On 2.Nf3 Nc6
Mae and Jay R follows the basic principle:
Bring out Ns before bringing out Bs
Capablanca in Chess Fundamentals

On 3... Bc5
This logical looking move is actually a mistake because White can simply play 4.Nxe5 Nxe5 5.d4 with a slight advantage.

On 5.O-O O-O
One of the most important guidelines in chess is to protect your K from harm. - Watson in Mastering the Chess Openings

On 7.h3?
As Quesada and GM Torre wrote in Beyond the 13th Move, "Theoretically, this is unnecessary and a waste of tempo in this early part of the game."

On 8.Bg5
In the opening, a B is best placed for attack when it controls a diagonal passing through the cnter or when it pins a hostile N and renders it immobile.
Chernev in Logical Chess

On 8... d6?
Logical but wrong. According to Rybka, the best is 8... Be7 to defend against 9.Nd5.

On 9.a3?
This is another waste of time as 7.h3 and a missed opportunity to get the advantage with 9.Nd5 (+0.83 on Rybka's scale).

On 9... a5?
A counter waste of move. The best is to challenge White's active B by 9... Be6.

On 10.Qe2
This allows B to equalize, still the best is 10.Nd5.

On 13... Bd7
Black gets a slight advantage by 13... Nxe4! Check out how.

On 14... Qc8?
This is a blunder, allowing 15.Bxf6 with a resulting break-up of the castled position. Nxe4 is still possible.

On 15.Qe3
White is already winning with 15.Bxf6 +- (+2.09).

On 15... g5?
One of the most common eaknesses occurs when an ill-advised pawn move is made in front of the K.
The Modern Art of Attack

On 16.Bg3
White wins with the bold 16.Bxg5 hxg5 17.Qxg5+ Kh7 18.Qxf6 +- (+1.56).

On 16... Re8
Black has a counter-attack and gets a slight advantage with the daring B-sacrifice 16... Bxh3 (-0.29 on Rybka's scale).

On 17.Nd5
Centralizing the N is good but the best is 17.f4 +-.

The records of Mae and Jay R are incomplete at this point.
