Black finally frees the bishop but now his king will be in a pretty shaky situation.

Vladimir Kramnik Peter Leko Dortmund 2013 White to move
White's position is no doubt preferable, but there is only one move that wins the game for Kramnik at this moment. Can you see it?
The knight was well placed on c5, supporting the a4-push on the queenside. However, Black was planning ...Ke7, unpinning the knight and offering a rook trade next. With this knight maneuver, Kramnik looks for the e5-square and another weakness like g6 besides threatening Nb4. The knight invasion on e5 is devastating.
Black cannot move the knight since after the rook trade, the bishop on f7 is hanging.

Ian Nepomniachtchi Liren Ding World-ch 2023 White to move
Black has just played 31...Rb8 from a8, in order to avoid being captured with the e4-queen. This move looks inoffensive but Black has some ideas in mind. What is the best move for White here?
Fantastic prophylaxis from Nepo. White stops b4 by protecting the b2-pawn and now is ready to start the attack on the kingside.
32.g4 looks natural but allows Black counterplay after 32...b4! 33.Qc4 The point after 33.cxb4 is that the b2-pawn is hanging! 33...bxc3 and Black has decent chances of drawing the game since all the pawns on the queenside have disappeared.
