Readiness Test

So, you consider yourself ready for rated games. Admirable confidence — let's see what's backing it up. Three tasks: castling-960, mate in one, and a position assessment; a couple of minutes for all of it, if you don't sit there staring at the ceiling. Pass — and I'll unlock the rating, and your wins will start meaning something. Fail — no tragedy, come back after the lessons, I'll wait. I always wait.

Task one — the signature dish of 960. King on b1, rooks on a1 and h1: one right beside him, the other across the whole board. Make either castling — kingside or queenside, I don't care, as long as the gesture is right. Anyone who starts shuffling the king one square at a time here still hasn't grasped the point.
