A Study...with Diagrams!
The really important thing, however, is that the diagram problem has been solved! (Many thanks to DG of the Boylston Chess Club and their fine blog- see his comment here for the how-to details.)
White to move and draw (but Black is the one needing to save the half-point)
White can draw this lots of ways, but the variation illustrating the neat point goes like this:
1.Rf1+ Re1 2.Rxe1+ Kxe1 3.a6 h3 4.a7
and now Black must play accurately: 4...h2! (4...hxg2? 5.a8Q g1Q 6.Qe4+ Kd1 [6...Kf2 7.Qe2#] 7.Qe2+ Kc1 8.Qc2#) 5.a8Q h1Q 6.Qa1+ (White has no other way to progress) Kf2 7.Qxh1 stalemate!
