Analysing My Own Games: Bishop vs Knight

Analysing My Own Games: Bishop vs Knight

Whilst my game only went 20 moves, with 1 move deviating from theory (and being decisive), I learnt much from analysing the typical Fischer endgames of Rook and Bishop vs Rook and Knight that can arise.

 

After my opponent exchanged Knights early with 8. ... Nxd4 in a Richter-Rauzer, White has a nagging initiative reaching a key position which has occured 11 times.


Crtical Endgame Position








 

Why is White scoring nearly 73% in this position?

White's pieces are more active. He can create a Queenside pawn majority. He can penetrate the 7th rank.

Really the lesson from this game was exploring endgames arising from this position.


White to Move


My Game Annotations and Analysis 


Model Games
We see the transfer of the Rook along the 4th rank to infiltrate either at the 7th or 8th rank.
 
Advance of Queenside pawns. Even after the exchange sacrifice, Black's Rook can't stop the advanced pawns.
 
The dominating Bishop over Black's Knight.


Model Game

 
By fixing the pawn at b6 and tying the Black Rook to the a-pawn, White sits on top of Black.
He uses two weaknesses to switch to the Kingside. Ultimately Black's Knight is trapped on the side of the board, highlighting the good Bishop vs Bad Knight.
Observe how White's forces advance as a unit to Queen the pawn.

Model Game

Here we see White energetically seizing the 7th rank and ignoring threats to his e-pawn, as Black's doubled e-pawn remain impotent.
 
With 3 connected passed pawns on the Queenside, this proves too much.
 
Further illustrates the Bishop dominating the Knight in this endgame.
