Rybka is in second place:

In case you want to object because of SMP, I would argue that SMP is an advance
just like better search or better eval.  It is not the fault of SMK that Rybka
and Fruit can't do it yet.

I have not done any graphs, but I do agree that there may have been a bigger
spike than usual recently.  I interpret this as really smart people getting
interested in computer chess.  The same sort of thing has happened in the past.

I think that the startling improvements are due to smart people with good ideas
and enough drive to implement them.

It is still relative.  Fruit was a blast from a cannot.  Rybka was too, with a
little bigger warhead.  But Fabien may have a bigger warhead on the shelf.

Some of the others may also innovate.  The Ruffian author was very quiet for a
while and suddenly unleashed his creation.  There may be another phase of that.

I think that some of the most capable authors just don't put enough effort into
it to become overpowering.  For instance, the author of Gullydeckel is a very
good programmer and a very good chess player.  I think he could add 1000 Elo to
his program (literally) but he is too busy doing real work.  Simlarly, the
author of Amy is quite a brilliant person and could advance with big effort.
But again, I think that hobby time is lacking.

To write a great chess engine requires two things:
Great ability
Great effort

What we are seeing is those things in combination.

You also need to be a little crazy (since the time spent writing the chess
engine could be spent -- for instance -- making money or having some recreation
or whatever).

Wait, that's three things.

And did I mention an almost fanatical devotion to the pope?

It might be irrelevant, but it is also pretty incredible.  It was a hot
steam-roller right out of the box.  And in the short time span, he turned it
into a towering juggernaut.

It's not clear to me.  I think that the biggest jump ever was pre-deep blue to
deep blue.  Everything else has been a tiny blip by comparison.  But that's not
a fair comparison because they had a huge and talented team with a huge budget
and spent huge time and resources.  Nobody can compete with that.  Except maybe
Hydra.  Not sure about Hydra, though.  They have already spent a big pile,
that's clear.
