SICILIAN DEFENCE
The Sicilian Centre Game
Black rejected the centre but sought control of White's Q4(d4) for a queen's side counter-attack.
White rejects Orthodox and other lines to advance his Queen's Pawn early, challenging Black's QBP so as to play a gambit (the Morra QBP) if Black takes his QP (usual!) to prevent 3.P-K5. W-Alt.
    White   Black
 1. P-K4    P-QB4
 2. P-Q4!?	    Transp.from Benoni
BLACK to Move or Undo or Jump or Clear
