Star Trek TNG Chess Advice or How Troi Surprised Data

"A characteristic response to the Kriskoff Gambit is to counter with the El Mitra Exchange, particularly since I have already taken both of your rooks.  By missing that opportunity, you have left your king vulnerable."

"We'll see."

"As you wish, Counselor.  Check.  Intriguing.  You have devised a completely unanticipated response to a classic attack.  You will checkmate my king in seven moves."

"Data, chess isn't just a game of ploys and gambits.  It's a game of intuition."

"Hmm.  You are a challenging opponent, Counselor."
