Fortunately, no downloads of Logistello are available, sparing me the humiliation of a crushing defeat ;-)

The real irony, is that I wrote an Othello-playing proggie on the Archimedes back at school which, IIRC, on its hardest setting could beat me >50% of the time. At which point it would be back to playing Son of the Return of the Revenge of the Attack of the Mutant Killer Polo Mints From Hell (title from memory).

That's pretty impressive, in a slightly different way to the one I had expected. What was the program logic? Just looking through all the possible alternatives at each stage, to the 1st/2nd/3rd/nth degree and applying some sort of evaluation function to 'em?

Given that you can beat a Nokia 7110, you can't be a bad player - so to program something which could beat you is rather good going!

It was fairly straightforward - look for the move that gives you the best score, to a depth of 1 or 2 moves (and assuming that the opponent makes their best move by the same rules), plus some weightings for certain squares - edges are good, corners are better and moves that would allow your opponent to gain a corner/edge are bad.

The 7110 isn't particularly strong - with very little coaxing, it would leave corners open at an early stage, allowing me to fairly easily build up large unassailable blocks.
