Interesting puzzle. King nowhere to go so have to figure out how to check him.
Solved without Errors :) !
there are 2 solutions to this puzzle... if i move Rd8, the king cannot move and black cannot get any support for his king... the next move Re8 will check mate...
Seriously? What about 2...Kd6 or 2...Kd7 ?
Quite tough for an easy puzzle!
Really? Have you really thought this one through?
Is Kd7 possible black move after Re8?
Very good puzzle.
