Hi BishopBlougram. I'm sure you have but did you make sure ECO mode was turned off?
Why not try tournament level 2 to see if that is better.

I'm guessing that there are enough differences between MCG and MCGP apart from processing speed that they'd have to be considered quite different engines.

They both have versions of the Android ChessGenius program. The MCG has version 2.6 and the MCGP has version 3.0. You can read the differences here http://www.chessgenius.com/android/index.html

Here is the first game of my 10 game match between the MCGP and Stardiamond. In this match the MCGP is set to use the "London" book.

In this game they followed the Caro-Kann, Panov-Botvinnik Attack. The MCGP went out of book at move 8 whilst the SD hung on until move 14. This certainly gave the SD some extra time on the clock. The result was a crushing win for the SD, I resigned for the MCGP after only 27 moves, it was a hopeless case for the newcomer.

[Event "40m/2h London book"]
[Date "2016.10.16"]
[Round "1"]
[White "SD"]
[Black "MCGP"]
[Result "1-0"]
[ECO "B14"]

1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nc3 e6 6.Nf3 Bb4 7.cxd5 Nxd5 8.Qb3 Nc6 9.Bd3 Qb6 10.Bd2 Nxd4 11.Nxd4 Qxd4 12.Bb5+ Kf8 13.O-O-O Bxc3 14.Bxc3 Qxf2 15.Qb4+ Kg8 16.Rhe1 Qxg2 17.Qd6 Qg5+ 18.Bd2 Qf6 19.Qxd5 h5 20.Qc5 e5 21.Rxe5 Be6 22.Bc3 Qh6+ 23.Kb1 b6 24.Qe7 Qg6+ 25.Ka1 Qf6 26.Qxf6 gxf6 27.Rg1+ 1-0

Final position:
[fen]r5kr/p4p2/1p2bp2/1B2R2p/8/2B5/PP5P/K5R1 b - - 1 27[/fen]
No hope for the MCGP as black. All of whites pieces are in prime position for a deadly blow.

This is not a good sign for the MCGP, we witnessed a crushing blow in the previous match for the MCGP, but this game takes the trophy. The SD shows what it can do against inferior play.

MCGP sent to bed without supper Regards

More games like this and the MCGP is going back in its box and stuffed in the loft.

Any hope? Regards

A disappointing start to the match, maybe it will do better in the next 9 games. Don't forget, it did win the previous 10 game match using the Human book albeit by less than was hoped. But I do think that using the Android version of the Genius program with knowledge stripped out has not done it any favours, at least not at longer time controls. My Stardiamond will not be relegated to the attic yet!

Maybe the MCGP's forte is active chess with the Human book?

Ifs buts and maybes regards

Here is game 2 of my 10 game match.

Mirroring the first match where the Stardiamond won the first game and lost the second:

They played the English, Sicilian reversed and both were out of book at move 8.

[Event "40m/2h London book"]
[Date "2016.10.17"]
[Round "2"]
[White "MCGP"]
[Black "SD"]
[Result "1-0"]

Final position:
[fen]5k2/8/3N1PP1/3b2K1/1n1B4/8/8/8 w - - 7 61[/fen]
The SD resigned here. I knew it was done for but wanted to see when it would give up.

The MCGP played solidly in this game gaining an early advantage and was able to hold on to it, but can it keep up the pace?

Level pegging regards

Just wondering - for the sake of completeness - whether it would be worthwhile conducting a 10 game match with book openings disabled on both the MCGP and SD. What do you think?

Pondering no book regards

It could be interesting perhaps to pick 5 opening positions that are equal but are in neither computers books and get them to play both the black and white sides of the same position. If chosen well that would give a real insight into the programs themselves.

I think this is what the BT2650 and BT2450 tests are about, ie,
estimating the accuracy of the search function. I don't own an MCGP
so I'm waiting for someone to run these tests.
I notice just now the MCG shows 2216 on the BT2650 test. These
tests have shown themselves to correlate fairly with with actual strength.
