Not only subsets of the board are possible pattern. A pattern of a position might be ofcourse a Kg1 or a Ph3 but also a R somewhere on the h file or a rook on any open file, the number of pawns, Queens on board, having the pair of bishops, ... and ofcourse also distances between a piece and an subset of the board or a particular square. I will not stop the computer to find something important I did't think of. But I am not very interested in patterns I can't find in my huge amount of games or in patterns that don't tell me something about the probability whether game will end in a win, draw or loss. Ingo And with a, b being patterns also a||b and a&&b are pattern candidates.
