While I am more interested in the tcp/ip play then pbem, it should have some "anti-cheating" enabled. Since I do not know how combat/movement is resolved in the game I will take some liberties.It's done by not showing the player's whose current turn it is the outcome of combats and movements. This would probably not be feasible with tactical level games because of all the minutae involved during a player's turn, but it could work with strategic or maybe operational level games. I'm thinking of Gary Grigsby's War in Russia, for example. In this game, all movements and combats are plotted and then executed. The player watches the execution as his movements and attacks unfold, but it really would not be necessary for him to see this, since he can't change anything at that point. Instead, the game would show a replay during the player's next turn. I'm aware that in War in Russia, players also plot and execute air attacks prior to land combat, but the results of those too could be hidden until the following turn.Also consider if combat was resolved on your opponents turn. Thus, you never even saw the enemy forces till your next turn.
All this depends of course on how the game executes its phases etc.. I myself like simultanous turns that allow both players to watch the execution phase at the same time with bonuses for faster players but thats just me.
