Wolf in Sheep's Clothing (Why NOT to play 1. a4)


How does 13. f3 benefit white? He would just end up losing his Queen...
Also, I know he made several mistakes, that is obvious (and the point of this post). My question is, how well did I capitalize on them?

apart from losing a tempo and not being able to play Morphy Defence to the Black Spanish Game, i don't see any benefit or problem with 1.a4 from this game. the a4 square doesn't do much (it certainly won't help a white b5 bishop which is the only piece that ever likes to sit on b5) and is hard to get at.

a4 would have been justified in the variant 1. a4 e5, 2. e4 Nf6, 3. Nc3 Bb4, 4. Na2 ! , although it does not give white any advantage, either .
(That strange-looking retreat, has been tried in the Ruy Lopez, too:
1. e4 e5, 2. Nf3 Nc6, 3. Bb5 a5, 4.0-0 Na7 .)
In the game, after 4. Nf3 B:c3, 5. bc (better dc) N:e4, 6. Qe2 was necessary, still with a reasonable game after 6. ... d5 , 7. d3 Nf6, 8. Q:e5+ .
Instead, white should have lost after 6. N:e5 ? Qe7! , 7. d4?? (loses a piece, better was d3, which only loses a pawn) d6! , (and not d5?, as in the game).
Also, white, in move 11, could have taken the pawn on d5:
11. B:d5 N:d5, 12. Q:d5 . I don't see a compensation for black.

Here is a game where White opened with 1. a4, and I chuckled softly. However, at several points (had I made a mistake) the game could have gone to White. Let me know what you think of my play.
Thank You!
