Go, in my opinion and the opinion of many others is the most complecated, followed by chess. Othello, on the other hand depends on the roll of the dice which includes 'chance' and there for should not be compare to the others. There are both Othello and Checkers programs that have defeated the worlds champions many different times, so I would conclude that they have been solved. Chess on the other hand with the way the programmers are working today might not really be solved, but for all pratical purposes will be using the technics that are in vogue today, ie. unlimited opening books, unlimited end game books, might be consider to be solved in just a few more years. I still recall a tournement held in 2000 where one program defeated another without ever leaving its opening book. I do not consider that a chess thinking machine or program, just a look-up program that could not solve the problem without is extensive books. Many people have argued about this topic for years now but I have to ask "what is considered an opening play, the first 5, 10, or 15 moves", "Where does mid-game start", and "when does end game play start"? Table bases for the end games where there are only 5 or less pieces left on the board sounds reasonable, but I think that if anyone ever programs to find the best endgame without table bases then it will be a better program. I would like to see a world wide tournement held which limits the pre programmed openings to say 10 moves, period and then let the programs proceed based upon their own 'real' strenght. The people who oppose my operating theory the most at this time are the ones who have already incorporated the above mentioned ideas into their programs. Only time will tell if and when the games are really solved depending upon what king of programming is allowed. Bill
