{This game is perhaps the most brilliant on record that refutes the beginner's
scale notion holds that two rooks ( " 5 + 5 = 10 points " ) vs a queen ( "
only 9 points " ) is an advantage for the rooks. Fischer's calm sacrifice of
both of his rooks created shock waves all over the world when this game was
played. A number of Soviet Grandmasters at the time claimed that Fischer had
been "lucky". It is startling to see Lajos Portisch, who was one of the top 10
players in the world for more than 12 years, make this decision and then go
down to such a decisive defeat as a result of it...} 1. d4 Nf6 2. c4 e6 3. Nc3

{This is without doubt, the most COSTLY game ever lost as a result of
mis-valuing the basic worth of the chess pieces. It is fair to say that
Bronstein's mis-evaluation here cost him the World Championship. The
beginner's scale of material values would turn out to be very costly baggage
indeed to David Bronstein; he was never again able to mount a successful
challenge for the world championship after this narrow miss...} 1. d4 Nf6 2. c4

Ke2 Kf7 {Beginning with a straightforward swap of a pair of knights, Black can
gradually carry out the following solid defensive plan: move his king over to
d7, oppose bishops at d6, then offer further swaps of rooks on the "c" file.
Against this careful plan, it is difficult to imagine the game drifting into
anything other than a routine draw-leaving Bronstein 1 game up going into the
last game of the World Championship. Notice that Bronstein's plan envisions
winning Botvinnik's pawn at b3. It does so however at the cost of two bishops
for two KNIGHTS. This is sometimes referred to as winning the advantage of the
"double bishop -pair". The two bishops FULLY balance two knights plus a pawn.
( 6.35 vs. 6.20 using the Advanced Material Scale ). Also, from a purely
positional standpoint here, the winning of Botvinnik's pawn was foolish, since
Bronstein's "extra" pawn on the QW was doubled and virtually worthless.
Botvinnik proved that this drawable endgame is if anything, more difficult for
the side with the two knights and pawn rather than the side with the two
bishops.}) 32. Rxc8 Rxc8 33. Rc1 Rxc1 34. Nxc1 Ba3 $5 35. Kd1 Bxc1 36. Kxc1
