1...c5

[edit | edit source]

Black invites a transposition into the closed Sicilian, 2. e4.

If White wishes to avoid (or, at least, delay) the transposition they can try 2. Nf3?!, where 2...Nc6 3. d4 cxd4 4. Nxd4 is a line Schiller christened the "Sicilian two knights,"[1] though White has the accept the possibility of 2...d5.

2. d4!? cxd4 3. Qxd4 Nc6 4. Qh4?! is the Novosibirsk variation, as Schiller calls it.[1]
