Human vs computer stonewall.

Post by jshriver »

Several years ago when I firsted joined CCC there was a player who frequented this place who was good at beating various computer engines.

He often used a stonewall (hope I have that term correct). Anyone know his name, handle, or where some of those are now adays? Think the last time I saw him or his games was when fruit first game out.

Thanks,
-Josh

Pablo was not beating various computers but only moved back and forth to wait for the moment when computers run out of time in all these blitz games at very short time controls.

Still interesting, and a win on time control is still a win. So it still shows a possible weakness. Wanted to study his methods. Anyone have a pgn collection from him?

Probably talking about Tim on ICC? I think his last name is Mirabel but I am not certain about the spelling. There were others that tried this approach as well and had a lot of success....

if you search this forum for his posts probably every 10th or so contains one of his anti-computer games:

Maybe a little outdated, but worth a look.
