39 ( +1 | -1 ) I think that usually the Sozin Variation refers to the Fischer-Sozin Attack (1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Bc4). I'm not sure what 5... e5 is called, but 6. Bb5+ intending 7. Nf5 is a good (practically only) response. The Najdorf tries to avoid the Bb5+ problem by playing 5... a6. Ndb5 is played in other situations where ...d6 has not been played yet where white threatens Nd6+, for example 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 (Sveshnikov).
25 ( +1 | -1 ) I agree with you, AtrifixI think that the Sicilian described by chris21 is the little sister of both Pelikan/Sveshnikov (B33+) you described, and the L÷wenthal/Kalashnikov (B32 - 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5)
16 ( +1 | -1 ) TranspositionIsn't there a simple transposition to Pelikan (orr Sveshnikov) variationa after 6...a6 7.Na3 and 7. Nc6? I'm not an expert here, so I might be wrong. Transposiotions in Sicilian is a damn tricky thing.
19 ( +1 | -1 ) Thanks for all your replys. Chessmaster seems to think its the "Sozin Variation" as noted above. But Atrifix is correct about the sozin attack with Bc4 in the Najdorf.
