Indeed.  But the nolot positions are carefully analyzed and you can easily find
the explanations.  I think that probably all of those are correct (along with
some other tough sets like LCT II).  This position is not one of them.

Looking at the computer output.  It is obvious that the actual game was flawed.
From looking at the proposed trajectories, the queen move is better.

If I see a *reason* why the rook capture is superior, I may believe it.  So far,
nothing but handwaving.
