Jan, I don't like castling in studies much either. So 2 points, despite the pleasant flow of the solution. Arpad's rule of 3 points to Costeff has its exceptions.

I agree though I find the intro with Kxd6 Rxd7 ugly. The point is Ra5, but this is not worth more than 1,5 points and can certainly be implemented better. Castling is difficult to realize, but has no extra value (similar to en passant). Although, talking about en passant, there is a good recent study on that theme by Yochanan.
