Ok, here are the variations we have been waiting for!After:1. e4 d52.exd5There are 2 options for black:2... Qxd5This is the most obvious reply, and the most common as well. It is the main line because of its popularity and because it was played in the 1475 game with the Scandinavian. White generally follows with:3. Nc3.Then Black must decide where to retreat the queen. 3... Qa5 is the most popular and logical, because it controls the center, does not get in the way of other black pieces, and is hard to attack from her a5 post. This is what I would play.3... Qd6:This is called the Bronstein or Pytel variation, which is very popular nowadays, and there are several books on the market now. I have not done much reading on it, and stick with Qa5, but for the sake of the group I will dive a little deeper into it.3... Qd8This was played in 1475, and is now considred rather dubious because it basically reverses the development that Black has already done. This is not a good variation.3... Qe6+This is called the Patzer variation, is also not very wise, as it blocks the e pawn, forcing the Queen to move again.3... Qe5+This, followed by Qg5, was used by David Norwood against Garry Kasparov. Kasparov quickly won, as the plan is rather dubious.3... Qc6??Loses to 4.Bb5 pinning and winning the queen, but, sadly, some people will play this against you! But now you know, do not make this move! Conclusion:Qa5 and Qd6 are the best Queen retreats, and you should do some more research on each to decide which you prefer, but I reccommend Qa5.In my next post in this topic, we will discuss 2... Nf6, which is very popular, and also discuss several minor options for Black.
