Misère

Misère is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Misère rather than just read about it. In short: Misère (French for "destitution"), misere, nullo, bettel, betl, beddl or bettler (German for "beggar"; equivalent terms in other languages include Spanish: contrabola, pobre, and Italian: devole) is a bid in various card games, and the player who bids misère undertakes to win no tricks or as few as possible, usually at no trump, in the round to be played. This does not allow sufficient variety to constitute a game i…

Key takeaways

Misère belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Misère to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Misère from memory before moving on to harder problems.

Reference excerpt

Misère (French for "destitution"), misere, nullo, bettel, betl, beddl or bettler (German for "beggar"; equivalent terms in other languages include Spanish: contrabola, pobre, and Italian: devole) is a bid in various card games, and the player who bids misère undertakes to win no tricks or as few as possible, usually at no trump, in the round to be played. This does not allow sufficient variety to constitute a game in its own right, but it is the basis of such trick-avoidance games as Hearts, and provides an optional contract for most games involving an auction. The term or category may also be used for some card game of its own with the same aim, like Black Peter. A misère bid usually indicates an extremely poor hand, hence the name. An open or lay down misère, or misère ouvert is a 500 bid where the player is so sure of losing every trick that they undertake to do so with their cards placed face-up on the table. Consequently, 'lay down misère' is Australian gambling slang for a predicted easy victory. In Skat, the bidding can result in a null game, where the bidder wins only if they lose every trick. (Conversely, the opponents win by forcing the bidder to take a trick.) In Swedish Whist, by contrast, a null game is one in which both teams try to take the fewest tricks. This variation is known as ramsch in Skat. In Spades, bidding for no tricks is known as bidding nil, which if successful gives the bidder a bonus. The word is first recorded in this sense in the rules for the game "Boston" in the late 18th century. It cannot be played in 6 hand 500.

Misère game A misère game or bettel game is a game that is played according to its conventional rules, except that it is "played to lose"; that is, the winner is the one who loses according to the normal game rules. Or, if the game is for more than two players, the one who wins according to the normal game rules loses. Such games generally have rulesets that normally encourage players to win; for example, most variations of checkers (draughts) require players to make a capture move if it is available; thus, in the misère variation, players can force their opponents to take numerous checkers through intentionally "poor" play (see poddavki). In combinatorial game theory, a misère game is one played according to the "misère play condition"; that is, a player unable to move wins. (This is in contrast to the "normal play condition" in which a player unable to move loses.) Examples of games that use the misère play condition include Sylver coinage.

Worked examples

Example 1 — a first encounter with Misère

Start with the simplest possible case. Write down what Misère claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Misère before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Misère ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Misère

In research: Misère appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Misère in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Misère is common in secondary-school and first-year university syllabi. It links to neighbouring topics Board game terminology, Card game terminology, Combinatorial game theory, so understanding it makes those chapters shorter.
In everyday life: Look for Misère outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Misère in simple terms?

Why does Misère matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Misère?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
