An ambitious setup. By leaving the f-pawn unblocked, White intends to meet
Black's planned ...f5 with f4, which could cause Black some problems with his
development. However, the knight's placement on e2 is not always favourable;
sometimes he will have to spend two tempi on the manoeuvre Nc1-d3. On the
other hand, after Nf3 White would most surely play Ne1-d3, which implies the
same investment of time.} a6 {Black is in no hurry to carry out the standard
