Can anyone explain how/why Fischer lost is bishop in the first game of his
match against Spassky in 1972?
The fact that a bishop capturing the h2 or a2 pawn and getting trapped after
g3 or b3 is trivial. Everyone knows that. Did he really think he had chances
after sacrificing the bishop for two (or three?) pawns?

Or was it just a mistake ?

Once I played a game with Beginner Level.

In 4 moves my Bishop was gone.

After that in next 2 Moves Beginner took my King. And I lost the game
to Beginner in just 6 Moves.

Beginner never does mistake. But it always plays with same
intelligence. Thats the advantage of Computers then never get tired
and they can play continiously.

Only Strong players like Help Bot and Skoop are able to beat the
Beginner Level as they play nice strategies to win the games.

The Soviet GM Igor Bondarevsky said:

"I think there are three reasons:
"1. The american doesn't like to play positions without counter-
chances, aiming only for a draw. He always tries to change the course
of events, to obtain play of his own.
"2. Fischer's intuitive grasp of position is not without flaws. On
this occation it failed to indicate to him that taking the pawn gives
White enormous winning chances ...
"3. Fischer apparently miscalculated in the variation with the final
move 35.Bd2!, and yet the calculation was fairly simple. Here is a
vivid example to smash the myth of him being a computer."

I'm not sure how valid Bondarevsky's comments are, but thought they
were worth presenting.

Anyone rated above 1100 can beat the pants off Beginner level again
and again and again!

In that particular position, it was far from
"trivial".

First of all, Black could advance his h-pawn
and exchange it (or possibly even promote it)
in an effort to free the Bishop.

Secondly, in order to finish the job, White
had to not only combat the h-pawn's advance,
but also he had to see that in all lines his
King and Bishop would work together to
cover all the various escape-routes.

Generally, speaking, Boris Spassky's move
(K-d3) is the sort of move which separates
the world champions from the also-rans. You
can find very similar things in the play of all
the world champions at their respective
peaks. In fact, the victim in this game, GM
Fischer, wrote about one in his MSMG book;
he noted that in some boring position, Tigran
Petrosian -- then world champion -- played
N(f3)-d1, heading for d3; the d3 square was
(just barely) closer to the center of the
board than f3, hence, a minute improvement
in the Knight's position was effected. Most
players would not even consider trying to
"improve" the positioning of such a piece,
which looked pretty darn good sitting on f3.

In addition to the two pawns, Black also
gained several(?) tempos with which to
centralize his King-- which was well back.

The error seems to have been a simple
miscalculation-- missing White's Bishop
retreat at the very end-- B-d2. This reminds
me of so many comments regarding world
champion Alekhine; it was noted that many
of his combinations had a "killer move" at
the tail end, which is ever so easy to
overlook. Instead of playing routinely as
in a famous Larry Evans quote ("Here, nine
out of ten grandmasters would have..."), the
world champion actually calculated what
would happen if Black were to grab to h-
pawn, and correctly concluded it would
give Black indigestion.

Since capturing the King is not legal in
chess, you really lost in just five moves--
the point where your King was *about* to
be captured on the next move.


That is, unless you could have escaped.

That claim is ridiculous. The program plays
reasonably well in the middle game, and only
*if* such a player somehow survived to the
endgame would he find himself at a significant
advantage.

Personally, I think I could beat a roomful of
USCF 1100 players in a simultaneous, while
taking the GetClub program too lightly has
sometimes resulted in draws or even a rare
loss, now and then. Although I would prefer
to have real players with real ratings to go by,
if I had to guess I would put the Beginner
level at somewhere nearer USCF 1500 than
USCF 1100-- maybe even higher, since the
glaring weakness in the endgame is quite
irrelevant unless a player is strong enough
to successfully exploit it.

Now here is the problem: there is no set
time limit on the human opponent at Get
Club, so a weak player can think as long
as he likes, and that means the program
is getting short shrift. I expect that if we
could equalize the thinking times, even
GetClub's Beginner level would rise to
a level closer to 2000 USCF, merely by
being a Pentium-class computer and not
a human.

There is also the problem that Fischer had caused all these problems -
postponements, the room, Kissinger, Slater - and the first game was
really really dull up to move 28. When he saw that there was ½ a
chance to make the game interesting he took it.

Spassky may have made a mistake himself with 36.a4, and Fischer may
have been able to draw with 37...a6.

Earlier, for white to win after 32...g5 33.Kg2 g4 34.Kxh2 h3 is not
easy.
