Here is the final game of my 10 game match between the MCGP and SD at a time control of 40 moves in 2 hours using the London book:

They played the Pirc-Robatsch opening. The MCGP was out of book at move 7 and the SD at move 10.

Final position:
[fen]8/8/8/1k6/3R4/3K4/8/8 w - - 5 74[/fen]
The SD resigned here.

So, the last game goes to the MCGP making the final score 7.5 - 2.5 to the MCGP. That gives the MCGP a rating of 2366 in this match.

Some of the games were pretty close with both computer's evaluations jumping plus and minus and each side gaining and losing the advantage. I don't think the 2366 rating achieved in this match is reliable when considering the first game which the MCGP lost badly and had the same opening been played again the result of this match could have been 2283. However, it does show that the MCGP can perform well at this time control.

Is the London book better? All I can say is that in this small match of 10 games against the Stardiamond at a time control of 40 moves in 2 hours it appears to be.

Judging by the results posted above by Sargon1972 and steffen I'm wondering if the MCGP has a higher rating for active chess (game in 30 minutes) with the Human Book(?) than it does at longer time controls with either book.

Anyway, I'm happy with the result the MCGP has achieved so far.

Next match with Magellan Regards Ray

Hello Ray,

As i wrote before in test games the rating of the CGPro was after 120 games+- 2403 ! in active chess
The SD did lost 10-0
Magellan did lose 7,5-2.5 Atlanta the same ore 7-3 all points scored where draws so i expect to see the same result in 40-120 games vs Maggi
I wrote also that the rating mine idea would drop to 2350+- of the CGPro

so 2366 elo is around that 2350 +- not bad for a old program in new hardware

Also it depend heavy on what opening the CGPro play
There are also bad lines in both books ,also the CGPro do not understand what is needed in that opening
Nevertheless ,it is a strong beast plastic beast ,and for a fair price also

Have fun with your next games

Hello Kr,Hans.
I agree with you, and also believe the final rating of the CGPro will end up around the 2350 +- area. I think its a very good machine for the price and looking forward to the next two matches I am going to play between the CGPro and Magellan, again comparing the Human book and the London book at the longer time control. I think we need more games at the longer time controls to obtain a more accurate rating.

Regards Ray

Great result at the DACh tournament for the CG Pro. I make it a 2560 performance including wins over the R30 2.5 and 2.23. Overall the rating seems to be closing in on the old Selective Search rating of 2357 for the genius on a palm zire 126mhz. I may try the Pro in a match against the Fid EAG v11 72mhz at 1 min per move starting soon. This would be interesting as both machines have BT 2630 scores of 2291.

I may try the Pro in a match against the Fid EAG v11 72mhz at 1 min per move starting soon. This would be interesting as both machines have BT 2630 scores of 2291.

it seems the faster the time control the stronger it plays
from a 10-0 Vs the Star Diamond at 30/sec move(2583 Performance rating)
to a solid 2400-2500 rating at 1 min per move Vs the R40 (and your games)
to mid 2300's at 40/2
you don't normally see such a wide margin between faster/slower time controls
more normal would be a diff of 50-75 pt difference

Hmmm Regards
Steve

Hello Steve,

To less games are played , but in mine 40/120 games it was +- same rating as in 30 sec a move ,so be patience at the end the CGPro will be 2350 elo+- at all levels

In the first 10 game match against the Stardiamond at 40m/2h using the Human book the score was 6-4 giving the CGPro a rating of only 2245. Maybe this was just bad luck on the CGPro's part to end up in openings it did not handle so well. Another 10 game match with the same settings may reveal a different result. For the Stardiamond, I think the longer it stays in book the stronger it is, but I'm wondering if the CGPro is better when it leaves book openings earlier. It will be interesting to see how well the CGPro does against the Magellan at this longer time control. The previous CG only managed a draw against the Magellan.

Maybe the Human book will prove the best option overall after more testing?

So to the opening game of a short six game match between the CG Pro and the Fid EAG v11 72mhz. I will take the elo of the Fidelity as 2315 which is an average of the tournament and active Wiki gradings. Both Comps have BT 2630 ratings of 2291 which hopefully will make for a close and interesting match. CG Pro Hiarcs book eco off throughout

[Sargon1972]

Hello ,

Are u sure that the V11 is on Tournament book ,and not all openings on?

Option , 2x square F1 must be out ,then u use the TM book when it is on the V11 play all openings and make him weaker due this openings

Some very interesting results for the MCGP, thanks for the effort of running the games, I know it's a labour of love.

Stockfish shows the machines coming out of the opening evens at move 16.
However the CG Pro definitely missed a win later in the game. After 61...Kg8 it has the Pro as white on plus 10. However it misses the winning maneuverer of activating the R to C6 and the 7th rank at various points and in playing 73 Bx h4?? instead of R C6 the evaluation goes from plus seven to equality leading to a draw.
The CG Pro leads the match 1.5 -.5 after two games

Here is game three of the match CG Pro versus Fid EAG v11

Kf3 59. Qe5 Kf2 60. Qf4+ Kg2 61. Qe3 e1=Q+ 62. Qxe1 1-0

So the EAG steams back to even the match. The decisive mistake was 45...KxF3?? when white Queens first and the evaluation jumps to plus 10 for white, 45 ..H5 had to be played when black also Queens with an even position. So with 1.5-1.5 and at this stage the match is as close as expected

A long and remarkably accurate game by both machines, stockfish unable to find any glaring errors for either machine and both only differing by 7 centipawns from what stockfish considered best play. The position is equal out of the opening at move 15.So with only two games to go and a 2-2 score can either machine make a break through in what contiues to be a close match?

Group B:
1. Fidelity Sensory 9 CB 16 8 MHz 5.5 points out of 7
2. SciSys Turbostar 432 4.5
3. Radioshack 1900L 4.5
4. Mephisto Manhattan 4 MHz 3.5
5. Mephisto III-S Glasgow 3.5
6. Excalibur Alexandra 3.0
7. Sphinx Concerto 2.5
8. Novag Constallation 2.0

Small correction:
The Constellation 2.0 mhz had only 1.0 point: a win in the last round against my very modest performing Concerto. But I had a small consolation: the Concerto was the only one to beat the winner (sensory 9 8mhz).
