The fianchetto bishop is super strong, and while White's c3 pawn guards the d4-square, and Black's d5-square is weak.Qc711.Ne3⩲10....b511.a4b412.Rd1Be613.Nc4Qb814.Qe2h615.Bd2Rd816.Be1Rxd117.Rxd1bxc318.bxc3Qc719.Nfd2Rd820.Ra1Na521.Bf1Nxc422.Nxc4Bc823.f3Ba624.Qa2Bf825.Rb1Bc826.a5Nh727.h4Kh827...g5!28.Qb2Ba629.Ne3⩲28.a6!...Keep an eye on this pawn!
