Now that is a long time. You would be pretty fed up if you accidentally timed out after about 40 yrs.
I think 1550
30 pieces each removed @ the 50th move = 1500
+ 50 moves when only the kings are left
RE: the pawns promotions- it dont matter if they promote or not, the piece must go on the 50th move
The answer is 5,870.5
Did you take into account what happens after all the pawns are promoted, say to 4N's on each side and 4B's, where the B's of the same side all travel on the same color and the B's of opposite sides travel on opposite colors?
I didn't do it.
