The new version of Vortex makes use of an "incremental hash table". It stores some of the "deep danger" from the previous search, so on its next move, it can find the "fail low" type of moves much sooner. Much of the play for Black is improved with this technology. It sees the danger, on average, 2 plies sooner, since "it" makes a move, "you" reply, and the "worse" positions for it saved from the previous search are hit without having to evaluate the positions or call the move generator. This makes the nodes/second creep up gradually as you play the game.

It is a very impressive win, combining strategy and tactics in the perfect way to defeat the software. Bascially, George got into a strong position, sacrificed material, then created a position where the program had so many legal moves, the game tree basically exploded, and it could not search very far at all.

A subtle way to win, and very hard to do!
