The programs come out of the opening exactly evens at move 13 and a sort of Berlin Defence/Endgame open variation ensues. The game remains even until move 40 when the Fidelity EAG begins to lose the thread and the CG Pro begins to assert its endgame strength and calculating clout in an endgame of bishop rook plus four against knight rook plus four.
So the CG Pro leads 3-2 with one game to go, can the fidelity pull back the last game to draw the match?

The CG Pro got a slight edge out of the opening but by move 30 Stockfish has the EAG ahead by about half a pawn based on its imposing 3-1 queenside pawn majority. The decisive blunder is 64...Rc3 which changes the evaluation from -2.9 in blacks favour to +3.3 in whites. Thus the final match score is 4-2 in favour of the CG Pro. I make this a performance rating for this match of 2438 for the CG Pro. The two machines are generally very closely matched and in this short series it was the CG Pro,s endgame calculation grunt that appeared to give it an edge in some fairly long games. Over a much longer series thing could easily be more even.

Thanks for the mini-match
even more evidence that the CGP plays a solid 2400 at 1 Min

the picture is becoming clearer:
30 Sec -2500+
1 min -2400+
3 min-2300+

an amazing reduction in strength as the TC Increases

If the pool included human players, the numbers would probably be lower. I'm a 1900 (USCF) player and my score after 8 G30 is 50% (three wins, one draw and three losses). Curiously, all of my wins were tactical melees whereas my losses were me being squeezed to death in predominantly positional games.

Hi Steve,

I think this is looking about right. I have been delayed in starting my matches against the Magellan as unfortunately just lost my Mum which is devastating to say the least. It will be good to start the match to take my mind of things but so much red tape to get through!

Managed to get around to playing the first of ten games between the MCGP and Magellan at 40m/2h using the Human book. I have set the Magellan to use its tournament book for maximum strength, but less variation in opening play.

In this game they played the Reti opening with the Magellan out of book at move 4 whilst the MCGP held on until move 6:

Final position:

Game over, Magellan announced mate in 5!

The Magellan dominated this game and the MCGP was powerless as black marched its pawns into the enemy camp.

I'll start the next game as soon as I can.

My MCG Pro arrived today!

First impression:

What I am really liking from the start is that when powering it from mains I don't have to keep pressing the Light button every so often to see the display, and that it no longer shuts down whilst analysing a move! The much lighter touch of the chess board making it so much easier to enter moves is a real bonus. To my mind these are the most annoying aspects of the earlier MCG model.

I notice that the Human book is selected by default which makes me think that this is considered the best/strongest option by Millenium, don't know, time will tell.

Now I must decide which of my older machines to pit the MCG Pro against first. I am currently thinking the Stardiamond followed by the Magellan and then the Cosmos. The StarDiamond won the ten game match against the MCG by one point. I don't think it's going to do so well against the MCG Pro, but we shall see.

Either way, its going to take a while for two ten game matches, one match using the Human book, the other using the London book. Maybe I will see a difference in performance between the books or maybe not. Either way, it will be interesting. I will keep you posted when I start the matches and as they progress.

Regards
Ray.

Ray & Steve,

Thank you for putting the MCG Pro thru its paces and posting so many games. I'm considering upgrading my MCG to the Pro.

A couple of quick questions about the Pro:

1. Is the LCD screen improved compared to the MCG, or does the backlight just remain on with the Pro?
2. Do you feel that the squares are more responsive?
3. Is the power adapter cord longer?

Just kidding about #3, but I am interested in the LCD and response of the squares...
