Please, elaborate. What was the engine that could? I think I can; I think I can. And which engines could not solve this problem or others?

About a month ago I was doing a post-game analysis with Crafty. When it got to the position where I executed a winning combination I was surprised that Crafty could not find the winning move. Crafty kept insisting on a move that drew instead.
Later, I saw in one of Alexandra Kostiniuk's podcasts in Chess Killer Tips where a simple mate in 2 was prese ...[text shortened]... Mate in 2 by Almira Skripchenko

16 May '08 13:29Originally posted by heinzkatright, someone should try to place them in an engine as I bet an engine would find very difficult to solve them....
1. Rxb3 cxb3 2. g6 Qxg8 3. Kc5 d6+ 4. Kd4 d5 5. Kc5 d4 6. Kxd4 1-0, right? Second one is a fortress position via K=>f2, indeed well-known (solution is also given on the linked web page...)
