Hello Folks, for those interested, here are the other two games that
Fischer played against the Greenblatt computer in 1977. In Both games
Fischer has black.

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nd4 Nf6 5.Nc3 a6 6.Be2 e5 7.Nb3 Be7 8.Be3
0-0 9.Qd3 Be6 10.0-0 Nbd7 11.Nd5 Rc8 12.Ne7 Qe7 13.f3 d5 14.Nd2 Qb4
15.Nb3 de4 16.Qd1 Nd5 17. Ba7 b6 18.c3 Qe7 19.fe4 Ne3 20.Qd3 Nf1 21.Qa6
Ne3 22.Bb6 Qg5 23.g3 Ra8 24.Ba7 h5 25.Qb7 h4 26.Kf2 hg3
27.hg3 f5 28.ef5 Rf5 29.Ke1 Raf8 30.Kd2 Nc4 31.Kc2 Qg6 32.Qe4 Nd6
33.Qc6 Rf2 34.Kd1 Bg4 35.Bf2 Qd3 36.Kc1 Be2 37.Nd2 Rf2 38.Qd7 Rf1
39.Nf1 Qd1# O-1

1.e4 c5 2.Nf3 g6 3.d4 Bg7 4.Nc3 cd4 5.Nd4 Nc6 6.Be3 Nf6 7.Nc6 bc6
8.e5 Ng8 9.f4 f6 10.ef6 Nf6 11.Bc4 d5 12.Be2 Rb8 13.b3 Ng4 14.Bd4 e5
15.fe5 0-0 16.Bg4 Qh4 17.g3 g4 18.Qg4 Bg4 19.Rf1 Rf1 20.Kf1 c5 21.Bf2
Be5 22.Be1 Rf8 23.Kg2 Rf3 24.h3 Rc3 25.Bc3 Bc3 26.Rf1 Bf5 27.Rf2 h5
28.Re2 Kf7 29.Re3 Bd4 30.Rf3 Ke6 31.c3 Be5 32.Re3 d4 33.cd4 cd4 34.Re1
d3 35.h4 d2 36.Rd1 Bc3 37.Kf2 Bg4 38.Rh1 Bd4 39.Kg2 Kd5 40.a3 Ke4
41.Rf1 Kd3 42.Kh2 Ke2 43.Kg2 Bh3 44.Kh3 Kf1 45.g4 d1=Q 46.Kh2 Qe2
47.Kh3 Qg2# 0-1

Playing through the above games, it is interesting to note the
Greenblatt computer's complete lack of positional savvy . In both
cases, the
computer gives away multiple tempo in the opening and gives up the
center without a fight leading to a steamrollering in both cases-also
note the classic trapped bishop in game 1 (17.Ba7 b6) leading in this
case to further disintegration of the position - I believe that Deep
Thought repeated a similar error against Kasparov.

As a side note, I would like to address the issue of 17.Kg7 in the game
Posted in the message "Fischer v MIT's Greenblatt Computer 1978"
(actually, the game was played in 1977). The move is not as unlogical
as it appears. The poor computer is trying to come up with a plan to
exit its King away from the lines of fire - it is immeadiately faced
with the move 18.Rf3 which wins the Queen because it has no avenue for
escape but more importantly will indirectly leave the Kings immeadiate
area even more vunerable to attack eg 18....Qg3 19.Qh7 mate. I would
offer instead of
17.Kg7 17.Rd6 which I think prolongs the agony a move or so longer.
The real problem with the game however is in the opening (once more)
with 4..... Bb4 leads to the loss of a pawn or the terrible g5 that the
computer plays in an attempt to save the doomed e pawn much better was
4......Nd5.

Ok... this might be interesting. In the middle 70's, Greenblatt
developed a special piece of hardware called 'cheops' that was (this
is a vague memory/description, sorry) simply a tactical search only.
His original program used this thing to prove that the move it liked
was either tactically ok or tactically bad. And _this_ machine was
very likely much stronger than the original 1400-1500 of machack from
the 60's...

However, this thing never competed anywhere in any open competition,
although I think that maybe David Levy played it two games around the
same time as the last match he played against chess 4.6, which I think
was also around 1977 or so.
