I had Colossus Chess X from Martin Bryant in it for AtariST but this successor of colossus 4
lost all games !!!
i then thought, ok my version for atari ST is maybe broken. So i tested it by trying to replay the
games with the PC version of Colossus Chess X.
and as a surprise, the PC version reproduces almost any move the AtariST version did.
So i would say that there is a huge bug in all Colossus Chess X versions that reduced playing strength.

In comparison i therefore put the version 4 in, i had good experiences in my youth.
And instead of 1 mhz for the C64 i put in on 4 mhz.
this version plays very good against the 68000 CPU opponents.

(How can I present the tournament table in a better formatted way ?!)

The games I play here are 40/120 20/60.
To get a picture how Colossus chess X Played, it lost all 8 games!!!
While Colossus chess 4 on the C64 has 5.5 out of 8 so far.

That seems to indicate a really huge bug in the program, but it was sold in this way commercially with this bug for 68000 and PC.

I put the 100 MHz Nigel short into the tournament too to get the first reliable results. Also David broughtons PC engine sold by Parker at that time called Philidor.

I played white against the analysis board from move 58.

Fixed it for you!  

Yes of course this is all stronger then these old machines on fossile hardware.
Nevertheless the tournament has brought one new insight sinnfällig: colossus chess X on Atari ST/Amiga or PC is broken.
Colossus chess 4 for z80 or C64 is stronger !!

And we can proof this.

Manual tournaments as in the old days. Tuning / testing your engine in the 80's was a royal pain. For years I played 1 or 2 tournament games (40/2hr) a day, watching the screen, making notes. No PGN, no EPD, you had to write down the position on paper and later type into the engine to judge if a program change was needed.

Regarding the Nigel Short, it was in the middle of the looming bankruptcy of Hegener & Glaser when mister Hegener begged me for a new 6502 version because he had an opportunity to enter the UK market. I had none, I had moved to the ARM RISC processor, later known as the ChessMachine. I wasn't in the mood but decided to do it anyway, this man has been so good to me. And so I took a few goodies from the ChessMachine and the Nigel Short was born. Very few were sold, but that I expected on beforehand, the UK is a small market.

BTW Thorsten, what are the hardware specifics of the Mach IV?

Yes. The results of the mach IV look very strange.
It should be 68020 but would this explain the magnificent results ?

I will unscrew the body and look what it is. Not that it is faster then we think...

The nigel short plays more active then the mephisto milano brother.
But recognize this machine runs on 100 mhz. So the game of colossus chess c64 with 4 mhz is not that bad. Colossus could have won if it would have played c6 pushing the pawn in the right moment, but failed and therefore the game went only a draw.

Yes. The results of the mach IV look very strange.
It should be 68020 but would this explain the magnificent results ?

Indeed. But it had position learning on board. It could explain.

Regarding the Nigel Short, it was in the middle of the looming bankruptcy of Hegener & Glaser when mister Hegener begged me for a new 6502 version because he had an opportunity to enter the UK market. I had none, I had moved to the ARM RISC processor, later known as the ChessMachine. I wasn't in the mood but decided to do it anyway, this man has been so good to me. And so I took a few goodies from the ChessMachine and the Nigel Short was born. Very few were sold, but that I expected on beforehand, the UK is a small market.

Nigel Short is one of our best players, and the only I can personally remember getting to the world championship final (if I'm honest, I don't know of anyone who thought he might beat Kasparov in that match). I've also got one of his books (an easy one for weak players). But frankly, you're not likely to see many people busting a gut to get an expensive chess computer just because it's got his name on (I have two chess computers with Kasparov's name on them). We never loved Nigel Short like we loved David Beckham or the Spice Girls - even those of us who knew who he is!

It had to do with the bet:

I like the shiny chrome white pieces - would look good on any coffee table. 8k RAM sounds Jurassic today!

the tournament has made progress:

Some highlights:

the unbeatable Mach IV gets beaten by Mephisto Montreal (that has the ROMA 16 Bit in it).
