OK, I was assuming you meant "mate in 6" was that white could mate black in 6
moves (or after about a 12 ply search).  I ran a few programs for several minuts
and none of them saw a mate for white.  Now I think you simply meant white gets
mated in 3 (after a 5 ply search) if QxR.  In any case, Bob Hyatt's earlier
comments about not null-moving in check certainly apply.
