I am interested to see the positions when only doctor can find the right move. I started to test doctor3 in hard combinations for programs when usually programs cannot find the right move at tournament time control(they may need an hour or some hours) and I did not find that doctor3 is better in solving these positions. Here is one example: [D] 3r1b1k/pp6/2n2q1p/2Bp1B1Q/5P2/1P4p1/P7/4R1K1 w - - 0 1 Doctor3 could not find Re6 after more than 1 hour of search on pentiumIII450 Uri
