I'm interested in studying how to implement the "tactics table" concept by Stef Keetman in his thesis.
I remember reading it in some chinook paper a few years ago.
The idea is to detect a "one for two" exchange, ending up with a checker up of advantage.
At leaf nodes this table is probed and if such pattern is present, the position is extended to check if after the exchange the side that captures 2 checkers does keep it's material advantage.
This concept was implement in chinook with the help of Stef.
Does someone have his thesis? If so could you please send it to me?
Have you experimented this in you engines? If so was it a gain?
Many thanks,
Alvaro
