I guess option 1 is better. My 'old' SEE would 'work' on this position as it does a normal search linited to capturing on one sqaure i.e. goes with option 1. My current SEE does not work as it does not see the difference between R7xB and R1xB. I suspect that many SEE routines would not work with this - Leen's routine which I based mine on wouldn't. I'm not sure if it's worth worrying about as it's so rare - I guess a simpler and faster routine would work in 99.9% of cases. Regards, Steve
