I've browsed around trying to prove your statement, I can't find anything
anywhere to back it up.

Some rating lists indicate Crafty is 50-100 points stronger, others show they
are on par, no list anywhere I could find says SOS is a Crafty killer.

I think SOS is a very strong engine, my impression is though that Crafty still
holds an edge.

Of course at home everybody kills Crafty completely, heck at home everybody
kills Junior and Shredder too :)

>You need a bugfree engine to kill crafty, that's all.

It would be stating the obvious to say "that's not all you need".

But anyway, if you know what it takes to kill Crafty, why don't you build an
engine that can do it?

And if you believe you already have an engine that can do it, why not make some
attempt at convincing the rest of us?

>SOS is bugfree.

Not sure, IIRC it had some funky mate scores on a position I tried,
probably has been fixed now but is bugfree only until the next crash :)
