But that is an equally interesting alternative question. I think that the second example that I compose is better [D]1Q5B/2N1Q1R1/4N3/Q1B1k3/3RBR2/8/7Q/Q3Q1K1 w - - 0 1 I can modify movei to calculate how many mates in 1 white has in a short time but it seems that every move of the pieces except the kings and the queens is indirect mate because every square near the king is protected by at least 2 white pieces and only one can stop defending it. I am sure that there is a better example than it. Uri
