Nxd4 is a complex one with various possibilities for both sides. This is the most common recapture and sets one more trap. Be7 is a blunder and should be substituted with Ngf6, when the minefield of traps has been safely crossed. White primarily intends to castle (O-O), aiming to play Re1 or Nc3. This strategy is designed to counter Black's potential moves, such as Nb6, Ngf6, and Ne5. However, if Black plays Ngf6, creating a threat of Ne5, White is forced to castle, allowing Black to proceed with g6. Square c6 is a point of contention. The white knight on d4 guards it, while the black pawn on b7 also guards the same square. The white bishop on b3 can capture the black pawn on f7, but the black king on e8 supports this pawn. White utilizes both the c1-h6 and a2-g8 diagonals. Meanwhile, Black uses the d8-h4 and c8-h3 diagonals. The black bishop on f8 supports the pawn on g7 and protects the king by guarding g7. The black pawn on d6 guards the square e5, and the pawn on c7 protects the king by guarding c6. White has several options for the bishop, including Bb3, Be2, and Bd3. White can also play c4. Black, on the other hand, can consider moves like Ne5, c6, and h6. The black pawn on b7 also protects the king by guarding c6. The black knight on g8 can move to f6 to either capture the unsupported white pawn on e4 or guard the square d5. The white knight on d4 can move to f3 to guard the square e5. The black bishop on c8 can move to g4, threatening the white queen on d1. Theory table 1. e4 e5 2. Nf3 d6 3. d4 Nd7 4. Bc4 exd4 5. Nxd4 5 6 7 8 9 10Hanham Variation...Be7?
