I usually do the Open Variation as White (e4 c5 Nf3 Nc6 d4) or the Lasker Pelikan (e4 c5 Nf3 Nc6 d4 cxd4 Nxd4 Nf6 Nc3 e5) as Black. The KIA is a completely different opening setup with different theories behind it. The closest Sicilian variation would be the Dragon.
I have trouble playing against the Sicilian. Just wondering what the club members play.
