1.e4
{B00 King's Pawn Opening. The King's Pawn opening move is both popular and logical. It controls the center, opens lines
for both the Queen and the Bishop, and usually leads to an open game in which tactics, rather than slow maneuvering,
predominates.}
1...Nc6
{B00 Nimzowitsch Defense. The Nimzovitch Defense to the King's Pawn is an attempt to steer the game into obscure lines
without giving White any clear targets.}
2.Nf3
{B00 Nimzowitsch Defense / Declined. The development of the King's Knight invites transposition into the Ruy Lopez,
whereas the tempting 2.d4 allows Black the complicated reaction 2...e5, when Black is playing a sort of Alekhine's Defense on
the Queenside.}
2...e5
{C44 Queen's Knight Variation (transposed).}
3.Nc3
{C46 Three Knights Opening.}
3...Nf6
{C46 Four Knights Opening. With Black's final Knight development, the Four Knights Game results:  Several imitations of
moves until Black must diverge and be content with a sound, but uninteresting game.}
4.d3
{C46 Four Knights Opening.}
4...g6
{Out of Opening Book. Bb4 would have been in the Four Knights Opening book opening. Slightly better is
d5.

{Leads to 7.dxe5 Nxe5 8.Nxe5 h6 9.Bd2 Qe7 10.Nf3 Bxc3 11.Bxc3 Nxe4 12.Be5 Qc5, which wins a knight and two
pawns for a bishop, a knight, and a pawn. Better is h6, leading to 7.Be3 exd4 8.Nxd4 Bb4 9.Nxc6 Bxc3+ 10.bxc3 dxc6 11.Bd3, which
wins two knights and a pawn for a bishop, a knight, and a pawn.}
7.dxe5
{Threatens Black's knight at f6.}
7...Ba3
{Look out. Hangs the bishop at a3 and frees White's knight at c3 from the pin. Leads to 8.bxa3 Nxe5 9.Nd5 Neg4 10.Qd4
d6 11.Bxf6 Qd7 12.h3 c5 13.Qd2, which wins a pawn for a bishop and a knight. Much better is Nxe5, leading to 8.Nxe5 h6 9.Bd2 Qe7
10.Nf3 Bxc3 11.Bxc3 Nxe4 12.Be5 Qc5, which wins a knight and two pawns for a bishop and a knight. This was black's key error.
Black was not able to regain the last ground and was eventually
mated.

9...Bxb2
{Forks White's knight at c3 and White's rook at a1 and isolates White's pawn at a2 and White's pawn at c2. White wins
a queen, a knight, and a pawn for a pawn. White is ahead by a queen and a knight in material.}
