Counterplay played an engine online and after the moves 1. e4 c5 2. d4 Nf6 Counterplay was out of book, which surprised me since the position looked rather err, normal. Counterplay played 3. e5 and the engine it was playing responded with Ne4, which is just bad. I looked it up in my 2.4 million game database and found 15 hits, and at first couldn't figure out why Counterplay's move 4. Qe2 which wins a piece wasn't played at all. (Other moves work too, but some are a little less convincing.) Then I looked at who played the games, all weakies from the ICS. Lesson: Use your head, and the DB as a reference tool, but ALWAYS think for yourself. JW
