As for other potential competition:

Junior wet his pants and hid behind mommy's skirts. [Note 2]

Fritz screamed like a little girl and ran away. [Note 2]

Zappa (Zap! Chess) sat in his retirement home, marveling
at how good these nefangled whippersnappers are. [Note 3}

Hydra 64CL sat in the garage as his R&D team feverishly
tried to make him work. Previous Hydra versions slept
in, knowing that they couldn't beat the latest Rybka.
Look for an interesting matchup whenever Hydra 64CL is
completed. [Note 4]

NOTES:

Note 1: Rybka had a winning tablebase position but
did not have KRPknp tablebase installed.

If Zappa was sat in its retirement home, then which program of the same
name drew with Rybka in round 3 and came 2nd overall?

Although Rybka is clearly the best program there is at this time, and
fully deserves to win the WCCC at last as it is proven no.1 on all
rating lists and in other major tournaments, I think Zappa did well to
make 2nd in view of the fact that programmer Anthony Cozzie hasn't done
any work on it for (presumably) some 5 or 6 months.
