<>I meant it more like "computers can be beaten", there are not invincible. For example, >you beating Vortex :)

Well 2 things:
I'm not beating Vortex since i only beat it with white and i lose with black, so we are somewhat even.
And Vortex has a long way to travel at the magic world of Gothic Chess, to be able to reach the level that Chess-engines are today. I could grab some wins from Fritz 1.0 and early versions of Chess Genius, but with todays development and hardware it's almost impossible. I can't win with any way Deep Fritz 8 at quad! The same i suppose will be with G.Vortex. At 8-9 years i wonder if i could still have any wins.


Speaking about your game with Deep Thought at 1989, we should note the following things:

7...Bxf3 was a bad move from D.Thought.
All todays commercial top engines(Shredder 8/7.04/7/6, Deep Fritz 8/7, Fritz 8/7, Hiarcs 9/8, Junior 8/7, Chess-Tiger 15/14, Chessmaster 10000/9000/8000, Gandalf 5, Ruffian 2.1.0/2.0.2) as also ALL free today engines suggest 7.Bxf3 as a bad move IMMEDIATELY and play 7...Nf6 instead.
Shredder 8 for example gives 7...Nf6 a +0.14 only for white while 7...Bxf3 a +1.03.

8...Qxd4 was an awful move according to all todays programs. And they realise it IMMEDIATELY. Shredder 8 for example gives 7...Qxd4 a +1.78 for white in 30 seconds and after 2 minutes a +2.09, while 7...Nf6 a +0.91. A huge difference for those who know. And while 7...Nf6 is almost steady as plies increase, the 7...Qxd4 has a big fail low. Deep Fritz 8 has a little problem on this as it does 19 seconds to realise it's a bad move. Very soon (50 seconds) it sees that it loses.

All this on a poor PIV 1500 MHz. When we speak about 3.2GHz or quads then it's a matter of seconds to see the truth.

These things show that the days that computers was material hunters, belong to the past. Sometimes even todays computers show from where they've come from and play for material but this is happening very seldom.
