Hi people,

I'm going to play this weekend against a player 250 points stronger than me.

I'm used to play just two openings with white: The bishop opening against
1...e5 (with d3) or the king's indian attack.

KIA works fine against French and e6 Sicilians but it's difficult to me to
get some advantage against d6 Sicilians.

Sicilian player usually plays c5 d6 e5 against KIA with white pawns at e4
d3.
Against the black structure the white's goal may be to play f4 but, the
knight at f3 slows this "manouvre".

I tried, sometimes, the closed sicilian. It seemed to work better to me to
get a king side attack than KIA Probably just because the king knight goes
to e2 freeing the way to play f4 as fast as possible.

What would you try, KIA or Closed Sicilian, against a sicilian player?

In a Closed Sicilian should white play f5 as in the King Indian Defense and
try to open the g column after the g4-g5 advance?
Or
Should maintain the pressure over e5 ?

Thx
