For some people the word "climax" has a technical sense when discussing a play. This might cause them to identify the climax with act 3 of any Shakespearean play. In a non-technical sense, the climax of the play comes when Othello smothers Desdemona. He had a chance up to that point but none after.
Act IV
Hamlet, Act 3 Scene 1

Shakespearean tragedies typically follow a five-act structure. Act 1 sets up the conflict, Act 2 develops it, Act 3 contains the climax, Act 4 shows the consequences of the climax, and Act 5 concludes the story with the resolution. Central themes often include the downfall of a tragic hero, fate, and the consequences of human flaws.
The acts in a Shakespearean play serve to structure the plot and provide a sense of progression. Each act typically represents a major development in the story, building tension and leading towards the climax. Acts help to organize the play into manageable segments for both the performers and the audience.
