That's some number of patterns, with 2 million of games there must be at least 150-200 millions of positions. There is probably every strategic and tactical maneuver of practical use in there, as well as much of the interesting endgame positions. If only one could use more than just exact match for the openings, it could make some truly humanlike play. The problem with current programs is that they don't make use of openings the way humans do, i.e. by keeping in mind typical patterns or themes of play following a given opening line. Humans get this by examining complete games of a given opening, so they can see the purpose and potential of the achieved configuration. Some sort of dynamical evaluation function (which might work only at the root level), tuned to the sample games from a given opening (e.g. to value more certain piece/pawn activity, or control of given squares, or value of pieces and an "urge" to move given piece), should be able to pick up some of that pattern from the remaining parts of the games. (If I ever get my program beyond the planning and gathering phase...)
