TIPS FOR WHITE IN CLOSED SICILIAN:
1: ADVANCE f5 when needed, should be properly timed.
2: if.... Nf6 is played by black, f and g pawns advance to attack the knight
3: Black usually occupies d4 square with Knight. This can be attacked after moving c3 knight to either d1 or e2 and then playing c2-c4.
4: Black usually advances queen side pawns and b4 attacks Nc3. WATCH for it
5: also when black fianchettos dark squared bishop, white should exchange both dark squared bishops and weaken blacks kingside
