Some run to trade, believing this may help them get safely to an endgame, even if they ruin their position in the process. Others are afraid to trade, because the Queen is the only attacking piece they feel confident about. When Seigbert Tarrasch introduced the Tarrasch Defense to the Queen's Gambit, many skoffed because Black often accepts an isolated QP, a weakness in the endgame. Tarrasch answered, "Between the opening and the ending, the gods have placed the middlegame." Of course, an isolated QP is often an advantage in the middlegame. One should exchange Queens, or avoid the exchange, based on the given position. Is it good for you, or bad? Don't think the Ladies' disappearance means the middlegame is over, or even that sacrifices are out of the question. The following is a correspondence game against a strong "A" player:} 1. d4 Nf6 2.
