45?
least number of moves
Well, there have to be AT LEAST 30 moves (1 move to capture a piece). Also, you can't capture any pieces on move 1, so that brings the minimum up to 31. I also doubt there is a way to capture a piece EVERY move after the first, so I will take a guess and say 35.
obviously, as there are 30 pieces that need to be eliminated, it is impossible to do it in less than 15 moves, 16 since no captures are possible on the first move.
how can this be reached in the least no. of moves?
i'll give the moves if i get some comments
