The other responses, which show that some chess engines do find this move eventually, show something else as well: "Strong chess engines are sometimes useful for finding new ideas." This may seem too obvious and trivial to mention. Nevertheless, it can have a profound impact on the future development of chess opening theory. It is also important in the middlegame and maybe endgame because it can make post-mortem analyses more colorful. Sometimes the chess engine can find an "impossible for a human to find" kind of move. That is one of the reasons why I let Fritz &/or other engines do an "overnight analysis" before I study an annotated GM game. Sometimes the GMs simply miss brilliant moves which are found by the engines. It also happens that such surprise moves come up in detailed engine analyses. Bob D.
