Shogi Game 20 (amateur, some comment).

Below you find the first contribution of Reijer Grimbergen. He is one of
Europe's top players and won already several major European tournaments.
On 25 juni 1990 at the house of RICOH Europe in the Netherlands a game
was played between Reijer and Tanigawa Toshiaki. Maybe the last name
rings a bell. But if it does, you are only partly right. Tanigawa Toshiaki
is the brother of the professional player and former Meijin Tanigawa Koji.
The ability to play Shogi runs in the family, however, because the amateur
Tanigawa has the highest amateur grade (6-dan) that can be obtained.
You might wonder what Tanigawa Toshiaki does in Holland. Well, he works for
RICOH and recently started working at their European department. His
presence can do Dutch Shogi a lot of good and I hope it will prove to be a
stimulus for the whole of European Shogi.

Both sides had equal chances, even in the end game. Reijer throws away his
chances on move 37. 37.Kx6h instead of 37.Gx6h effectively brings whites
attack to a standstill, e.g. 37. ... G'5f  38.+Px3b Kx3b  39.Bx1a+ and 
although black probably does not have an immediate mate, Tanigawa did not
see any clear way to continue his attack.
After 42. ... +Rx6i, black cannot defend anymore, so he must go for an all
encompassing attack. Since only mating the king is important one can invest
as many pieces as one has. This time, however, it was to no avail.
