the mouse cursor over a piece

Technical Information
Here's
some information for those who are interested in chess game engines:
- The search algorithm is a min-max search with
alpha-beta pruning
- HiddenLynx uses iterative deepening to
maintain nearly constant thinking time for each move. The iterative
deepening is enhanced with the principal variation line (i.e. the
previously best branch is searched first when the next deepest level is
searched)
- To further speed up the search, HiddenLynx
uses killer heuristics (i.e. it considers the moves of the strongest
pieces first)
- The evaluation of the board is based on the
"mass" of the pieces and an additional position map, which ranks strong
positions for each piece type with a higher value.
- On a computer with a 3.2 GHz CPU, Hiddenlynx
searches roughly 7-11 plies in 10 seconds.
