Below, you see an improved version of it, as the author
It might be that this would have enhanced the score with The first Applet shows the deceptive solution. Black plays after 8-3 (20-25) 7-2 (29-33) 19-14 no (33-39), as white wins through 3-17 (39-43) 17 x30!!Therefore, black will play another move. All subsequent moves are forcings for black, until the surprising end with (49-32!!) 45 x 34 (32-23). White cannot play now 24-29 and it ends in a draw. It must be done otherwise, by an offer, resulting in only three pieces for white. An important aspect of this end game is the fact that after 19-14, 8-3 (29-33), white can only win by a stroke to 48! On the stroke 3x43 follows (4-9!) 7-1 (32, 38) with a draw. Later on it will appear what is so remarkable about this. Black is able to defend himself in this variant by another way, i.e. by playing (15-20) after white's 7-2 instead of (33-39). This leads to a beautiful ending that can also be accomplished by the way given in the Applet below with black to move. This end position has many sharp (harakiri) courses. It's time for the main variant. Black can make it more difficult for white by playing (15-20) instead of (28-32), after white's stroke 3x48. The next trial of white for win seems logical, but black has again a surprise, as shown in the fourth Applet! All this leads to the most remarkable aspect of this end game. White was not allowed to go to 43 after. (29-33). But now, after black's move (15-20) is 48-43!! the only winning action. So, the main variant is: 2. Jaap Bus
In this position it is clear that 12-8 doesn't win after (29-34)
After the offer 30-24 and
12-8 (22-27) 8-3, black has a choice
The key move after (20-24) is 3-26! With the course as given It will appear that after (20-25) the solution is quite different. The position after 8-3 is given in the next Applet, with a choice for black between (20-24) or
(20-25). Now it is apparent that after
(20-25) white cannot win: 3-26 (36) 26-42 (27-32) 39-34 (23-28) =. Nevertheless, white is able to win on a spectacular way. The climax is the move 47-42!!

One would not expect that this could happen from the initial position.
The first Applet gives the sharp variant if black gets one king. The main variant comes next, below. The second Applet
(black to move) shows one of both possibilities for black to get two kings. |
