Restricted Rook Runaround (Posted on 2016-01-05) Difficulty: 4 of 5
A king and a rook are on opposite corners of an 8x8 chessboard. The king is trying to avoid being checked by the rook. Normally the rook would check the king in one move but this rook is restricted - his moves are limited to up to two spaces, that also applies to his ability to make the check.

Can the king avoid check indefinitely? If not, how long can he last?

Question Difficulty 4? | Comment 1 of 7
Well, obviously the rook can check the King in a very small number of moves.  How long the king can last is just a function of who moves first.  So why is this difficulty 4?

The only difficulty I can think of is that the rook is perhaps required to check the King in such a way that the King cannot immediately capture the rook  In other words, the rook must be exactly two spaces away from the King when it gives check.  The problem does not require that, but I suspect that is what Brian has in mind.

Is that in fact the problem?
