I changed #wpr and #bpr to var wpr and var bpr, because these values might be changed by a preset that uses the chess include file. As a general rule, you should use the var operator to get the value of a variable in an expression, because using # plugs the current value directly into the expression, but a function may be used multiple times when a variable has different values.
