Reversed Damiano Gambit (with c3)

It arises from the rare King's Head opening (1. e4 e5 2. f3) or MacLeod Attack (1. e4 e5 2. c3). The initial Reversed Damiano Gambit position:

The following moves are straightforward:

Here SF10+ suggests the obvious 6...Bc5+ [ev=+0.4, d=22].

Now 7. Kg3 leads to a beautiful forced mate in 11 moves! I leave you the pleasure to find it yourself.

The following position is also straightforward:

Here there are 2 best moves: 8. b4 [ev=+0.2, d=25] and 8. Bd3 [ev=+0.1, d=25].

I think I will not play as white  

I doubt anyone will play this... 

Thanks Yigor for this post, very informative and useful, as usual with you!

Here u just have to study Damiano defence, then just compare with what Yigor proposes.

This post could be informative if Yigor would give how to handle Damiano defence, then what happens if playing the same way reversed with c3 added.

This could be a nice lesson, but don't expect Yigor to explain chess (giving names and evaluations from engines is not really instructive but it is what he always does)...

Lol, you refering to me.

I am telling you, OP post is useless to learn.

There is no point for white to play double suboptimal moves like 3.f3?? 

2.c3 is playable , but not strong and white can choose some better stronger moves, such as Nf3, d4, Bc4 , Nc3 etc. After c3, White must follow up with 3.d4. for synergy.

After 3. f3???  white played so much suboptimal moves that black can even play with sacrificing a pieces.

Regarding openings, I already learned all variations of Encyclopedia of Chess Opening 500 at least once, several chess informats , replayed at least 5000+ master games in my computer etc. (Those I learned in my teenage 20 years ago). I still remember a significant theory lines.

I am using engines currently cos 

1. I really dont trust human moves anymore

2. I am part of engine development community.
