By the 6th move, Rhal and Kevin have followed the basic principle "Develop Ns before Bs" (The Ideas Behind the Chess Openings).

On 8.h3
Quesada & 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 9... Be7
Chernev wrote in Logical Chess, "Defensively, the B would do a fine job at e7, where it radiates power in several directions, making an intrusion by an enemy piece difficult."

On 10.Be3
Rybka recommends 10.O-O and GM Seirawan wrote in Winning Chess Openings, "The purpose of the opening is to get a safe K and an equal middlegame."

On 10... Rc8
Rybka also recommends 10... O-O.

On 11.Rc1
Rybka's #1 choice is 11.O-O which shpuld be answered similarly; 11... O-O for as Evans wrote in The 10 Most Common Chess Mistakes, "Nothing is more important than safeguarding your K by castling early, within the first dozen moves, if possible."

As Antonio Banderas said in The Mark of Zorro, "As safely as possible."

On 12... Ne4
This is a blunder, according to Rybka. Better is 12... Nd7.

On 13.Bxe4
This is the best move, giving White the advantage (+0.98 on Rybka's scale).

On 14.Nxe4
Rybka shows that the best continuation is 14.Qg4.

On 14... Qd5
This is another blunder and Rybka's top choice is 14... O-O.

On 15.f3
White did not find the best continuation which is 15.Qg4 (+0.71 on Rybka's scale).

On 15... O-O
Black has equalized!

On 16... f5
This is a blunder. The simple 16... Qxa2 maintains equality.

On 17.exf6
The logical and correct move which gives White the advantage once again (+0.71).

On 21.Rg5
This is a mistake which allows Black to equalize; the pawn at d4 will fall.

22... Qg3
The best to maintain equality is to capture the pawn at d4; Nxd4 or Qxd4.

On 26.Re1
The winning plan is to force an exchange of Qs by 26.Qe4. As written by Nimzovich in the classic book My System, "Simplification is desirable if we have superiority in material."

30... Nd5
This is a blunder, the pawn at a7 is precious. As Golum said in The Lord of the Ring, "My precious."

31.Be3
The simple 31.Bxa2 wins already.

31... Ke7??
The R is en prise.
