Question 1: why would you play 3.a6? It is terrible and pointless. Any other move is better.
Question 2: are you sure that your posts look exactly how you want them to look?
I think that as you improve and start encountering players who can see mate in two when it's staring them in the face, you will discard that opening

After 1. e4 d5 2. exd5 c6 3. dxc6 a6 4. cxb7 Bxb7, A few aspects stick out about this position:
Black has sacrificed 2 pawns for positional compensation. With the tempo gained, Black has played 3...a6 and 4...Bxb7. 3...a6 to prevent Bb5+, and 4.Bxb7 to control the a8-h1 diagonal.
In the short term, it would seem that Black is okay, and under practical circumstances (especially with subpar gameplay and/or short time controls) Black’s initiative may incite mistakes if White does not play the position well. Controlling the long diagonal surely increases White’s likelihood of making mistakes.
However in the long term (especially with strong gameplay and/or long time controls), going into the middle game and endgame, Black’s initial disadvantage will continue to worsen as the disparity of material becomes more and more significant.
Material advantages are permanent and usually become more dangerous over time. Initiative and tempo are temporary and only become tangible when converted into material or structural advantage (often by accurately taking advantage of an opponent’s mistakes). Initiative and tempo often give a practical advantage because they increase the likelihood of the opponent making a mistake. For a gambit to work, the practical advantage gained by initiative must outweigh the material advantage gained by the opponent. Note the game progression below:
KQRRNNBB7P vs KQRRNNBB5P doesn’t seem so bad.
KRN5P vs KRN3P is worse.
KN3P vs KNP is awful.
K2P vs K is completely lost.
This is likely what would happen with good play from both players. And unless your opponent makes mistakes (though they usually do), and unless you can exploit your opponent’s mistakes well enough while simultaneously not making noticeable mistakes yourself, the progression above, or worse, will always end up being the result.
In practice, you have to make that long bishop diagonal and that extended a6-pawn worth two pawns. That’s pretty hard, in my opinion. And there are probably easier ways to go about using the bishop diagonal without sacrificing 2 pawns.
But if you think it’s a doable strategy, feel free to try!
