I certainly believe there is a computational level at which pure tactical play
will defeat positional play nearly all the time, if not all the time. I think we
will see this phenonomen happen as an incidental occurance, due to ongoing
hardware improvements over the coming years. When this happens, I won't commit
to saying, partly because I don't really feel that any programmers feel the need
to experiment seriously in this direction anymore. However, tactical
improvements are going to come more and more slowly as time goes by, because
processor speed improvements would have to be highly exponential to allow
tactics to improve at the same rate as they have been thus far. So far, we seem
to be doubling processor speeds every year (keeping Moore happy), but this won't
be enough to keep the tactical improvements coming at the same rate. You only
have to look at the ELO improvement of programs such as Deep Fritz to see only
around 60 points improvement by going from a mere K6-2 450Mhz processor to a
modern 1200 Mhz Althon. (And arguably, a signficant component of the 60 points
could be attributable to the larger memeory available for hash tables). 18 years
ago, you would have got 100 points ELO by throwing out your 2 Mhz 6502 machine,
and purcahsing a 4Mhz 6502 machine!!! So doubling processor speeds a couple of
decades ago brought much greater improvements than even a tripling does today. I
predict that from ten years time, a ten fold increase in processing power will
only get you around 10 - 20 points ELO improvement, all other things being
equal.

I still think the key to defeating super Grand Masters on a regular basis
requires more hueristics, more knowledge and massive amounts of extremely high
speed and stable memory. I don't really think adding 200 or even 300 points to a
program's tactical ability will really improve it's playing strength against a
2700+ human, although it would certainly be much more noticeable in computer vs
computer competition.

And in closing, I would point out to programmers that , imo, the most boring
chess programs on the planet are the ones that emphasise tactics. I'd much
rather play against a program that searches very few nodes (and does a lot of
processing with each one), than one that goes hell for leather through as many
iterations as the hardware will conceivably allow, with little regard to
anything other than "he goes there...I go here....he goes there...I go
here....he goes there....I go here" ad infinitum.
