for many years thsi "switch" move has been a thorwn in my side. But it has won me many games! I have accepted it as a part of the game. there is a site which plays this game only www.deepmachines.com/bigbattle where you never knwo the value of a piece every thing is done blindly. And believe me it definietly is flawed. I think that the reason they do thsi is to prevent pieces from being suicided and to proect your army more. In real war that would be considered savage. but i think that were gettgin off the subject. In my note taking i wouyld track both pieces for the rest of the game such as A1 and B2 and follow them around and maybe throw a 5 in front of it and i kknow that my ?5? is safe b/c it was a +3.
