While I'm continuing to use Nick's ponder-on conditions for the sake of consistency as I run sidebars to his tests, I begin to lean toward Steve's ponder-off warning. It's just easier to preserve conditions that are closer to perfect.

Observations, no particular order:

1. Mephisto Explorer Pro (released 2007) does not provide options for selective or brute-force search. You can't turn off its book. The only way to affect it (aside from time controls) is by turning ponder off.

2. RS 2250 XL (1997) and RS 2200X (1992) both include ponder options, as well as multiple opening books and randomizing.

It hadn't occurred to me that such a wide time period separated these machines. The feature-set decisions are intriguing.

3. Wiki says the original Explorer (2005) and the 2200X are GK 2000 clones.

4. Wiki says (in two different places) that the Explorer Pro is a GK 2100 and a Cougar (1998), and (indirectly) a 2250XL.

5. Wiki says the Mephisto Chess Challenger (2004) is a Centurion (1998) and a President (1993), and a GK 2100 (1993) and a 2250XL, if you dig deeply enough. The Challenger is the least established.

6. I like the Explorer design a lot. The backlit screen is so much easier. The button configuration is pleasantly simple compared to predecessors. The side pockets present a great piece compartment and cat deterrent. I like the rate-yourself component (which shows up on the RS 2250XL as test positions.) It's too bad the extra stuff vanished (brute-v-selective and multiple). With those features included, it would be almost perfect. One could still argue for the Explorer Pro as the best tabletop buy of the 2000s.

On the Cougar you have the A2 to H2 squares under Options. a2 changes to selective or brute force and b2 turns on or off easy mode (turns the thinking on opponents time on or off)
I guess in order to make Explorer Pro seem different to Cougar they turned the a2 to h2 features off or moved some of them to other rows. These two computers are supposed to play identically.

For clone testing Ponder off might be better, but probably not really because with many true clones playing with ponder on, beep at the same time so ponder on helps to raise your suspicions really easily.

Ponder on is a stronger setting so for match play it should always be on. Turning it off weakens the computer's strength.

I have just completed Test Game # 6. Test Game 6 is a match between a French person named Monillaux playing against Alexey Suetin of Russia. This was played at the World Student Games in Lyons, France in 1955.

Barden has the names as Monillaux and V. Suetin. I think he messed the names up. I did some digging and Alexander Suetin (Alexey) did in fact play for Russia scoring 8 out of 10 points. There was a person named Mouillaux who played on Board 2 for France. He only scored 1/2 point in 9 games. So I am guessing the correct name is Mouillaux.

Alexey Suetin's highest rating was ELO 2701 in October 1970. In this Test game he was evaluated at ELO 2625 which I think again fits well.

Here is the Game:

Well after playing the weaker programs first with Morschies reaching approx. 2400+ and Novag Jade scoring ELO 2299, I was then very surprised to see Saitek Corona scoring 2519 ELO!!

This of course made me look forward to trying out first King 2.54. King 2.54 of course stormed past Corona and beat the Grandmaster rating as well scoring ELO 2651! This is the second time that King 2.54 has scored above 2600 in 6 Test Games!

Next came the Mephisto Tournament Machine Vancouver. TM Vancouver I thought played great and finally showed it's capability storming past King 2.54 with at this point the highest score recorded by a dedicated computer of ELO 2709!!

Wow I thought, incredible! Anyway the last 3 to play were Atlanta, Senator and Magellan.

Starting with Atlanta, I very quickly got very excited as Atlanta started picking up max points after max points. Surely I thought there is going to be some mistakes coming up? But no Atlanta shocks the world with a World Champion strength performance of..........

wait for it !! ........

ELO 2806 !!!

So after recovering from this Senator was next to play this Test game. And lo and behold Senator matched Atlanta score for score playing each move identically to Atlanta and also scoring ELO 2806 !!

Last but not least was Magellan. Well by now I expected Magellan to do the same as Atlanta and Senator. And, I was not disappointed. Magellan also scored ELO 2806!!

All three computers played 100% the same moves in this world class performance!.

MM6 and Travel Champion also again repeated all their moves 100%.

I can safely say that besides the enjoyment of comparing the computers play strength against each other and Grandmasters, this test can be used very successfully to detect clones and closely related chess programs.

It is also nice to see that 3 computers have now passed the ELO 2300 barrier as well.

After playing 3 Positional Test games, I am now going to move to the next chapter which covers Attacking Play.

Hi ,

I would like to help you - but I am slightly confused about what setting to use - do you want 30 second average or 21 ply settings(this many ply could take a very long time) ? And so I make the move on the machine then wait for a response - note it - take back (if it is not the best) - and so forth - forcing it to continue after take back ? is that correct ?

Nick, how come none of the three Novag Diamonds are involved in your testing?

Hi Queeg,

With the dedicated computers it is 30 seconds average time. You just have to set up your Igor for example at 30 seconds per move and let him play. Just do take back and manually enter the moves until you get to the start positions.

Hi Steve,

I just have not got to adding more computers yet. Eventually I will add them. If you have any of them then just try it out yourself and post the results here and I will add them to the list.

As it turns out , I did not wreck the 24 MHZ Igor - I had the voltage too low so it would not work -

Here is how he did in the first game - not too bad considering he's a spaz !

Cool, I have updated the Game 1 Table. Excalibur Igor 24 MHz scored 1991 ELO and slots right in behind Novag Jade. Did you set it at 30 seconds per move or 1 minute per move? You are allowed to play Igor at 1 minute per move since it is calculating twice as fast with 24 MHz.
