For those who may still belabor in thinking that computer games are boring to
watch, allow me to share a few entertaining games played by Rybka and Hiarcs 10
(hypermodern) using the suite I designed. I highlighted a few positions,
including one worthy test position. The games were played on an Athlon64 3500+
at 5mins + 2 sec increment.
Just so that I am not accused of bias in Rybka's favor (chess is my first love,
not an engine BTW), the first one I was tickled by was won by Hiarcs:
It came from the Benoni, and Rybka played 17...g5 with the idea of 18.Bg3 Nh5:
[D]r3r1k1/pp1b1pb1/1q1p1n1p/2pP2p1/1nB1PB2/2N2N2/PP1Q1PPP/R3R1K1 w - - 0 18
but Hiarcs took a dose of tiger juice and played 18.e5!
In the following game, resulting from the Scandinavian defense,

1-0
the game seemed to proceed normally, though Rybka managed to get the white
pieces to play very actively, when Hiarcs stumbled with 27...Ng6?:
[D]r2r2k1/pQ3pp1/2pBp1n1/6R1/3P3P/8/2q2PP1/4R1K1 w - - 0 28
Rybka played 28.h5! and Hiarcs countered with 28...Qd2 attacking both rooks:
[D]r2r2k1/pQ3pp1/2pBp1n1/6RP/3P4/8/3q1PP1/4R1K1 w - - 0 29
and Rybka uncorked the really spectacular 29.hxg6!!

The last game was one that would have made Nimzowitsch proud and that led to
some very aesthetic positions:

Rybka played a great game, with some very interesting play in the opening, and
illustrating how to blockade pawns with pieces in rare fashion. This led to the
following geometrical motif:
[D]2r1rbk1/pp3q1p/5p2/4pN2/3pR3/3N3P/1PPB2P1/3Q2K1 w - - 0 29
I really like the diagonal lineup of the black pieces on the black squares and
the white on the white. This continued though, and a few moves later they
reached this position:
[D]2r1rb1k/p6p/5p2/1p1qpN2/4R3/2BN1Q1P/1P4P1/6K1 w - - 0 33
Another attractive motif, though this time with a small tactical touch with
33.Nf4! Qf7 34.Nh5 and white has a huge initiative. After 34...Re6 35.Rg4 a6
36.Qd5 Rce8,
[D]4rb1k/5q1p/p3rp2/1p1QpN1N/6R1/2B4P/1P4P1/6K1 w - - 0 37
Rybka played 37.Nhg7! winning material and eventually the game.
