I've found a link ( http://www.geocities.com/TimesSquare/6298/ajedre8a.htm ) to an other position where a fortress is involved and program are challenged to find the right solution: The position is the following : [D]8/6p1/7k/7B/6PK/2p2P2/8/8/ w "In this position, we have a fine example of the Never Concept. Black's passed pawn is about to promote, and cannot be stopped. A black queen will appear on the board. However, white can draw by creating a fortress to enclose the enemy king." And the solution is White to play and draw: 1. g5+ Kh7; 2. Bf7 c2; 3. Kh5 c1=Q; 4. g6+ Kh8; 5. Kg4 How many nowadays comps are able to see the draw ? w.b.r. Otello
