easy but good
Its not in 7, you have check on the first rank so in 8.
Odd ,Friday continuation. Pretty good puzle yesterday and today.
why are you chasing the black king around the board? force it to its home row and mate. White plays R-k4, Q-b5, R-k6, Q-b7, R-k8mate. As long as black makes legal moves it makes no difference where he moves in response to the white moves. White only has to watch the queen diagonal to insure a stalemate does not develop.
