I asked Fritz. He told me 1. e4 leads to a mate in 6543 moves >while all others draw! Can you post the main line of Fritz? mate in 6543 is a draw by the 50 move rule because there are 96 possible pawns moves and 30 possible captures. There are at most 126 moves that are captures or pawn moves and there are less than it because some pawns pushes are captures or some pawns are captured before they go to the 8th rank(1st rank). Even if you assume that there are 126 captures or pawn moves then it is impossible to put them in 6543 moves(every move is 2 plies except the last move) without getting a draw by the 50 move rules.
