No. I've already given you the tactics - K & R to the seventh and with the correct placement of the Bishop, you can force the black King off the 8th, and effect the promotion. It is there but you have to work it through yourself. No pain - no gain.

If the white rook is on the 7th, the white king can't capture the black rook on c8, d8 or e8 without it being an immediate stalemate. I think I could draw this, in the absence of proof to the contrary. And I would have no problem being corrected, as I would learn from it!

Set the position up here and see for yourself. The winning method involves white pitching his pawn for a won K+R+B v. K+R position.

I can't see a way to make progress for white, and its the wrong bishop, and its a rook pawn. Is there something I'm clearly missing?

Originally posted by MarinkatombI hear you! The hardest part is not understanding when and why I need a "waiting" move, or one of the rooks just moves up or down a file. Where does the bishop need to be in order to block a check? I need a better understanding of the ideas, in order to make the plan. I'm still trying to figure a way to get to Skeeter's original tactical position without stalemating or allowing the desperado checks (I like that term SG!)
