[edit] Sicilian - O'Kelly variation
[edit] 2...a6
This early a6 prevents White from occupying b5, so after 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 and then 6. Nb5 is prevented. The main problem with this variation is how to deal with 3. c3.
Often White falls for the following trap: 1.e4 c5 2.Nf3 a6 3.d4? cxd4 4.Nxd4 e5! 5.Nb3 Nf6 6.Nc3 Bb4 7.Bd3 d5! and Black has a clear advantage. He is simply too active.
