tt= 20 means 1 MEGABYTE of hashtables, Mr. Theron.

How come, you know or think to know, what Midscape thinks ? Name it your
personal suggestion, that looks far better !
Besides, whichever customer asks about changing of the settings, wilöl get a
concrete answer, BTW - it's fairly known in common, anyway.

What do you insist the comrade to do ? Send SSDF testers a description how to
change the tt in a prog ?

Who's doin' what up there ? I think the majority has a well settleld overall
education concerning the useage of chess progs. So if they don't need soemthing
-it's advice of this kind.

Concerning the overall quality of the engine, which you obviously doubt, I
presume it was way before you entered this scene - when de Konings engine led
the SSDF list with an ELO of 2.402. His board computer - with a relatively poor
hardware - comparing to todays needs (!) is still ranked No 31 - about one
quality level with Jun. 4 on 90 MHZ - and this was an - old - engine.

I, of course, can never foresee what the prog would achieve, if participating,
at all - but I predict around rank 6-10; which I consider as brilliant enough.

What I'd else like to know :
Who is " we " ....are not blind enough to.... ?
You speak for several people, do you ?
