The Exchange Variation ane the King's Indian Attack are commonly played against the French. Not perhaps at Grandmaster level so much, as the understanding that these variations dont really pose a threat to the French is clear. Nevertheless, anyone wishing to take up the French must have some essential knowledge of what to do against these systems and this is what IM Andrew Martin provides on Vol 3 of his French mini-series. Both these lines are dangerous to the unprepared!
As in all his DVD's, Martin's explanations are clear and convincing,providing the listener with a reliable repertoire, suitable for all levels.
