This sound to me as something completely new. Keeping two worst moves for
something useful. I never did this and I have no idea where it can work. In mine
each ply is devided by two parts: "active" and "passive". The last best move is
saved as best "passive" or "active". And program use each time the best "active"
or "passive" even if sometime this "best move" is not from the last one.

You can find the best for your program only on the place and by statistics
because nobody can guess exactly how your program is written. Few time when I
looked into somebody else code, I was all the time impressed by huge difference
with my writing.
