MCGE Classic London Book v Champion Book
I have just completed another ten game match between the StarDiamond(SD) and the Millennium ChessGenius Exclusive (MCGE) at 40m/2h. This time I set the MCGE to use the Classic London Book and got what I think is a surprising result.
In the ten game against the SD using the Champion book the result was MCGE +5 =5 (75%)
Playing White: +4 =1
Playing Black: +1 =4
ELO: 2364
Against the Magellan at the same time control and same book:
MCGE +7 =1 -2 (75%)
Playing White: +3 -2
Playing Black: +4 =1
ELO: 2397
When using the Classic London Book against the SD
MCGE +8 =1 -1 (85%) A much larger difference than I expected!
Playing White: +5
Playing Black: +3 =1 -1
This gives a rating difference of around 301!
ELO: 2474
This is an extraordinary result for the MCGE and I think it must have had the luck of the chosen openings giving it this much higher rating. I was expecting a figure closer to 2400 at this time control which would still have been a little higher than with the Champion book. Could this be just noise and proving many more games needed or is using the Classic book that much better against computer opponents?

Actually we went through this exercise when the MCGP was released
it was thought that perhaps the two different books would show a significant rating difference
there is a thread about this here somewhere....
IIRC..as it turned out..there was no significant difference when a larger number of games were played against a variety of opponents
my guess is that's what is happening with the MCGE

Yes I actually made those tests with the MCGP against my SD and posted the results here. I started to do the same with the Magellan, but never got round to completing it.
Yes, I would think against a large number of opponents a more accurate figure would be achieved. Unfortunately, I only have two other programs strong enough to offer any form of resistance against the MCGE. I don't think 1800 to 1900 rated machines would offer enough.
Maybe a match with HIARCS set to 2400 might be worth a shot?

I guess you mean playing the Hiarcs PC engine and somehow setting it to play at a weaker level?
sorry I cant opine on that sort of thing..not knowledgable enough about PC chess engines to know if the rating of 2400 is reliable when setting it to play at a weaker level
perhaps others can say if that would be a good test

Unfortunatetly I don't own either a Rev I or II as otherwise would be trying that now.Steve B wrote: Hiarcs does appear in the Rev I and Rev II dedicated computers ,but

I also have no experience of using the PC Hiarcs ELO setting. I do know that it is calibrated to the speed of the PC it's running on but that is all.
I normally prefer playing one dedicated against another, but that is the problem with having only one very strong machine like the MCGE. The other option is to lower it's speed to 50Mhz and pit it against my Saitek Cosmos which is rated about 2020, or maybe the Talking Chess Academy at 1900 or maybe at a push the Grandmaster Excalibur at 1800+

yes I do tooYarc wrote:

there seems to be a new trend where dedicated computers are being matched up against old and new PC engines
not my sort of thing but I guess others find it interesting

I don't see why you cant at least try that
if the results between the two books are still as striking as you find them to be at this point ..then we know you might be on to something very interesting

The only thing about reducing the speed of the MCGE is that it will then behave more like its predecessors. Having already played the MCGP against the SD, I might see a similar set of results. Perhaps then, the MCGE at 50Mhz against the Talking Chess Academy and Excalibur Grandmaster would be more interesting?Steve B wrote: I don't see why you cant at least try that

you are doing all of the hard field work

Thanks. It's a very time consuming thing so don't expect results anytime soon, but it might prove interesting as you say. I may hold back until the Lang update comes through at the end of the month as this is likely to improve its rating a little and I will be eager to install it.Steve B wrote: your call Ray

very good
if your results still show a big difference in rating ...then perhaps in the spring we could play an online match (Lichess) and i'll operate the Rev I or Rev II Hiarcs
Rev I Hiarcs has an SSDF Rating of ...2771(40/2)
Rev II Hiarcs has an SSDF Rating of ...2923(40/2)

I notice that so far on rating lists the MCG and MCGP are listed but not the MCGE. I guess it's too soon, not enough results.

I think Hiarcs at full strength on the Revelation 2 would be a walkover for Hiarcs. I played a short match between Hiarcs on a palm tungsten at 200mhz against chess genius on a tablet at 1.2ghz. Hiarcs won 5-1 with 2 lucky draws for the chessgenius.
Hiarcs 1% on the Rev 2 might be more interesting, its rated at 2369 on the wiki and none of the traditional dedicated comps have acquitted themselves at all well against it.
Of course the big match would be against the wundermachine for the strongest lang classic dedicated of all time title! Personally I don t think the title would change hands, but it would be a good measure of whether the new lang has made any progress.

I matched it against two Lang Engines
it defeated the Rev II London 4-1 and
ate the MCG's lunch at 3-0
it even beat the MCG at Knight odds(but lost at Rook odds)
Matches can be found here:

Perhaps your right and a better match up Vs. the MCGE would be Wunder Boy

Steve, I know you're not interested in PC engines v dedicated. I don't really like the idea. However, out of curiosity started a game with PC Hiarcs set to 2400 ELO. The first game and probably the last, is showing Hiarcs looking 3 to 4 extra ply ahead and gaining an early advantage. Doesn't seem right somehow, but then what did I expect ? I don't think this is proving anything. I'll continue to the end, but not convinced this was such a good idea.Steve B wrote:Ah Yes..the legendary WunderMachinelexman wrote: Of course the big match would be against the wundermachine for the strongest lang classic dedicated of all time title!

I've been forced to abandon the game. Had paused it from PC Hiarcs menu and put my laptop into standby. However, on resuming Hiarc's clock ended up at zero time when it should have been close to 2 hours, and it lost!? Well, I wasn't convinced it was a good idea, and this has helped confirm it!
