He contacted the KNSB ( Dutch Chess Federation)who provided book and money prizes. My good old friend Hans Bohm provided 15 beautiful statues. I wish to express my gratitude to them. I contacted Harold van der Heijden with the question if he wanted to become the tournament director( again!) and he consented. Early October he sent me 91 studies,as usual in anonymous form.Van der Heijden had checked all studies on soundness and anticipations. He confided to me that he had spent a quarter of an hour on each study. A tremendous amount of work and I thank him for his efforts. The 91 studies were a rich harvest; there were theoretical investigations- even on the 9th game of the first Karpov-Kasparov match-that were certainly worthwhile. I concentrated, however, on complicated and beautiful twists and combinations in endgames.My first selection contained 37 studies, a clear sign that the general level was high.In my final selection quite a few good studies were left out; they may score well in other tourney's. I take this opportunity to thank all composers for their entries. Before I made my final decision I asked GM Erwin L 'Ami for advice, as I did 10 years ago for my 60JT. Our views didn't differ that much,but he helped me to make some important decisions,eg about the first prize.While I could guess the names of the 2nd and 3th prize with almost certainty, the overall winner came as a surprise.There is a seperate section for studies by strong players, a proposal of Harold.In fact a special prize was awarded in this section by Jan Sprenger. While Alexander and Victor Mikhalevsky were dominant here, special attention should be given to 15 year old Dommaraju Gukesh who sent in a well thought out study.I hope he will continue on this path and become both a great player and composer.} 1. f8=Q $1 Ra4+ $1 (1...
