How many patterns does a master know?

@KingJames look at my earlier comment #4
E.g. I put a king on one square. The other king has a minimum of 53 squares to go on, and the bishop on any of the remaining.
So 64*53*62=210,304 positions.
Double for the bishop of the other player. Double to include the calculations for a knight.
841,216 positions even the worst beginner will be able to evaluate instantly.
I don't know the exact definition, but chess patterns are not chess positions. They are some kind of piece arrangment with geometrical properties your mind can identify.
You find the same properties in another similar position and you notice the pattern.
So in the case of opposite coloured bishops, I guess there are only a couple of related patterns (blockading patterns, bishop controls the opponent passer patterns, two passed pawns on opposite sides of the board patterns, sacrifice against two connected passers pattern...)
