The full game score provides exact position-repetition information and 50-move draw rule information that something like sending a FEN string cannot. It is by no means difficult to see if the new position is an evolution of the game from the old position. UCI makes this the responsibility of the engine, not the GUI, but it's not particularly onerous. Presumably this choice was made to simplify overall use of the protocol. There are other things about UCI that aren't the best, but I don't see a big problem here. Dave
