Attack Where the Bad Bishop Cannot Help!

Good day, chess world!

This is game 13 of Capablanca's My Chess Career, an exhibition game in Buenos Aires in 1911

This game will show you what is a bdad bishop and how to play against a bad bishop.
It is a great example on the theme of a bad bishop. No the bishop was not ill disciplined ! We use the term bad to describe the bishop as limited. Limited by what ?
That is the key to defining a bad bishop, we say a bishop is bad when its own pawns are fixed on the same color squares in the center as the bishop.

Rolando Illa's pawns settle on d5 and e6, light squares, which buries his light-squared bishop behind them. Capablanca plays a4 to stop that bishop escaping via b5, and it drifts to a8, where it spends the rest of the game looking at its own pawn. A piece that cannot reach the fight is not a piece. So Capablanca attacks the king, where he is effectively a piece up and the game ends eight moves later.
So the principle is When playing against the opponents bad piece : PLAY WHERE YOUR OPPONENTS BAD PIECE CaNNOT GET TO!

Four exercises from the game

Try to solve each before you watch. Capablanca is White here and he wins, so every exercise asks for White's move. All four come from the final attack, which the engine likes from the first move to the last. The answers are in the full game at the bottom, in the video, and in the website lesson linked below.

Exercise 1. White to play (move 20). Black's bishop is stuck on c6 behind d5 and e6, and his queen has just stepped back to d8. Which knight move starts the attack on the side where he has no defenders?

Exercise 2. White to play (move 22). Both knights are aimed at the kingside and the bishop on a8 is a spectator. Which capture tears open the shelter in front of the black king?

Exercise 3. White to play (move 24). Your knight sits on h6 and the king has walked to g7. Material is not the point now. Which capture keeps the king in the net?

Exercise 4. White to play (move 26). Black has just taken a knight on g5 and thinks he is surviving. Which check finishes it?
