Je fais un bluff, quitte à perdre la manche.

French often uses faire + noun for actions, and that pattern can feel very natural.

So faire un bluff means something like to make a bluff / to bluff.

A learner should also know that bluffer exists as a verb, so je bluffe is possible too. In fact, depending on context, je bluffe or je tente un bluff may sound more idiomatic than je fais un bluff.

So the sentence is understandable, but it is useful to recognize that French may express the same idea in more than one way:

• je fais un bluff
• je tente un bluff
• je bluffe

Quitte à is a fixed expression meaning:

• even if it means
• at the risk of
• if necessary, even at the cost of

So quitte à perdre la manche means the speaker is willing to accept that consequence.

The idea is: I’m bluffing, even if it means losing the round.

It suggests a conscious risk, not just a neutral possibility.

Because quitte à + infinitive is the standard structure.

You should learn it as a set expression:

• quitte à attendre = even if it means waiting
• quitte à échouer = even if it means failing
• quitte à perdre la manche = even if it means losing the round

So this is not a case where you should try to translate quitte word for word. In this construction, the whole expression quitte à carries the meaning.

Because after quitte à, French uses the infinitive.

So:

• quitte à perdre
• not quitte à je perds

This is similar to how English says even if it means losing, not even if it means I lose in the same structure.

Yes, la manche often means sleeve, but it also has a game-related meaning: round or stage of a game/match.

So in this sentence, la manche is not about clothing. It refers to part of a game.

That kind of double meaning is common in French:

• une manche de chemise = a shirt sleeve
• la première manche = the first round

Context tells you which meaning is intended.

Because in French, bluff is treated as a masculine noun, so it takes un:

• un bluff
• not une bluff

Many borrowed nouns in French are assigned a grammatical gender, and this one is masculine.

It is understandable, especially in a game context, but some native speakers might more naturally say:

• Je bluffe, quitte à perdre la manche.
• Je tente un bluff, quitte à perdre la manche.

So je fais un bluff is not impossible, but it may sound a little less idiomatic than those alternatives.

For a learner, the most important thing is to understand:

• the action: bluffing
• the accepted risk: quitte à perdre la manche

The comma separates the main action from the risk or consequence that follows.

• Je fais un bluff = the main action
• quitte à perdre la manche = the consequence the speaker accepts

The comma helps readability and makes the sentence sound more natural. It marks a slight pause, like: I’m bluffing, even if it means losing the round.

Yes, it is used much more widely than just games.

For example:

• Je vais lui dire la vérité, quitte à le vexer.
  = I’m going to tell him the truth, even if it upsets him.
• Elle a déménagé, quitte à recommencer de zéro.
  = She moved away, even if it meant starting from scratch.
• Il a pris ce risque, quitte à tout perdre.
  = He took that risk, even at the cost of losing everything.

So in your sentence, quitte à perdre la manche is one example of a very useful general pattern.

Usually not if you mean round.

In game vocabulary:

• la manche often means round or stage
• la main often means hand, especially a hand of cards, or sometimes whose turn/control it is

So the best choice depends on the exact game situation.

For example:

• perdre la manche = lose the round
• perdre la main = lose the hand / lose the lead / lose control, depending on context

That is why context matters a lot with game words in French.
