Here are the EPD records for the two possibilites: 8/8/8/8/8/4k1B1/4r3/3K4 w - - acd 4; acn 485; acs 22; ce -305; pv Bb8 Kd3 Bc7 Ra2; 8/8/8/8/8/4k1B1/4r3/3K4 b - - acd 45; acn 544; acs 1; ce 32722; pv Kd3; I'm anything but an expert, but I will hazard a guess as to what is meant. It must mean that white is on move, because if it is black's turn it is a sure checkmate. Black has mating material, so if white can force a 3-fold repetition because of the current arrangement of pieces, or avoid capture 50 moves, it's a draw. If the pieces were situated in a bad way, there would be no way to force the draw. Here is a draw (provided white does not do the absurd Ke1): 8/8/8/8/3n4/4k1B1/4b3/N2K4 w - - Is it a positional draw? I would not call it that. Here is a draw that is a material draw: 8/8/8/8/8/4k3/8/N3K3 w - - There is no way to win. Other draws would be by repetition and by agreement. Probably some others that I am not even aware of. I suspect that a real chess expert will hop in now, and provide the correct answer. ;-)
