I've managed to play four games with my new 'toy'. All played on my Pocket iPAQ
v 1.5 GHz P4. Yes I realise that there is quite a difference in hardware so I
dug out my old chess programs. Three of the games were against Fritz 2 and one
against Sargon 5. Pocket Fritz managed two draws. If Stefan M-K is reading
this he might like to take a look at game four. Despite this being a *VERY*
boring game, in the final position Fritz 2 claims a draw by 3 move repetition
and Pocket Fritz is still showing +1.6 to white. Pocket Fritz also says it a
draw - so the question is - does Pocket Fritz's engine recognise a draw by three
move repetition?
Here are the games:
