PocketGrandmaster v2.1

K. Skibbe & F. Schneider

Pocket PC

 

This version of PocketGrandmaster is certainly the best chess program currently available for the Pocket PC. The variety of features makes this program ideal for the advanced chess player who really wants to work with this program. For example, it has an analyzing feature and a training mode, that you can use for solving test problems and positions. PGM includes four very good chess engines: Gromit, SOS, Ruffian and Fruit. The very strong engine Fruit can’t be found on the main download page, but is available under: http://www.pocketgrandmaster.com/english/FruitPGM.zip Each available engines has it's own character. The open source Fruit-engine of Fabian Letouze is strong overall and probably the strongest chess playing engine next to Hiarcs, Thinker, Toga (CEBoard) and Shredder (Pocket Fritz 2) available for handhelds. Gromit plays usually solid and rather passive, but is the weakest of the four engines. On the other hand, SOS plays a very aggressive style, while Ruffian plays more ‘human’ and very positional chess. A drawback in PGM is the missing ELO handicapping, which makes it difficult to adjust the strength according to the players strength. Yet, the playing strength can be adjusted by changing hash size, pondering mode and time control. The estimated strength on a 400 Mhz device is approx. 2280 Elo for Gromit, 2540 Elo for Ruffian, 2430 Elo for SOS and 2600 for Fruit. A nice feature is the book control option that allows you to chose between different available opening books and you can set the book moves the program plays. As the only program, PGM offers also voice announcements of the moves on the board which have to be downloaded and are available for English, French, German, Spanish, and Dutch. One feature that is very good to have is the new training mode. A training database is included which can be enhanced on your own. PGM also includes several very good piece sets. For professional use, I recommend the maple board in combination with the piece-set ‘Cases’. In summary, this program is highly recommended. You will not be disappointed by it. It has more functions than any other chess program and is cheaper than it’s closest rivals Pocket Fritz 2 and Hiarcs. Here a 10 min Blitz game, ponder on against Fruit 2.1 which was somewhat disappointing for Fruit, despite it’s overall strength:

CE Board v2.1.589.1

A. Zanchetta

Pocket PC

 

Additional to it’s chess playing engines, CEBoard is an application made to enter and view chess games on a Pocket PC. It can be downloaded for free at http://www.zanchetta.net/CEBoard/ .It saves and loads files using the PGN standard which allows to review in software like Chessbase games entered on Pocket PC, and to review on a PPC games published on the Internet. It allows the entering of variations, comments and setup of positions. The best function in my opinion is the support of text annotation in PGN-files. Unfortunately, CEBoard does not have sound support and the design is not as good as it’s commercial competitors, but it is still good enough that you do not get a headache using it. CEBoard comes with currently three engines (more probably to come). The main chess engine is Crafty Classic 2004, developed by Michael Byrne which is a special version of Robert Hyatt's famous Crafty. It has many different personalities against which you can play such as Beginner, Novice, Expert, Anand, Botwinnik, Capablanca, Fischer, Kasparov, Lasker, Steinitz and many others. Additionally, the probably two strongest chess engines Fruit and Toga (based on Fruit) are downloadable (and another chess engine, Homer, will follow soon). Windows CE is not as powerful as Windows XP and does not include a task manager able to kill a process without user interface. Therefore, the engines are integrated into CEBoard's process as DLLs. For the Crafty engine, many opening books are available, however the cab-file does not include any opening books. You have to download them and then copy them into you device and change the registry (this part is explained at the homepage). Crafty Classic 2004 is the only Pocket PC engine that supports endgame-tablebases (entire 4 -man EGTB takes up only about 30 MB). In order to support endgame-tablebases, you have to specify their path in the Pocket PC's registry. For that, you have to use a tool such as PHM Registry Editor. Other valuable features are a logfile function and landscape mode, among others. Unfortunately, CEBoard has neither a Hint button, nor does it have a coach watching feature, which is standard in most other programs. Missing is also an help-file, which may be helpful in figuring out the many features of this program. A nice and unique function of CEBoard is it’s dynamic level adjustment, which adjusts it’s playing strength to the user. In general, CEBoard offers many different playing levels and time control options (incl. Fischer time control), although the time/move feature and predefined time controls are missing. The move entry can also be improved; sliding of the pieces is not supported. Overall, I think that it can be the best chess software for Pocket PC in the near future – and that for free. Therefore, I recommend to everybody to support this software by testing it. I’m sure the programmer Alain Zanchetta will acknowledge any feedback. From my experience, the programmer is very nice guy and he is active in several computer chess forums.
