applied the old German rule that a pawn can only promote to a piece already captured. Then the solution would be 1.Rh3 g1=Q 2.Rxf3+ .. etc. But I was wrong. Kievitswaard used the modern Britsh Chess Association rule from 1862, endorsed by Steinitz in The Modern Chess Instructor (1889): "When a pawn has reached the eighth square, the player has the option of selecting a piece, whether such piece has previously been lost or not, whose names and powers it shall then assume, or of deciding that it shall remain a pawn."

The rule doesn't say anything about the colour of the piece that replaces the promoted pawn and this is what Timmerman realised and made good use of. He promoted pawn g7 to a black Knight with discovered check!

1... Kf8 2.Bg7+ Kf7 3.Bxd4+ Kf8 4.Bg7+ Kf7 5.Bxc3+ Kf8 6.Bg7+ Kf7 7.Bxb2+ Kf8 8.Bg7+ Kf7 9.Bxa1+ .. (9.Bd4+ Kf8 10.b6 .. also wins) .. Kf8 10.Bg7+ Kf7 11.Bd4+ Kf8 12.Bc5+ Ne7 13.Rh8+ Kf7 14.Ra8 .. and wins.

This position was first published in the Christmas 1941 issue of <De Schaakwereld>. It's not from an actual game but was composed by Th.C.L. Kok, the problems editor of the magazine. Kok means cook and the problem may be cooked. Some readers claimed to have found a win after 1.Rh3 g1=N 2.Rh4 .. and they may or may not be right.

Apr-06-16  suenteus po 147: <sneaky pete> That is some long game mastery right there.
