While analyzing my yesterday's game
I was surprised that the engine evaluated 8. ... Be6 as a mistake and suggested 8. ... Bxe3 as best move instead.
In book Understanding the Chess Openings by Sam Collins, the author has this comment on a position almost the same as here after 8. Be3 (except for the h6 and h3 moves):
> I've selected a very boring position from the Giuoco Piano to talk about captures for a moment. In the diagram position, captures are bad, and here's why:
> 1) If the black bishop takes on e3, then after fxe3 White has stregthened his centre as well as now having half-open f-file to work on. Also he's covered the d4 square.
> 2) If White plays Bxc5, then after ...dxc5 black has increased his control over d4 with his pawn and the d-file with his major pieces.
Both points seem to make sense (even if it's obvious that there are also some drawbacks). And yet, Stockfish evaluates the position after 8. ... Be6 as significantly worse than both before the move and after 8. ... Bxe3 (1.1 vs -0.1). Moreover, it also suggests 9. Bxc5 as the best reply to 8. Be6, directly contradicting both statements quoted above.
What should I take from this? Is it an example of a "computer chess vs. human chess" difference or is the reasoning in the book wrong (or at least outdated)?
