Naum is the draw master and even Rybka has trouble stopping it!

So what? You seem to be nit picking, so let me do that as well. Zappa is another draw monster. Also you missed the ones below.

That concludes my 40/400 games, there will be no more.

It's also worth noting that Rybka is one of the engines that scales the worst with more processors, so in effect, the more processors both it and its opponent have, the more the opponent catches up. I'd bet that with a single engine at the same time control the result would be quite different.
