10 Game Match beween TheKing and ChessGenius Android

I have played a 10 game match between Millennium’s TheKing module set to Normal play style, Master book and all other settings at their defaults, against Chess Genius for Android running on my Galaxy Tab A8 with a time control of 30 moves in 30 minutes then all remaining moves in 30 minutes.

I know that matches have been performed with TheKing module against Millennium’s Chess Genius module and TheKing dominated, even when set to a much lower speed. In my case, my tablet is a 64-bit, 8 core processor running at 2GHz per core and has 4GB of memory, although I believe Chess Genius for Android only uses a single core (please correct me if wrong, but it’s not advertised as being multi-core) compared to the King module which is a 32-bit processor running at 300MHz. From these figures, TheKing is running on a computer in the order of about 7 times slower. I’m not sure how much Chess Genius benefits from being a 64-bit program, but that may make the speed difference even more. I also don’t know how much different the Chess Genius for Android engine is compared to the one in the Millennium Chess Genius module; apart from it being 64-bit. But I think we would all agree, that Chess Genius Android has the advantage in this match for processing power!

Maybe the outcome will be similar to the matches between Chess Genius and TheKing modules from Millennium especially as I believe Chess Genius does not scale up so well on faster hardware.

What are your predictions for the outcome? Will Chess Genius win with the extra processing power, or will TheKing show it can still perform against it?

Games will be posted shortly...

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 1 of 10

Well, the first game was a draw. They played the English, symmetrical variation opening and up until move 50 TheKing was doing quite well but this advantage gradually reduced into a drawn endgame which I played out to the bitter end!

According to Deep HIARCS 15.1 TheKing(White) made 13 inaccuracies whilst Black made 12. There were no blunders:

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 2 of 10

Well, another draw! Is this a sign of what’s to come?
They played the French, Tarrasch, open variation and the game was pretty much even throughout ending in 3-fold-repetition.
This time there were far less inaccuracies with Chess Genius(White) making 4 and TheKing making 5. Again, no blunders but Chess Genius so far making 1 less inaccuracy per game.

[Event "30/30 Rest 30 mins"]
[Round "2"]
[White "Genius"]

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 3 of 10

The draw pattern is broken and TheKing takes the first win.

[Event "30/30 Rest 30 mins"]
[Round "3"]
[White "TheKing Normal"]
[Black "ChessGenius Android on Galaxy Tab A8"]
[Result "1-0"]

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Nde2 Nf6 7.g3 O-O 8.Bg2 d6 9.O-O Bd7 10.h3 Rc8 11.a4 Ne5 12.b3 Qa5 13.Bd2 Qc7 14.Re1 Be6 15.Ra2 Qd8 16.Nd5 Qd7 17.Ndf4 Qc7 18.Nxe6 fxe6 19.Nd4 Qd7 20.Qe2 Nh5 21.Qe3 a6 22.c4 Nf7 23.Nc2 Bh6 24.Qe2 e5 25.Bxh6 Nxh6 26.Nb4 Nf6 27.Qd2 Nf7 28.Nd5 Nxd5 29.exd5 Rc5 30.a5 Nd8 31.h4 Qg4 32.Kh2 Rf7 33.Bh3 Qf3 34.Qb4 Rf8 35.Rd2 h5 36.Re3 Qf7 37.Qb6 g5 38.hxg5 h4 39.Rxe5 hxg3+ 40.fxg3 dxe5 41.Qxc5 Qh7 42.Qc7 Qg7 43.Re2 Qxg5 44.Qxe5 Qxe5 45.Rxe5 Kf7 46.Rf5+ Kg8 47.Rxf8+ Kxf8 48.Bd7 Nf7 49.c5 e5 50.Bc8 Nd8 51.Kg2 Ke7 52.b4 Ke8 53.b5 axb5 54.Bxb7 b4 55.Bc6+ Nxc6 56.dxc6 Kd8 57.a6 Kc7 58.a7 Kxc6 59.a8=Q+ Kxc5 60.g4 b3 61.Qa3+ Kc4 62.g5 b2 63.Qxb2 Kd5 64.g6 Ke6 65.Qb3+ Ke7 66.g7 Kf6 67.g8=Q Kf5 68.Qf3# 1-0


They played the Sicilian, Accelerated Fianchetto, Exchange variation and all was level after White’s move 14.Re1:


From here TheKing slowly at first but then positively outplayed Chess Genius.
According to Deep HIARCS15.1 TheKing(White) made 1 mistake and 2 inaccuracies whilst ChessGenius made 2 mistakes and 6 inaccuracies.

We know TheKing is good so maybe this result isn’t a surprise. Lets see how game 4 goes.

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 4 of 10

Another win for TheKing!

[Event "30/30 Rest 30 mins"]
[Round "4"]
[White "ChessGenius Android on Galaxy Tab A8"]
[Black "TheKing Normal"]
[Result "0-1"]

1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 Rb8 6.Nge2 d6 7.O-O b5 8.a3 Bd7 9.Bf4 Nf6 10.Bg5 h6 11.Bd2 e6 12.b4 O-O 13.Qc1 Kh7 14.bxc5 dxc5 15.Be3 Qe7 16.h3 Nh5 17.Rb1 b4 18.axb4 cxb4 19.Na4 Rb5 20.Nb2 Rc8 21.Qd2 e5 22.g4 Nf4 23.Nxf4 exf4 24.Bxf4 Bc3 25.Qe3 Bd4 26.Qg3 Ne5 27.Be3 Bxe3 28.Qxe3 Rxc2 29.Qxa7 b3 30.f4 Nc6 31.Qe3 Qa3 32.Nc4 Qa2 33.Bf3 b2 34.e5 Ne7 35.f5 gxf5 36.gxf5 Rb8 37.f6 Rg8+ 38.Kh1 Nf5 39.Be4 Rg5 40.Nd6 Kg8 41.Nxf5 Bxf5 42.Bxf5 Rxf5 43.Rg1+ Rg5 44.Qf3 Qa5 45.e6 Qc7 46.Rxg5+ hxg5 47.exf7+ Qxf7 48.Qa8+ Kh7 49.Qe4+ Kh6 50.h4 Rc1+ 51.Kg2 Rxb1 52.hxg5+ Kxg5 53.Qe5+ Kg6 54.Qg3+ Kxf6 55.Qf4+ Kg7 56.Qe5+ Qf6 57.Qc7+ Kg6 58.Qg3+ Qg5 59.Qxg5+ Kxg5 60.Kf3 Rd1 61.Ke4 b1=Q 62.Kd5 Qxd3+ 63.Kc5 Qc2+ 64.Kb6 Rb1+ 65.Ka5 Qa2# 0-1


According to DH15.1 (Deep HIARCS 15.1) CG(ChessGenius) made 1 blunder and 8 inaccuracies whilst TheKing made 1 mistake and 2 inaccuracies. These figures explain the result but where did it go wrong for CG? According to DH15.1 all was level after Black’s move 39...Rg5:

Black has a pawn poised for promotion on b2 tying up White’s Rooks but White’s pieces are also in strong attacking positions. Here, White moved 40.Nd6?? DH15.1 after about a minute on my desktop looked 24 ply ahead and gave an eval of -6.26. One better continuation would have been:
40.e6 Bxe6 41.Nd6 Kh8 42.Nxf5 Bxf5 43.Bxf5 Rc1 44.Qe8+ Rg8 45.Qe3 Rg5
Resulting in the following position with White to move and the position level:


Chess Genius, despite examining over a million positions per second, and often 2 or 3 ply extra ahead than TheKing’s displayed values, does not seem to comprehend the positions as well as TheKing.

TheKing is not able to make the same moves as DH15.1 but does take advantage and from here on dominates the rest of the game.

Current Score 3 - 1 to TheKing

On to the next…

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 5 of 10

Another win for TheKing!

They played the Four Knights, Belgrade Gambit and it looks like TheKing’s Master book is better than the one in CG. I’ve noticed in this match that CG is out of book far sooner than TheKing, although as we know book opening size is not always indicative of playing strength, but in these games it has certainly helped with TheKing’s clock!

[Event "30/30 Rest 30 mins"]
[Round "5"]
[White "TheKing Normal"]
[Black "ChessGenius Android on Galaxy Tab A8"]
[Result "1-0"]

1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5 Nxe4 6.Bc4 Be7 7.O-O O-O 8.Re1 Nf6 9.Nxe7+ Nxe7 10.Qxd4 Nc6 11.Qh4 h6 12.Nd4 Nxd4 13.Qxd4 d5 14.Bd3 c6 15.b3 Re8 16.Rxe8+ Nxe8 17.Bf4 Be6 18.Be5 Qb6 19.Qh4 Qc5 20.Re1 a5 21.c3 Qa3 22.Bb1 a4 23.b4 Qb2 24.Qd4 Rc8 25.Qd3 Kf8 26.Qe3 Kg8 27.Bd4 b6 28.Qd3 g6 29.Qe3 c5 30.bxc5 bxc5 31.Bxc5 Kh7 32.Bd4 Qb8 33.Bd3 Qc7 34.Be5 Qe7 35.Qd4 Ra8 36.Qb4 Qxb4 37.cxb4 Ra7 38.Bb5 Ng7 39.a3 Nf5 40.Rd1 h5 41.h3 g5 42.Rc1 Bd7 43.Bd3 Kh6 44.b5 Rb7 45.Rc5 Be6 46.Bc2 d4 47.Bd3 Ne7 48.Bf6 Nd5 49.Bxd4 Nf4 50.Be4 Rd7 51.Be3 Bd5 52.Bxf4 Bxe4 53.Rxg5 Kh7 54.Rxh5+ Kg6 55.Rh4 Kf5 56.b6 Rb7 57.Bc7 Bc2 58.Rh6 Bb3 59.g4+ Kg5 60.Rc6 f6 61.f4+ Kg6 62.g5 Kh7 63.Rxf6 Kg8 64.f5 Bc2 65.Rg6+ Kh7 66.Be5 Bxf5 67.Rh6+ Kg8 68.g6 Bxg6 69.Rxg6+ Kf8 70.Kf2 Ke8 71.Bc7 Kf7 72.Rg1 Ke6 73.h4 Kd5 74.h5 Kc4 75.h6 Rxb6 76.Bxb6 Kb5 77.Rc1 Kxb6 78.h7 Kb7 79.h8=Q Kb6 80.Qb8+ Ka5 81.Qa7+ Kb5 82.Rc5# 1-0


The first position where CG made a poor move is in the opening. After making a novelty with 10… Nc6 (theoretical move is 10…d5!) play followed 11.Qh4 h6? (See diagram)

This is not good as it weakens the King’s line of defense. Better would have been to block off White’s Bishop on c4 with 11…d5

Maybe if it had looked far enough ahead TheKing may have seen the following attacking sequence: 12.Bxh6 d5 13.Qg5 threatening mate on the next move, 13…Ne8 the only sensible option, 14.Bxd5 gaining a pawn, 14…Qf6 15.Bxc6 bxc6 16.Qxf6 Nxf6 17.Bg5 and White is in a good position.
However, this is academic because it made the move 12.Nd4.

An interesting position occurred after TheKing's move 22.Bb1 giving this position:

Here, CG replied 22…a4?! To which TheKing moved 23.b4 and Black’s Queen is now almost hemmed in with only one slow escape route! This is something I noticed that TheKing was able to often achieve against CG on the Millennium unit, so an indication perhaps that CG for Android is not so different which I suspected.

Play continued with TheKing outplaying CG. Here is another example of a bad choice of moves for CG:

In this position CG moved 36…Qxb4?! To which White replied 37.cxb4 Now White has a passed pawn. After this, TheKing’s play was strong enough to sail home to victory. Not always perfect, but of course it’s not as powerful as DH15 on my PC!

In this game TheKing made 2 mistakes and 3 inaccuracies whilst CG made 2 mistakes and 12 inaccuracies.

So far, TheKing has 3 wins and 2 draws, still time for CG to win.

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 6 of 10

In this game the Old Benoni, Franco-Benoni Defence was played. TheKing wins another game, it’s on a winning streak making this 4 wins and 2 draws.
[Event "30/30 Rest 30 mins"]
[Round "6"]
[White "ChessGenius Android on Galaxy Tab A8"]
[Black "TheKing Normal"]
[Result "0-1"]

1.e4 e6 2.d4 c5 3.d5 exd5 4.exd5 d6 5.Nf3 Be7 6.Bb5+ Nd7 7.O-O Nf6 8.Re1 O-O 9.Na3 a6 10.Bd3 Nxd5 11.Bxh7+ Kxh7 12.Qxd5 Nf6 13.Qd3+ Kg8 14.b3 d5 15.Bb2 b5 16.Nb1 Re8 17.Nbd2 c4 18.bxc4 bxc4 19.Qc3 Bd7 20.Ba3 Bxa3 21.Rxe8+ Nxe8 22.Qxa3 Nc7 23.Nd4 Nb5 24.Qc5 Qf6 25.N2f3 Rc8 26.Qxd5 Be6 27.Qe4 Rd8 28.c3 Nxc3 29.Qe3 Rxd4 30.Nxd4 Qxd4 31.Qxd4 Ne2+ 32.Kf1 Nxd4 33.Rc1 Kf8 34.Ke1 Ke7 35.Kd2 Kd6 36.Re1 a5 37.f3 Kc5 38.h4 Kb4 39.Re3 Nf5 40.Re4 g6 41.Kc1 Ka3 42.Kc2 Bd5 43.Re1 Nxh4 44.Re2 Kb4 45.Rd2 Nf5 46.Kb1 Kc5 47.Kb2 Nd4 48.Rf2 a4 49.Rf1 a3+ 50.Kxa3 c3 51.Rc1 Ne2 52.Rc2 Bc4 53.Rxe2 Bxe2 54.Kb3 Kd4 55.Kc2 Bc4 56.a4 Bb3+ 57.Kxb3 Kd3 58.f4 c2 59.Kb2 Kd2 60.Kb3 c1=Q 61.Kb4 Qc6 62.g4 Kd3 63.Ka5 Kc4 64.f5 Qb7 65.f6 Qa7# 0-1

In the following position at move 23 both sides have equal value in material, Black has a Bishop and Knight whilst White has two Knights. Black (TheKing) may have a slight edge according to DH15:

Maybe there is some chance of White starting a King-side attack if he positions pieces on this side of the board. However, CG seems to want to maintain a presence on the Queen-side. The problem is it moved 24.Qc5? This leads to material loss which TheKing could see but alas CG could not. The game continued 24…Qf6 25.N2f3 Rc8 26.Qxd5 Be6 27.Qe4 Rd8 28.c3 Nxc3 29.Qe3 Rxd4 30.Nxd4 Qxd4 31.Qxd4 Ne2+ 32.Kf1 Nxd4 and now Black is up a pawn and has a very good winning advantage, which it achieves.

It seems that TheKing is able to ‘see’ more than CG despite the much lower speed of the machine, impressive!

CG made 1 mistake and 8 inaccuracies whilst TheKing made 3 inaccuracies and no mistakes.

Current score is 5 – 1 to TheKing. So now CG cannot win the match, at best make it a draw.

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 7 of 10

I think this game is the most impressive and is also the shortest game in the match at 53 moves.
It’s another win for TheKing and it’s pretty much one-sided from the start!

They played the Caro-Kann, Advance variation with TheKing(White) this time making a novelty move in the opening with 10.a4 (the theoretical move is 10.Ng3!):

The game continued 10…Nb4 11.a5 Nc8?! Run away and hide! Surely, 11…N6d5 would be positionally stronger?
TheKing is not without making inferior moves. Take the following position after move 22:

Here, TheKing with the white pieces is a pawn up and has two Bishops compared to Black’s Bishop and Knight. However, Black’s Knight on c8 is not doing much, and also Black’s Rooks are tied up. Here, TheKing played 23.Bd2?! But 23.d5 would have been much better and more in the style of TheKing’s dynamic play I would have thought. I guess TheKing was planning an attack on the Knight on b4.

Here is the position after TheKing’s 33rd move:

Black is up by a pawn but White’s position is much stronger! CG’s King on b8 doesn’t look safe but to make things worse it moved 33… Kc7?! White only needs to advance the Pawn on d4 and Black’s King is exposed! Well, TheKing did not make this move straight away, but it was only a matter of time before it did and CG suffered as a consequence. Here is the final position:

I did not expect to see a win like this, Black’s Rooks still on their original squares and Black’s King in the center checkmated!

In this game TheKing made 4 inaccuracies whilst CG made 2 mistakes and 10 inaccuracies.

Very good play by TheKing, very poor for CG in my opinion. It does look like CG on Android is still not scaling up well on faster hardware, and possibly not benefiting much or any from being a 64-bit program? Am I being too harsh? After all, running on Pentium PC it beat Kasparov with normal time controls. It’s certainly way stronger than me, so I’m not saying it isn’t good, it’s just that TheKing is so impressive.

Score now 6 – 1 to TheKing. This is looking very one sided!

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 8 of 10

In the following game the advantage swings from one side to the other for about half the game then one side takes over. You can probably guess which.

They played the Queen’s Gambit Declined with TheKing deviating at move 5 from the following position:

Here, the preferred move is 5…b5! But TheKing played 5…Nf6!? In keeping with it’s style, speculative and exciting.

There were two blunders in this game one from each side. The first blunder was made by TheKing in the following position:

CG had just made the questionable move 49.Kg3?! Possibly after the pawn on h5. Better would have been 49.Nc1 preventing the advance of Black’s passed pawn on b4. But to benefit from this move does require looking further ahead then CG could probably manage. However, TheKing responded with 49…e4?? Giving up a pawn bringing the position level again.

The second blunder was by CG in the following position:

Black had just played 62…Kf5 and CG responded with 63.Nc5?? Probably to support advance if the e5 pawn. The better move is 63.Nc1 to eventually reach and protect the pawn on g2, but it’s academic with Black in such a strong position. From the blunder onward TheKing pretty much played the best moves to victory.

So not perfect play with CG making 1 blunder and 12 inaccuracies and TheKing making 1 blunder and 9 inaccuracies. But a win is a win with the score now 7 – 1 in favour of TheKing.

Re: 10 Game Match beween TheKing and ChessGenius Android

Game 9 of 10

Another win for TheKing! After the first 25 moves, TheKing’s advantage started growing rapidly and CG didn’t stand a chance!

They played the Centre game with TheKing playing the white pieces.

[Event "30/30 Rest 30 mins"]
[Round "9"]
[White "TheKing Normal"]
[Black "ChessGenius Android on Galaxy Tab A8"]
[Result "1-0"]

1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qa4 Nf6 5.Nf3 Bb4+ 6.c3 Bc5 7.b4 Bb6 8.b5 Ng4 9.bxc6 Nxf2 10.Rg1 dxc6 11.Nbd2 Nd3+ 12.Bxd3 Qxd3 13.Rf1 Qxc3 14.Rb1 Be6 15.Bb2 Qe3+ 16.Kd1 O-O 17.Re1 Qd3 18.Qc2 Qxc2+ 19.Kxc2 Bxa2 20.Ra1 Be6 21.Nd4 Rfe8 22.Nxe6 Rxe6 23.e5 Rh6 24.h3 a6 25.Ne4 Re6 26.Rad1 Rae8 27.Rf1 a5 28.Rf3 Rg6 29.g4 Rge6 30.h4 R6e7 31.g5 Ba7 32.h5 Ra8 33.h6 Bb6 34.hxg7 Re6 35.Rd7 Kxg7 36.Rfxf7+ Kg6 37.Bc1 Rd8 38.Rg7+ Kf5 39.Ng3+ Kg4 40.Rxd8 Kxg3 41.Rxh7 Bc5 42.Rxc7 b5 43.Rf7 a4 44.Rf6 Re7 45.g6 b4 46.Rxc6 b3+ 47.Kb2 a3+ 48.Kxb3 a2 49.Kxa2 Ra7+ 50.Kb3 Rb7+ 51.Kc4 Bb4 52.Bh6 Ba3 53.g7 Rxg7 54.Bxg7 Be7 55.Rd1 Kf3 56.Rf6+ Kg2 57.Rg6+ Kf2 58.Kd3 Bh4 59.Rgg1 Kf3 60.Rdf1+ Bf2 61.e6 Kf4 62.Rxf2# 1-0

There was a time in this game where CG had a better position. For example, in the following position it is Black to move:

CG is playing with the black pieces and its Queen and Bishops are in aggressive positions. White’s King is stuck in the middle of rank one and Black only needs to castle queen-side to bring a Rook into action pinning White’s Knight on d2. However, rather than a Queen-side castle, CG castles King-side 16…O-O?? The first and only blunder of the game.

In total White(TheKing) made 1 mistake and 4 inaccuracies and Black 1 blunder, 1 mistake and 9 inaccuracies.

Score now 8 – 1 in favour of TheKing.
