Some characteristically excellent advice from Paddy there.
However, in my opinion 3...Nf6 against the Italian is only practical if you are the type of player who doesn't mind being a pawn down for nothing in particular. It may well be theoretically viable, but some people just don't like that. And the higher up the tree you get, the more 4 Ng5 you'll see.
(...)
Of course, the debate about the Two Knights with 4 Ng5, especially the traditional main line with 4...d5 5 exd5 Na5, has been going on since at least the Steinitz-Chigorin argument (Black definitely won that one) and in some ways is symbolic of the struggle between static and dynamic factors which one could argue is really at the very heart of the game of chess.
In the White camp (extra pawn, better structure, offside black knight, so White is better...) we find such titans as Steinitz, Fine, Fischer and Short, joined recently by younger players who have grown up trusting the computer more than the judgement of their “great predecessors”: Morozevich, Nakamura, Sutovsky...
In the black camp (space, open lines, activity + initiative = sufficient compensation) we find giants such as Chigorin, Tarrasch, Lasker, Keres, Botvinnik (!), Bronstein, Gligoric, Tal, Beliavsky, Romanishin...
We also find some players who are willing to take either colour: Timman, Ivanchuk, Kariakin...
There is no doubt that Black has an easier life with 3...Bc5 and that 3...Nf6 makes greater demands on Black’s energy and creativity – the onus is on Black to prove that he has sufficient dynamic compensation. Thus, since 3 Bc4 remains far less popular in master chess than 3 Bb5, it is entirely reasonable for most of the professionals to reduce their preparation burden by choosing 3...Bc5, rather than invest a lot of time preparing 3...Nf6 when this work might only occasionally prove useful.*
Similar reasoning explains many of the opening trends among today’s professionals (exemplified by the rise of the Slav and the decline of the King’s Indian). Dynamic lines tend to require far greater preparation and maintenance, especially in our age of the computer, and so it is natural for masters to want to reduce their work load, or at least leave some time to work on other aspects of their game (e.g. visit the bar). **
Thus the general trend, certainly in all-play-all tournaments, seems to be back towards the “press with White, make a draw with Black” approach. ***
John’s viewpoint seems to me to be unduly pessimistic and perhaps just a touch over-influenced by computer evaluations. Of course, he might well be proved right about the Two Knights, but I think that would be a sad day indeed for our beloved game of chess.
* [At lower levels one sees 3 Bc4 much more often, Whites are often not well prepared and defend poorly, so there is greater worth in preparing 3...Nf6 in depth, for utilitarian as well as chess-educational reasons].
** [There are only a few top players like Ivanchuk who seem to be prepared to play almost anything.]
*** [Of course in Swisses one still needs to win some games with Black to finish amongst the top prizes.]
PS Thank you for your kind words, John!
