TooThought! and FFO Endgame Test Suite

Starting with TooThought! 1.6 fixpack 5, I have measured the behavior of my program on FFO Endgame Test Suite. The test has been performed using the following configuration:

For each position, the best line is showed for the first six moves.

Results for Exact endgame

Here are the results for Exact endgame search. For perfect endgame analysis, TooThough! performs a WLD search first and then, using WLD result, goes into exact endgame phase. A less aggressive forward pruning is used at this stage.

For games ending with a draw, the analysis is stopped after WLD search and the results reflect the cut strategy used in such phase, in particular the best line could be incorrect for the same reason mentioned above.
