|Feb-13-06|| ||Autoreparaturwerkbau: <Blitz 5> was surely a very strong computer. It probably had 64B of hard disc, over 70 mix-coloured bulbs, half-a-mile of wires, a prototype of RAM and other terrific hardware. And of course, it took 2 floors of building.|
|Apr-27-06|| ||dakgootje: If you look at the strenght of most of the chessplaying computers back then its a very nice combination by black!|
|Apr-27-06|| ||dutchboy13: black was a really good computer i like the way this was played|
|Apr-27-06|| ||THE pawn: Black to play and win
It would be a good monday puzzle.
|Apr-27-06|| ||dakgootje: <THE pawn> Maybe more of a tuesday as there is some, not much but some, calculation needed.|
|Apr-27-06|| ||THE pawn: It would be a bad monday puzzle.|
|Jun-13-07|| ||piroflip: it was around this time that a clubmate of mine stated that "computers will never play to grandmaster standard". this combination is G/M like in my book.|
|Dec-12-07|| ||OhioChessFan: Whew. I spent 10 minutes looking at various Engine's game pages and gave up. Looked back at the clues page and it was solved! How exactly did you find this Aurora?|
|Dec-12-07|| ||Aurora: Yabba Dabba Doo !!!!!!!!|
|Dec-12-07|| ||Aurora: <OhioChessFan> I spent 3 minutes clicking through|
Number of moves is: no more than 20 moves
Result is: black wins
|Dec-12-07|| ||OhioChessFan: LOL, I just randomly worked through the older computers. How'd you figure it was Black winning?|
|Dec-12-07|| ||Aurora: <OhioChessFan> I checked out white wins first. Negative.|
|Dec-12-07|| ||al wazir: What happens after 11. Nxe4 ? If 11...Qh5, then 12. Ng3. If 11...Qxe4, then 12. Kxh2.|
|Dec-12-07|| ||The beginner: <Al wazir>
After 11 Nxe4
12 Ng3 .. Qxg3!
Threatening mate Qxg2 or if white takes the Queen
13 fxg3 then Nf3 mate.
|Dec-13-07|| ||al wazir: <The beginner>: Thanks. I should have seen that; it's essentially the same as the combination that yielded mate in the game as played.|
|Dec-13-07|| ||arnaud1959: <piroflip:..."computers will never play to grandmaster standard"> In early 80's people were about to give up on working on chessprograms because they understood that a computer should calculate too much moves to be able to beat a human with a deep positional understanding. Since then à lot of progress has been made in calculating capacity of computers and in strategy simulation.|
|Feb-16-09|| ||m0nkee1: that is a very nice attack :) well done puter|

11.Nxe4 Qh4 12.Ng3 Qxg3 13.fxg3+ Nf3#, would have been quite unusual and very pretty indeed - to let the opponent capture your queen with check and then block this check with your own double check / mate, with the knight arriving just in time to defend the attacked rook - it doesn't get much prettier than that.

Granted it is not terribly difficult to see.
|Apr-19-17|| ||RolandoFurioso: Very impressive indeed - back in 1978! 10...Rxh2!! is definitely a stunning move that immediately wins.|
I've just checked the position after 10. O-O with some recent chess engines: while requiring less than 20 minutes search time, they even announce mate here - e. g.: 10. .. Qe7-h4 (+M11/17 1125
Fischerle_0_9_80_SE_64Bit) h2-h3 Ne4-g5 Bc4-e6 d7xe6 Qd1-g4 Nd4-f3+ g2xf3 Ng5xh3+ Kg1-g2 Nh3-f4+ Qg4xf4+ Qh4xf4 Rf1-h1 Rh8xh1 Kg2xh1 Qf4xf3+ Kh1-g1 Qf3xf2+ Kg1-h1 Qf2-g1# (M11)
And there seems to be an even fasterv line to mate (M10) that starts with 10. .. d7-d5: 10. .. d5 +M10/51 3635 Stockfish 7 x64 11. Nxe4 Qh4 12. h3
Bxh3 13. Nxc5 Bxg2 14. Nd7+ Kf7 15. f3 Qg3 16. Bxd5+ Ne6 17. Ne5+ Kf6 18.
Ng4+ Ke7 19. Bxb7 Rh1#)
