Or the king has a flight field. And it is precisely this what wanted to show My intention was not to embarase you. But to show what happens so often in practice. (For this reason I made so manny mistakes on purpose before i posted the main mesage.) because so many factors can change the position Also helpfull if you want to make such positions yourself. For tutorial purpuse. Regards Marc
