What is an adjective for an action that was performed well under pressure?

I've heard the word "clutch" used with this meaning (eg: "That was clutch!"), but is there a more sophisticated or well-codified word for such?

Example: "That was [adjective] when you answered the question correctly after the teacher so rudely shook you awake."

Solution 1:

Clutch, is a term popularized by gaming. In a match with other players, if you were the last player standing against a team of 4, and you managed against all odds to win the game, you would consider that a "clutch". Various uses of this word like, "That was clutch" are kind of incorrect because you would be more accurate to say that "it was a clutch".

However with slang like this there are no real rules. As for a sophisticated version of.

Meaning: Winning under pressure against overwhelming odds.

Where the opposite would be to "Choke".

I cannot find any word that is a more sophisticated way to refer to this extremely specific instance. I suspect that is why the word now exists in this context.

Supervene might be the closest word i could come up with but it doesn't quite describe the same scenario.
