ElTurco 0.91: 2004-11-28

• Add draws by lack of material. With it all the rules of chess should be implemented.
• Added a -r option which makes the program resign when it's a rook behind
• Fixed a bug in the tranposition table. It wasn't being used after the first game
• Fixed a bug in the non blocking input handling. Should work ok in windows now.
• Limited internal iterative deepening to PV nodes.

ElTurco 0.90.0: 2004-11-27

• Fixed a nasty bug in see_sort() where the best captures where not considered.
• Added perft support. The command is perft <depth>
• Fixed a bug in castling move generation where a pawn in front of the king would not stop it from castling
• Allowed promotions to something other than a queen.
• The size of the transposition table can now be specified in runtime. The command line option is -t <num entires in table>. The actual number of entries used will be the highest power of 2 which is lower than the specified number (so if you use elturco -t 400000 you get 262144 entries).
• Limited the lazy evaluation a bit. It was making too many mistakes.
