I’ll be making a DVD on this opening so right now I’m showing a special interest. I like Jan Pinski’s book on this opening but there again he gave very little space to the traditional line of 4.Bb5 Bb4. At one time this was one of the most fashionable openings, but 4…Nd4 changed this forever.
Of course the theoretical verdict of it being drawish (4…Nd4 5.Nxd4 exd4 6.e5 leads to simplifications) does not affect the practical problem of how Black should play for a win. But it’s always possible if you that’s what you really want.
