What about the Ivanchuk/Carlsen line 5.Nb3 Bb6 6.Nc3 (or 6.Qe2 first)? No a2-a4 stuff.
White seems having a good game (and an aggressive one, at that).
Maybe Black's best is the interesting "new" try 5...Bb4+!? which isn't even mentioned in a recent thick book by Dembo and Palliser.
I recently started playing the Scotch game as White and I was wondering about your impression as to which line after 1.e4 e5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Bc5 offers most practical chances for White in tournament play.
I mean, people seem to have become well prepared for the complications after 5.Be3 Qf6 6.c3, as I've even seen one game today in a database (played last year) where a player rated app. 1800 played first 16 book moves of the Qg6 line, outbooked the higher rated White player (2100) and eventually won.
I've also seen a lot of recent GM games featuring both 5.Nxc6 Qf6 6.Qf3 bxc6 (which seems to be more populat atm than 6...dxc6) and 5.Nb3 Bb6, etc. with good result for White. Of course, in the former, one has to be prepared to play the following transition to the endgame well, but if one :is: good in endgames, this does make sense... The other line seems to be quiet and also more oriented towards positional play, right?
So, in your experience, what is the most flexible way of handling the White side of the Scotch, in practice, without memorizing many tactical lines to great depth and constantly following novelties? I know it must be also a matter of taste, but that aside, what is your personal experience/advice? Thx.
