By the way, TobyChess should solve this easily (if I read their promotion stuff correctly)
But could it compose anything near as clever as this?
NO!
Why?
Because computers are stupid.
I've not read all that promotional gunk does it tell you what TOBY stands for.
T.O.B.Y. or is it just a name plucked from the air?

Toby is his son's name if I understand correctly. I would check it on their website but the bunch of sad chess geeks have pulled it down

Knights do not frolick, they leap.
Now close your dictionary or what ever it is you are using.
You have have had your moment in the sun with' ploughboy chess'.
Frolicking Knights indeed....that's Double Dutch to me. 😉
Computers Bah!

"In 4-6 years, there ill be no more chess engines as chess will be
solved and the
moves will simply be looked up in tables (similar to the dinosaur
methods of tablebases used today). "
this one bit reveals it's some kind of a scam I believe. That is some freaky exaggeration. 10 years would be just ignorant, but 4-6 years means you're full of it. In 4-6 years, I expect the 8 men tablebases to be completed at the most, which is itself probably an exaggeration. This guy either has some deadly innovations stored up in his closet that will revolutionize not only the chess world, but also the tech world, or he doesn't have a clue.
"World's Strongest Chess Program that can beat Rybka 3.1"
oh and just noticed this, there's no such thing as "Rybka 3.1".

I just looked at the pgn file posted on his web site. Assuming no cherry-picking is going on, Toby PC slightly edged out Rybka 3 (1-cpu), but then again, the Robbos etc seem to be doing that also.
Myself, I'm happy just using the free Stockfish 1.6 ja, which isn't too far below the Rybka 3 performance level. And it's even stronger than the free Rybka!

2. It solves about 1/2 of the Nolot puzzles on Wikipedia. hese are
puzzles too hard for chess engines to solve. On puzzle 9 we found a
novel solution (Nxh6) which wins in every variation! Neither Robo or
Ryka can solve more than 1-2 of the 20 puzzles. We find unique moves
in many situations because of a special King attack routine we
invented. I have seen ...[text shortened]... run the positions in Fritz 12 it also finds the same moves, therefore
Fritz 12 must be a clone too?

Hi Heinz - did use ploughboy chess after all.

I see you run a pub team in the Birminham Chess League.

Originally posted by Fat LadyI guess he's using this Nolot testing as one reason why Toby Tal isn't a clone of Robbo. I have no opinion on that issue, but I did have fun playing around with the Nolot test suite.

etc because we play the same moves in a position that they do...
From what I've read, it's 11 positions, not 20. Toby didn't say how long he let engines run on each position, so I arbitrarily tried 60 seconds per position. My results for a few engines:
The free Rybka 2.2n2 x64 - 2/11 positions solved.
RobboLito 085e4 x64 - 2/11
IvanHoe v73 x64 (in the same family of Robbo) - 6/11
Stockfish 1.6 x64 ja - 5/11
Stockfish 1.6s x64 sj settings - 7/11
See this link for the sj settings for Stockfish 1.6s x64:
http://talkchess.com/forum/viewtopic.php?t=31887
I'll note that some of these engines also liked Nxh6 for problem 9. The answer for Problem 9 is supposed to be Ng5, but apparently the experts aren't certain that this is correct. (Pretty much no engines can solve this one.)
I think that the Nolot test suite is designed to showcase a certain sacrificial ability; I'm not sure how correlated it is to engine strength. For example, RobboLito 085e4 seems to be rated higher than Stockfish 1.6, yet it performs worse than Stockfish on the Nolot test.
