Thanks for this information. The next version of Queen
will accept, for example, the queenside castling
availability for Black only if the black king is
on e8, a black rook on a8, and nothing in between.

As for this position, corrected into
2r1k2r/2pn1pp1/1p3n1p/p3PP2/4q2B/P1P5/2Q1N1PP/R4RK1 w - - bm exf6; id
"LCTII.CMB.06"; c0 "Lilienthal - Capablanca, Hastings 1934";
with no castling rights for Black, this took
Queen 40' (solution on depth 12).

I also tried
2r1k2r/2pn1pp1/1p3n1p/p3PP2/4q2B/P1P5/2Q1N1PP/R4RK1 w k - bm exf6; id
"LCTII.CMB.06"; c0 "Lilienthal - Capablanca, Hastings 1934";
with kingside castling right for Black, which took
59' for Queen to solve (also solution on depth 12).
My machine is a Pentium 3, 500 MHz.

I would never have found this move exf6 myself, but then
I am not a very good chess player.
