Djaja study, Big deal! Bright finds the line faster than Rybka and Deep Fritz
[d]6R1/P2k4/r7/5N1P/r7/p7/7K/8 w - - 0 0
"In his book "The King" GM Jan Hein Donner writes: "White makes one more move and it’s a draw! Keres, the two Byrnes, Lothar Schmid, Bisguier and I sat staring at this position for more than half an hour. We couldn’t find it. Can you?"
Hans was convinced that computers would also fail miserably. So Frederic Friedel bet him a glas of whisky at the bar that Rybka would find the key move. "Not necessarily understand why it holds the draw," Friedel said, "but it will find the move by discovering that all other moves lose badly and quickly." Hans lost his bet, Rybka found the right strategy in one minute and two seconds."

On my slow Quad 2Ghz Q9000 Laptop it took just 10 seconds.

i'm sure at least 3 people here know of insoluble (by current engines) puzzles!Send us an insoluble study!
That's that. Are there any studies that these monsters cannot solve? Anyone who sends us a nice puzzle – something as elegant as the position above – which chess engines cannot figure out, can win a Deep Fritz 11 signed by all the players of the Dortmund tournament. Maximum three. Please use the feedback button on the left side of this page and give "Computer puzzle" as the subject line (anything else may cause your letter to be ignored). And please give us the position and solution in PGN.

Re: Djaja study, Big deal! Bright finds the line faster than
Yep,
even on my slow AMD X2 2.6GHz Bright took only 15 seconds.
This position is well known from Eigenmann's endgame test as E_E_T 089.
6R1/P2k1N2/r7/7P/r7/p7/7K/8 w - - bm Nh6; id "E_E_T 089 - T&S vs T&T";
kind regards
