Alpha-Beta Conspiracy Search is an alpha-beta search. It avoids all deficiencies
of Conspiracy-Number Search. Alpha-Beta Conspiracy Search uses conspiracy theory
to extend the nodes, but works within alpha-beta. The memory cost is linear.

I like very much its behaviour to extend nodes near the minimax score and search
less deep other variations. The future of selective search?

Does someone have any experience with this interesting method?
