I was hoping to find some ideas on how to kill the King’s Indian but nothing much came up this week.

What do you recommend for White?

The game was equal for a long time until mistakes decided the game late in the endgame.

After 23..Bxe8(Diagram)

Opposite colored bishops can have drawing tendencies in certain endgames but in a middlegame the side with the initiative effectively has an extra piece on ‘their’ color

Conventional positional logic suggests that White should play on the dark squares and black on the light squares. Black’s minor pieces are slightly passive but there are no obvious weaknesses. White has more space but the doubled c-pawns are not really weak.

After 13.g4(Diagram)

White wants blood and with this in mind left his king uncastled and launched the attack with 13.g4

Black has gone about his business, completed development and secured his king.

The Positional Advantage in Rook Endings

One type of structural advantage is fewer pawn islands. Pawns can also be isolated, doubled or just easy to attack.

Here is a nice example of multiple types of pawn weaknesses with equal material in double rook ending.

White to Play(Diagram)

White has the healthier structure and plenty of targets. Both rooks are actively placed on the c-file and the a-pawn is isolated. The doubled g-pawns are not attackable but have reduced flexibility.

White is attacking the c6-pawn while Black is also attacking the e-pawn.

What do you recommend for White? This is not a single solution question. There is more than one good move.

Black had an excellent position from the opening but then did not take of his king

One would think that the offside Na3 would not be effective against the mighty bishop pair but looks can be deceiving
