On the way to work today i came up with the idea for a "Tafl Chess" variant - basically the pieces have the same moves as in regular chess but capture is by flanking (like in Tablut) rather than substitution as in normal chess. I played a game out when I got home and it seems to work - any thoughts?

Haven't checked to see if this has been discussed before (apologies if so), but has anyone ever encountered Arimaa before? I just found it on Wikipedia (http://en.wikipedia.org/wiki/Arimaa if you want to take a look). Interesting looking game - now I just have to find a way to play it!
