DEEP BLUE VS. KASPAROV

The Deep Blue vs. Kasparov match, (May, 3 to 11, 1997), won by machine, wokeup discussions about chess future.

People prophesies that machine speed soon will overtake any human opponent.

Let's see: A medium chess game can take 40 moves, each one having 35 changes both sides.

It means 3.35x10^123 possible moves (35^80).

The computer should be 4.66x10^119 moves per second fast (3.35x10^123÷7,200), instead of current 200 millions, in order to solve the game within 2 hours (official time). That is, 466 followed by 117 zeros!

When will machine reach this speed? People say that computers speed will continue to double each 13 months, as it happens nowadays. So, considering that 466 followed by 117 zeros is the same as 200,000,000x2^370 and that 370x13÷12=400, we can say the computers won't reach this speed before next 400 years!

Many people would say that reaching such speed every match played by two machines will result an inexorable draw. I don't think so. I think the white pieces always will win! Just like happens with people who start the Fifteen Matchsticks Game! Since it'll be definitively disclosed the secret of winning initial moves!

Of course I'm talking about a computer that plays just under its algorithm, without run to libraries (as the humans don't run). Its 200 millions speed doesn't solve even 4 moves both sides within 3 minutes (medium time per move on official games); this would demand more than 12.5 billions speed! (35^8÷180).

I still bet on human been!

KASPAROV AGAINST THE WORLD

It's easy to see that Kasparov will force "the World" to resign this chess game, before 30 moves, because most voters is made of mediocre chessplayers. Any medium player can do the same. Of course Kasparov knows he's doing no exceptional thing, but only promoting the sport, reason for have all chessplayers support, indeed. (Jul 7 1999)

FRITZ VS. KASPAROV - A FARCE?

The Fritz vs. Kasparov match, (November, 11 to 18, 2003), drawn, disappoints me about participants' honesty. High suspicious game two Kasparov 32...Rg7?? move (losing king's pawn and the game) and high suspicious game three Fritz 14...Bd6?? move (silly attempt to capture white queen) make me believe in a farce. Nobody convinces me Kasparov didn't make a deliberated mistake, in the first case, and we didn't have an human move, in the second case; powerful computers wouldn't commit such malicious and childish move:

Game 2 - Next move 32...Rg7??
Game 3 - Next move 14...Bd6??

I don't beat neither on Kasparov, no longer, nor on these half-machines-half-humans computers. I don't forget Kasparov himself accused IBM of fraud, on previous match (Deep Blue vs. Kasparov), as long as a lot of columnists accused Kasparov himself of suspicious behaviour. That's the question: Were we watching chess tournaments or "Deep Blue" and "Fritz" manufacturers' deceitful advertising?
