I think the opposite is true. Let's first list entries which are possible dual: Crafty Diep Ferret Fritz Junior Shredder SOS Possible entering single title: Gandalf Gromitchess Pharaon Rebel Spidergirl Tao Tiger Xinix Now even if none of the single cpu machines say they want to qualify for the multiprocessor title, then still there is a clear strength difference in favour of duals. Chance that a single cpu machine is going to win this champ is real small. The only possibility of this happening is if Shredder enters the single cpu competition. Even then it will have a problem with 9 rounds to go. When we closely examine the single cpu list then we see a lot of strong programs (only strong programs in world champ usually), one of them, Rebel, could better next year ask to play for a senior title, as now it's not going to win any title, but it might of course help tiger by beating other single cpu stuff. This help must NOT be underestimated. Also with some major bookluck it might win itself that single cpu title. Anyway times will be tough to let a single cpu win the tournament. I estimate it at near 0% actually. And i'll explain why i think that's so low. First of all the only real interesting program to get a high score in the single cpu list would be tiger. This is the only program in that list which is equipped with a real killerbook. May i however remind that Tiger has major problems winning at levels like 2 minutes a move and that its antipositional play which is dominated by big search depths, is completely non-relevant as the other side of the board has 2 processors? So the extra search depth which Tiger gets by smart pruning and throwing away positional more correct scored variations, the other side of the board is compensating by another processor. So the engine tiger is joining a kind of nightmare championship for it. apart from that i think that also within the single list there are a load of engines which are better as tiger, if Noomen doesn't kill those in opening completely, then Tiger has a major problem scoring a full point. And as we know, to win a tournament like this, you need like 7.5 points, which is means you can only afford 3 draws and 6 wins. In short each 3 games you may at most give away half a point. One misevaluation of a position and misstrategy and you're gone. The practical chances that a single is going to get more points than a dual this championship i therefore see very realistically at near zero. In the case a dual is going to win this tournament, then it's very realistic to assume that all what counts in the score tables that this program is ahead in points of the other one with a world title. In human chess we have also 2 world champions. We have Kramnik holding the world title which he won from Kasparov by superb technique in the endgame. We have Anand holding a knockout-FIDE world title against a bunch of 2600-2700 rated players. both are great champs, but everyone will agree that the title of Kramnik is definitely more impressive. In this championship the dual title is therefore going to be more important, because the chance is over 99% that this is based upon more points than the single world title.
