Jerome Gambit: Return of the Centaurs

In a complicated position, White's attack breaks through.

Checking the notes, you can refer to a number of human + computer games. As I wrote in a post 6 years ago in "Jerome Gambit: Centaurs"

Recently Bill Wall sent me 16 of his Jerome Gambit games that were Human + Computer vs Computer encounters. Such teamwork is sometimes referred to as advanced chess, or cyborg chess, or centaur chess.

11.Nd5+ Kd8 

A stronger response than 11...Kf7 seen in Wall,B-Guest5541035, FL, 2014 (1-0, 17).

12.Qg3 Qe6 

Stronger was 12...Nd3+ as in Wall,B - BBchess engine, Lahore 2015 (1-0, 51). 

13.fxe5 Ne7

Not 13...dxe5 14.d4 as in Wall,B - Aburasian, Chess.com, 2010 (1-0, 33). 

14.d4 Bxd4 15.Qh4 Kd7 16.Rf6 

The position is getting complicated, as White attacks.

16...Nf5 17.Rxe6 Nxh4 18.Re7+ Kd8 19.Bg5 

19...Nxg2+ 20.Kd2 h6 21.Rh7+ hxg5 22.Rxh8+ Kd7 23.e6+ Kxe6 24.Rh7 Ke5

His Rook will outplay Black's two Bishops, and it looks like White will wrap things up - but not yet.

25.Re7+ Be6 26.Nxc7 Be3+ 27.Kc3 Nf4 

Black's chances for survival lay in pinning White's Knight to White's King: 27...Rc8 28.Rxd6+ Kf4 29.Rf1+ Kb4 30.Re7 Bb6 31.Rff7 Bg1 32.Kb4 Bxh2 and White will work hard to take the full point.
