the Mchess project continues.....

[Bill Rogers]

I bought a copy of MChessPro years ago. It cose me $500.00 and came on a 5.25" floppy disk. Unfortunately my computer at that time did not have enought ram to run the program so I never got the chance to even fire it up. I no longer know where the oriinal disk is anymore.

..must have been quite an old version
- MCP 8 comes on a CD
- even MChess 3.12 from 1992 comes on a 3 1/2" Disk (with bad copy protection - will never start again here)

best wishes

If I remember correctly it was soon after the program was created and I think it was in the late 70's or early 80's that it became available.
At the time it was advertised as the most powerful program around.

How much to upgrade from the version I bought in, 1991?

I still have the green 5.25" disk it came on.
"M Chess!"
"By Marty Hirsch"
"Copyright C 1990,91"

It was protected by Everlock.

I know my memory is getting bad but it was such a large amount of money that I am sure that it was $500.00 and not $50.00 but even the lessor amount would have been expensive in those days. I had moved back into the SF Bay Area in 1987 and I had purchased the program way before I moved.

you will also find some nice games playing an old Mchess Pro developer version (8.42 and 8.70) from 1999/2000 with special settings for figure values and kingsafety and mobility.....
( i estimate that versions around 2650-2700 ELO >2GHz AMD 32bit CPU)

Hi Andi,
from SSDF list:
108 MChess Pro 8.0 128MB K6-2 450 MHz 2478 25 -26 753 40% 2549
109 Genius 6.5 128MB K6-2 450 MHz 2477 28 -28 605 48% 2490

and CEGT: Genius 7 2406 25 25 527

So I think MCHess 8 would have a similar rating around 2400

Hi Werner. you want to say that although you test on a state of the art hardware, genius is only doing 2406 ELO and the ssdf had test it on
K6-2 450mhz hardware and it got similar elo.

but the AMD k6-2 450 mhz is way slower than the hardware you use,
or ? alone from the hardware progress one would expect
a higher elo.

this looks somehow strange to me.

Hi Werner,

i'm not talking about the strength of Mchess Pro 8 on a K2-450 Mhz.
I'm talking about Version 8.42 and 8.70 for both i have settings that are stronger than the released (maybe around 70 Elo) Version 8 and my hardware AMD 2400 XP + is 5 times faster than a K2-450 (additional around 150 ELO)

so Mchess 8 ELO SSDF 2478 + 70 + 150 = 2698 = Mchess 8.42/8.70 ELO on AMD 2400 XP + (at tournament time level....)

we can test it ..so choose an opponent you like or two (one with elo 2500 and the other wit ELO 2650-2700) and lets play some games 90+45 or 90+60 on the playchess.com server...
i'm sure mchess beat the 2500 opponent and will give the 2650-2700 ELO opponent a good fight very close...

if i'm right and mchess DOS on 1 cor 2Ghz has nearly 2700 ELO than think about an Mchess who can use 1 Ghz Hash instead of 64 MB who can use many cors than just one and can use the 64 bit and can use the whole endgame tablebases, and can use the today good opening book....

so if marty only transfer it that it can use all this features (without any other improvement to the engine) we will have a 2900+ ELO Mchess at least...(on a fast quad like i7)

so i#m looking forwars to 2010...

Hi Bill,

If my memory serves me correctly I think you probably bought AI Chess, which was the precursor to MChess written by Marty. This was sold for hundreds of dollars due to some marketing agreement entered into by Marty. It didn't sell well so Marty launched MChess in ~1991 at a more reasonable price.

I remember Marty would sell the very latest version of MChess. So some customers would get v 1.18 (my first) and others v 1.23 etc as he made improvements. I think I owned v 1.18 and 1.62. MChess had a really unique style and I'll certainly buy an updated version. I think it had some sort of momentum term that would start to grow when it sniffed an advantage - sometimes it would build on this advantage and the evaluation would explode, other times it would die out when MChess had overextended - great fun to watch.

The original MChess was written on 100% assembler so I hope Marty will convert this to C so that we can have all the usual variations (x64 bit etc).

Happy memories,

Cheers,

Steve
