The first volume dealt with the Najdorf and Scheveningen variations, and it is now time to pay attention to three other extremely popular systems: the Taimanov, Kan and Richter-Rauzer variations. After careful consideration within the Thinkers Publishing team, we decided that it made sense to group these variations together. In particular, the first two are closely related and share the feature that, in both cases, Black plays ...e7-e6 and ...a7-a6 at an early stage. They typically have the idea of retaining more options for their king’s bishop by postponing ...d7-d6 (or even omitting it entirely.) The bishop may go to b4 or c5 in different lines. The Richter-Rauzer is, in theory, just one of the possible developments from a Classical Sicilian. We have already dealt with a few games that started with the Classical and where Black shortly played ...e7-e6; and 6.Bc4 (the Sozin variation) was rightly treated within the Scheveningen pages. However, it is clear that White’s most popular counter, the Richter-Rauzer variation (6.Bg5) deserves separate attention.
