Whenever I’m insulted at the table, I remind myself that it is automatically a mistake by the person making a comment—because they are giving away a lot of free information. The most common insult I face is about how aggressive I am, such as “push bot donkey” or “hot Jenny you got any other moves??” Etc.
The thing is that these comments automatically indicate to me that the person doesn’t fundamentally understand tournament play and is extremely likely to be playing way too tightly. Whenever someone is critical of your play, unless it is someone that you respect a lot, focus on what their criticism says about how they play.
This info can be extremely profitable—such as when I get berated for making an any-two pot odds call, I make a note on that player that they will make pot odds mistakes, and as a result can shove wider on them with a short stack than I would versus an unknown opponent.
And it is easier not to get riled up from nasty comments when you take them for the statements of ignorance/free information that they actually are. When you use their insult to make more money from them, then you get the last laugh
