As I had said earlier the joker gains the power at the end of the opponent's move and retains it until the next time the opponent moves. I could have made myself not clear enough. So if the joker is unobstructed on the same diagonal like the enemy king it pins all bishops and queens the enemy has, because it would mean that the opponent has moved into check!
The power is almost in full (so Fergus in your question it is number 2). That is because the games could be quite imbalanced if a joker promotes to queen and a joker can easily move across the board compared to a pawn. Once again there is no castling in this game but some leaps for the unmoved king.
