(English and German)
Chess Genius for Palm has a rating of ELO 1870 according to SSDF but this is related to operating system 4.1 .According to softwarehouse the programs performance is about 400 ELO higher when used with the new 5.0 operating system and faster ARM processors which is quite good for a handheld device.I wish SSDF or similar sources will regularly test not only PC programs but also those of Palm and similar devices to give detailed and updated information. Chess Genius is updated regularly and is free of charge for registered users. The program size is 163 kb
(unpacked),and recognizes all chess rules.PGN recognition is also available. The opening book consists of 9442 positions and recognizes transpositions in the move order thus remaining in the book irrespective of the move order played.
Chess Genius has a detailed menu which enables easy and efficient use.It consists of New Game determining color selection and in addition Mate in and Game in levels being adjusted according to a fixed time level for the function concerned.For Beginners there is an easy level also being divided into ten levels from the easiest to the hardest. Analyse Game and Player vs IR are also enabled.The program has altogether innumerable number of Levels with various playing , mate solving possibilities which can also be adjusted with this selection.Mate in and Game in within the selection also enable different thinking times.Color of the Board,Engine Preferences can also be adjusted with ease.The general preferences extension of the New Game branches to Permanent Brain (thinking process is on when opponent is thinking ) Tutorial and Sound on and off.The thinking process is visible in the analysed move order and a digital clock gives information regarding used thinking time/length in total and for the current move also informing when human has to move. The result of the analysed position is also reflected showing the evaluation with either a plus or a minus figure.

MIDDLE GAME :
The program plays very good chess in the middle game and is one of the two rated Palm OS compatible Chess Programs by SSDF.The program is a World Championship winning Program For Palm OS Platform.It is extremely fast and efficient in tactital positions. The setup below used to test before for other Palm OS programs on these pages was given to Chess Genius too.
White : Pawns on a4 , c5 and h6 , Rc4 and Ke1
Black : Pawns on a5 ,f3 , f7 ,g6 and h7,Be4 ,Nh8 and Kd5
The Key Move 1. RxB is already found at 5 seconds thinking time for each move . At 2 and 3 Seconds level the correct move is found however the continuation 1..KxR can not avoid the Queening of the Pawn on c4 escapes easily after 2.c5 The game is lost for Black also when Kxc4
is played but 1...KxR loses faster. Click here to add your text.
THE ENDGAME ;
For the endgame we have two different positions.One is a formerly tested setup with other programs which has the following setup ;
White : Pawns on f5, g5 ,h5 , Ka1t
Black : Pawns on f7 , g7, h7 , Kc1
At one second per move level the Chess Genius finds the correct solution but not the correct continuation.At 2 Seconds per move level the program Finds the correct move and the solution by getting a passed pawn and winning the game.
The second setup is to check the ability of the program when Pawn Promotion is in question the setup is as follows:
White : Pawns on h6 and f7 , Knights on e7 and g6 and King on g5
Black ; King on h7
White to move plays 1.f8 + Promotes to a Knight and checkmates immediately at Mate in 1 Level and as of Easy Level 3 .The program plays the move instantly .None of the reviewed PALM OS programs till now could checkmate in such a position as pawn promotion could result in a Queen only which will mean a stalemate in this position.
In the endgame the program can make the following elemantary mates :.
King + Queen vs King
King + Rook vs King
King + Bishop + Bishop vs King
The review of Pocket Chess Deluxe is now ready:
The only program so far mating with :
King + Bishop + Knight vs King

The program announces mate giving the number of moves. I experienced several times mate in five and then number of moves diminishing until final position of checkmate is reached. The program is fast therefore even at very low levels King + Bishop + Knight vs King mates are successfully achieved.ur text.
