BTW: had two more very early repetition draws. In different positions but with Mastersoft as black and as white in a Russian system against the Grunfeld.

Good points, easy to fire up and bang a game out with. X seconds a move is ideal as I use it at airports, on planes or hotel bars travelling on business. Good quality and no crashes or hangs.

Weaknesses.
It can get it spectacularly wrong. I have a miniture where it could have resigned on move 19 but I did not mate it until move 26 as it insisted on giving all its pieces away to delay mate. I also muffed a winning position and adopted a desperation tactic which included sacking rook to stop a pawn, leaving me with two connected passed pawns on the 5th (not 6th) with my king nearer, this it failed solve and I got away with it.

Tendancy for early draws by repetition. One as early as move 11, i had no choice and proved this later by replaying and making the only move open to me, which as I had judged resulted in my position collapsing. Another on move 17 should have continued with black playing Nc6 (afterwards I found 130 games in my DB with Nc6) but it just repeated (admittedly a GM and IM who obviously wanted to get to the bar early agreed a draw is this position back in 1996). Most of my games however last the typical 40 to 60 moves and I have had one marathon win in 95 moves. It is not a shock or failing that it is not as strong as my Deep Rybika running on a quad core, it seems to be evenly matched against Glaurung (except my 3gs has 50% more processor speed and 100% more ram than my wifes 3g) it is stronger over several games than the 2120 rated dedicated tabletop computer I have.

Weird opening book, rarely plays the mainstream and bread and butter openings one needs in tournament or team matches, especially as white. One rarely, if ever, gets into meaty lines of the sicilian or kings indian etc whether white or black. Plays g3, b3, f5 or nc3 way way way too often. Has a disproportionate tendency to play the Benoni against d4.

Style of play is like that of a social player, in terms of openings and tends to throw out ugly pawn moves infront of its king, it loves throw g5 infront of a castled king or even uncastled king.

I acquired the program as I am planning a return to competitive play after a 15 year lay off (I peaked at 2000 even longer ago) targeting my first tournament at Easter 2010 and wanted to practise whilst travelling on business or fishing. I use Chess Assistant and Deep Rybika which I also acquired at the same time or my dedicated table top Mephisto Master Chess, recently extracted from the loft and dusted off, at home. Due to the weird opening book it is really not suited to tournament prep and hence does not meet my objectives, I will be replacing it on my Iphone 3GS with something more appropriate to what I want, either Glaurung which my wife has on her 3g or HIARCS 12.1.

It is great for just banging a game out anywhere and for some will be the perfect travelling partner. Seems tuned to social players and plays like a very very strong one,(or it thinks it is Bent Larson(grin)) but social players do not need the 30 and 60 second levels. I have not tried anything lower than 30 seconds personally.
