9.Qe2 Rather than play the common plan
of the Queen N's development here (usually to c3 but sometimes to d2 to pressurize d5 or e4 respectively),
White chooses a rare, and thus less studied line, where Qe2 is played in conjunction with Rfd1 and the
development of the Queen N is delayed until the central position is more clarified. However,Bllack counters
all this with an innovation on move 10.
