I am trying to write the game code for 2 new pieces I want for my newest chess variants. The first, a bent rider, called the lion should move like a bishop for 2 squares and then towards outside like a rook. It may also move like a dabbabah. I have written the code bellow that has the problem that allows the final rook moves without checking for the first bishop part of the move. Please take a look:

def Lyon

fn (checkride #0 #1 1 0 and empty #0)

where #0 2 sign - file #1 file #0 2 sign - rank #1 rank #0 #1

and not fn Knight #0 #1

or and checkride #0 #1 1 1 <= distance #0 #1 2

or fn Dabbabah #0 #1;

The second, it is also a bent rider, called the tiger should move like a rook for 3 squares and then towards outside like a bishop. It may also move like an alfil. In the same way as before the bishop moves are allowed by my code whitout checking the rook ride. Code so far:

def Tiger

fn (checkride #0 #1 1 1 and empty #0)

where #0 0 * 3 sign - rank #1 rank #0 #1

or fn (checkride #0 #1 1 1 and empty #0)

where #0 * 3 sign - file #1 file #0 0 #1

and not fn Knight #0 #1

or and checkride #0 #1 1 0 <= distance #0 #1 3

or fn Elephant #0 #1;

I could not find code that block the ride in the first part.
