The positionally desirable} 10... bxc6 {runs into} 11. c5 $1 {which seems more
pleasant for White. Black has to scramble tactically to justify his worse
structure.}) 11. Rd1 Ne4 {Here McDonald writes: "This is the move Black wants
to play - he responds to White's decentralizing queen move with a
counterattack in the centre that gets full value out of 1...f5. However, we
can't always play the moves we want, even in the Dutch - so can Black get away
with it? The question is whether the resulting dynamism will compensate for
the weak pawn that appears on e4 and Black's generally reduced control of the
light squares." This is very fair and objective. The problem is that McDonald
does not provide an alternative continuation to fall back on if 11...Ne4
encounters a problem.} ({
