Vidit Gujrathi (2742) vs Nodirbek Abdusattorov (2727), Tata Steel Masters 2024, Round 12

Black has just played his bishop to the c4 square. How should White react?
The bishop seems to have settled on d3. How did Vidit (White) continue?
Perhaps the most important move of the game. White to play.
How does White tighten the noose here?
