Richter-Rauzer Attack

The Richter/Rauzer Attack is a continuation to the Sicilian Defense chess opening. I have seen different orders of play but all the pieces that are moved before, 6.Bg5, must be moved. I use this attack whenever my black opponent plays 2. ... Nc5. Here is the chess notation,

1. e4 c5 
2. Nf3 Nc5 
3. d4 cxd4 
4. Nxd4 Nf6 (I’m not sure why nobody plays 4. ... NxNd4)
5. Nc3  d6
6. Bg5 (this makes it The Richter/Rauzer)

There are different ways of proceeding at this point but the general idea is to put pressure on blacks queen to threaten to either exchange queens in a way that takes away blacks ability to castle or to take blacks queen. Here is a good demonstration of the Richter-Rauzer which is also where the opening gets its name,

Richter-Wagner, 1932

Nobody plays Nxd4 because it would lose a tempo, in so doing bringing White's queen to a commanding post from which she is pretty unassailable. It is almost never good for Black to play N(c6) x N(d4) unprovoked in the opening like this -- not in the Scotch, not in the Sicilian.

That lemma about "don't bring out your queen in the opening" is a huge stumbling block for so many players. It should be "don't allow your opponent to gain time by attacking your queen with developing moves, or moves that otherwise improve his position", and "don't prematurely determine the position of your queen without reason". Early queen moves are fine, indeed necessary, in many openings.
