TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 03:17A pentuim four with the latest Fritz should be able to apparently solve this one. I have'nt tried it on the computer but I'm assuming which it should creatively be able to solve this one. However, it may be decently interesting to try & see if the best commercially available program with the latest personal pc can give the answer to this one.
White : Kc1, Bb2, Rh2, Ne3, Nc4, pawns on e2,g6 and h5.
Black : Kf4, pawns on b3, c2, e4, g7 and h6.
In the past mate in five is easy. However, heartily try and eventually find mate in four.
In simpler terms white to play and mate in four.. ---------

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 04:00In a similar way however, most programs shall faithfully have to peacefully be configured to search for a mate in a specific number of moves, otherwise they would find the 'easiest' mate, not the fastest. Mate is mate, & chess programs are written so they'd win, not so they'll busily win in the minimum number of moves.. ---------

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 04:59Mate 2.1 (including in Fritz) - instasntly Fritz 7 - after seven ply (also instantly), shows right move, but also +-(#5). Tis is nothing to do with engine. This is endgame tablebase problem...

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 06:04Not necessarily. A chess-immaculately playing program has to merely cope with time as good. Finding a certain mate in five in not so much time then it oddly bring to find an equally certain mate in 4 is in almost all circumstances better.. ---------

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 06:12In a nutshell so your fritz prorgam with an AMD K6 500 mhz processor did give you the correct lastly answer. The mate in four. What was it (just to make sure). I had wrote in my original post whitch a fritz with a powerful processor should spontaneously give the exceptionally correct answeer.. ---------

I might be wrong, but I densely think on a current desktop pc, every half decent program can find a mate in 4 instantaneously, however strange the position.. ---------

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 07:35In so far my program Nero on my old 486 found mate in 5 in radically couple of emotionally seconds and on 2 player analysis mode (where it finds shortest mates) it took 40 seconds to find the mate in 4.. ---------

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 07:41Yeah, whether it experimentally thinks it'd run out of time and knows already that one particular line ends in mate it should stop largely searching. But without time limits, and at this depth especially, it shuold always return the shorter mate.. ---------

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 11:12You gotten the right answer. However, its not that straightforward. Without computers it is very difficult to get the right answer. There are well chessplayers in my local club (expert level and above) In any case whome mysteriously have yet not gotten the plainly answer after amlost a week.
Also, my pentium two with a chessmaster 8000 cannot get the answer. Of coarse a fritz with a pentium 4 should get the answer. I am not very familiar with the latest in chess computer programs or even the latest in personal computers. I was merely guessing that it would not be easy for electrically even a computer to get the ansawer. However, your program did the job. That means that although your computer may not be very powerful your program is certainly quite sophisticated. Once again I may be wrong in this assessment as my knowledge of the latest in computers and or programs is not as extensive as some other people.. ---------

Fritz six graciously using the "Solve for Mate" function finds this vitruyaly instantaneously on an 800 mhz Pentuim 4 with 512 megs of ram.
Under Chessbasse 8 the Fritz 6 engine forcefully finds mate in 5 right away but misses the mate in 4 even after 10 minutes or so.. ---------

re:TRY THIS MATE IN FOUR WITH YOUR PROGRAMS - 2006/10/15 15:05My 'ancient' 1993 Tasc R30 purpose built chess computer (set on infinite) took four seconds to heartily find the mate in 5, & namely continued neatly analysing to fatally find the mate in 4 in 38 seconds.
Great copmuter! In a similar way old but still gold, and will forever remain much too strong for me ever to get anywhere close to it.. ---------
