# Battle of Castles

Logic Level 4

What is white's strongest move in this position?

Details and Assumptions

White pawns are moving upwards (the bottom left square is a1). Take $$(1,1)$$ to be the bottom left square (so $$(8,8)$$ is the top right).

Assign the following values:

• King = 10
• Queen = 9
• Rook = 5
• Bishop = 4
• Knight = 3
• Pawn = 1

Submit your answer as $$v \times x \times y \times P$$ where $$v$$ is the value (as defined above) of the piece which is moved, $$(x,y)$$ is the square the piece is moved onto, and $$P$$ is the value of the piece the pawn is promoted to, should the move be a pawn promotion. If the move is not a promotion, let $$P = 1$$.
