I worked on this problem all day yesterday and this morning solving it- it is as tough a problem as you will ever find. I got what white's main winning idea is almost from the start, but it is finding out how implement it that is so challenging- black can defend every try except for one, and finding that one right method is like trying to find a particular needle in a stack of needles. Right now, I am working on the problem that shared 1st prize with this one- can't see how that happened, but will know more later.
Yancey, is my first move correct?
No and yes, Alena. You are on the same track I was at the start. You should, though, finish out the path outlined by 1.d5 etc.
1.d5+ Bxd5 2.Rxd5 h2 3.Kc8 Ra1 4.Rg6+ e6 5.Rd6+ Kc5 6.Rg5+ e5
Am I on the right track?
