This document provides an overview of randomization techniques for shuffling cards and discusses proper vs improper shuffling. It defines relative and absolute randomization and discusses how different shuffling techniques like riffling and piling affect the randomness of a deck. It also outlines signs that may indicate a player is not shuffling properly like orientation of the deck or eyes of the shuffler. Guidelines are provided for when and how to investigate potential improper shuffling or cheating during shuffling.
The document is an instruction manual for analyzing chess diagrams and identifying "impostors" - players pretending to be grandmasters. It provides context and diagrams for 12 cases, asking the reader to evaluate the position and determine which player is the impostor based on clues. For each case, it lists characteristics commonly seen in moves by impostors to aid analysis. The goal is to compare the reader's findings with those of the "Light Teal chess computer."
This document provides guidance on performing deck checks at competitive REL tournaments. It explains that the main purposes of deck checks are to deter cheating, catch any cheaters, and catch simple clerical mistakes in decklists. It outlines the steps of a deck check, including collecting the decks, checking the physical decks against the registered decklists, noting any issues found, and returning the decks with appropriate penalties if needed. Performing deck checks correctly helps ensure fair play at tournaments.

This document discusses common problems that occur at Friday Night Magic (FNM) tournaments and provides suggestions for addressing them. It identifies issues such as slow play, poor shuffling, damaged sleeves, inappropriate language, spectators advising players, drafting errors, no-shows, and lost items. The document emphasizes that FNM has a more relaxed atmosphere focused on fun and player education, and provides guidance for judges and organizers to help resolve problems and ensure players have a positive experience.
The document discusses different methods of shuffling cards, including pile shuffling, overhand shuffling, and riffle shuffling. It analyzes the effectiveness of each method at randomizing cards based on mathematical models. Pile shuffling is shown to not actually randomize cards. Overhand shuffling is a true randomization method but requires too many movements to be practical. Riffle shuffling is effective if done more than 1.5 log2(n) times, where n is the number of cards, making it the best practical shuffling method.

This document provides information about techniques for stacking a deck and cheating during shuffling in card games. It discusses common cheating methods like stacking a deck in a specific order, loading particular cards in certain spots, and forcing opponents to shuffle badly. It notes that players should be vigilant for tells that an opponent may be cheating during shuffling, such as excessive shuffling, watching how others shuffle, or using the same shuffling techniques each round. The document advises monitoring opponents closely who may be false shuffling and doing occasional deck checks to catch cheating.
How To Use Your Opponents' Aggression Against ThemRed Chip Poker
This document provides strategies for capitalizing on opponents' aggression and mistakes in poker games. It advises waiting for opportunities when opponents bet too frequently in predictable situations, such as continuation bets from out of position on dynamic flops that favor the player in position. Examples are given of calling bets on earlier streets and then raising on later streets to induce bluffs or thin value bets from opponents with capped ranges. The goal is to take advantage of opponents who fail to adjust their strategies and betting frequencies to current conditions.
This document discusses common misconceptions and myths among regular poker players. It argues that most regular players are at a "club level" and have no chance against elite players due to a wide skill gap. It debunks common "rules of thumb" like the five and ten rule and folding early to avoid getting outplayed, explaining how following such myths will prevent improvement. The document recommends doing range-building exercises daily to improve strategy and rise above the level of regular players.
The document provides guidance for judges on resolving issues that come up at Regular REL events, such as missed triggers, drawing extra cards, deck errors, and deviation from the JAR (Judging at Regular). It discusses common fixes, when deviation is acceptable, and presents scenarios for discussion, including a missed Jitte trigger, a player missing life gain, an end-of-combat misunderstanding, and an undeclared combat damage assignment. The goal is fair and fun gameplay balanced with customer service over strict adherence to policy.
Here are some adaptations that could be made to the game Knock Out:
- Use larger, softer balls that are easier to grip and throw for those with limited dexterity or strength. Foam balls would work well.
- Play seated so everyone can participate regardless of mobility. Players can throw from their chairs.
- Widen the target area by using a larger hula hoop or hanging a laundry basket on the wall.
- Allow multiple bounces before the ball needs to go in the target. This makes it easier.
- Have helpers pass balls back to players who miss rather than requiring them to retrieve their own ball.
- Keep score by counting made shots rather than eliminating players.
Chess is a game of strategy that develops critical thinking skills. It involves two players moving pieces on a board to trap their opponent's king through checkmate. While the basic rules are easy to learn, mastering chess takes a lifetime of practice as it challenges players with new situations in each game. Playing chess improves concentration, problem-solving, and the ability to learn from mistakes. It also teaches good sportsmanship and the value of experience over immediate results.
The document describes the development process of a board game called "Almost Horseshoes" which translates the mechanics of horseshoes into a card game. The designer iteratively prototyped and playtested versions of the game, refining rules and components until achieving a balanced gameplay experience that captures the strategic elements of horseshoes while being easy to learn and randomized. Feedback from playtesters showed that the final version provided opportunities for both offensive and defensive play styles while keeping rounds quick and the core concept clear.
This document discusses several potential situations that could occur during a game between two players and provides guidance on resolving conflicts. It notes there are 11 possible situations, including where the two players agree on a solution not supported by the game rules or where the players are in conflict. It also references rules for replacing or preventing effects and handling hidden card errors, advising players to call a judge if needed. The overall document aims to help players properly handle disputes or ambiguous situations through established rules and involving a referee when necessary.
This document provides guidelines for how to rule at a table as a judge. The key steps are to 1) approach with a smile while noting the time and squatting to their level, 2) listen separately to each player starting with the caller until fully understanding the situation, potentially defusing conflicts or calling a backup judge for clarity, 3) investigate whether a foul occurred requiring a head judge or deliver the ruling, and 4) deliver the ruling without strategic advice and offer an appeal while giving extra time and documenting the decision in writing.
The document discusses changes made to the penalty and remedy for the infraction of Drawing Extra Cards (DEC) in Magic: The Gathering.
It was previously considered a serious offense warranting a game loss. However, it has now been separated from other infractions and given a lesser penalty of a warning. The new remedy aims to negate any advantage without unduly punishing the player.
Specific examples are provided to illustrate how the remedy is applied in different situations, such as looking at too many cards or repeating an ability illegally. The focus is on finding the least disruptive solution while ensuring the opponent cannot know the identity of extra cards drawn.

The document discusses several scenarios in Magic: The Gathering and asks what could happen in each case. It asks about the maximum value for X in Chord of Calling with certain lands and a Wall of Roots on the battlefield. It also asks what would happen if a Fireball was cast for X=7 targeting a Phantasmal Abomination and opponent. Finally, it inquires about the converted mana cost of Gitaxian Probe if paid with Phyrexian mana by paying two life.

How to Manage Reception Report in Odoo 17Celine George
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

2. Small group session outline
• Quick overview of randomization techniques, and what it means for the state of the deck.
• Defining terms ‘Relative vs Absolute’ randomization.
• Effects of GSR (Riffle, Weave) shuffle on an ordered deck.
• Uncommon ‘Red Flag’ shuffling techniques.
• Investigations and Remedies.
• Demonstration of deceptive shuffling techniques.
• Discussion encouraged!
3. Discussion Goals
Equip judges with knowledge of shuffling techniques for:
• Teaching players new shuffling techniques who may be putting themselves at a disadvantage.
• Spotting and handling potential dishonest play.
• Curiosity
Additionally, group discussion about experiences with the subject, or subject content.
Shared learning is best learning.
4. Randomization techniques
RIFFLE, GSR
Pros:
Pseudo-Random fashion keeps relative order of cards difficult to keep track of
Fast technique, easy to repeat.
Cons:
Relative sequences of cards are kept intact, with each shuffle only providing one
break.
Bottom and Top cards in the deck typically experience very little variance, which
players can utilize to stack their presented decks.
PILE, WEAVE
Pros:
Allows a player to count their deck before presenting to opponent
Relative sequences are kept intact with an ordered pile shuffle, but introduces (n)
breaks per pile shuffle, where (n) is the number of piles.
Unordered pile shuffles potentially introduce greater variance.
Cons:
Slow technique, may be abused to run out the clock.
Player retains direct manipulation over each card, which players can utilize to stack
their presented decks.
5. Relative vs. Absolute
A standard singleton deck has 60! combinations. (Approximately the number of
atoms in the observable universe.) Even accounting for repetition, most standard
decks have at least 1049 permutations.
A random deck as most players define it is a deck where the order and positioning of
cards within the deck is not known. This is defined as ‘Relative’ randomization.
Standard shuffling by honest players will achieve this.
(Note: This level of randomization is sufficient for tournament play per the IPG
guidelines)
A truly random deck is a deck where each of the 1049 permutations is equally likely to
occur. Standard shuffling by players is likely insufficient to be close to this, although
with repeated shuffles, you can get sufficiently close.
It is possible for a player to achieve relative randomization, but put themselves at a
disadvantage by having a deck that maintains overall sequences.
6. Rule of 7 Cliffnotes
Persi Diaconis and Dave Bayer published “Trailing the Dovetail Shuffle to its Lair” in 1992, where he explores the variation distance between a known and random deck after (n)
riffle shuffles.
For a casino deck of 52 cards, Diaconis observes, using the Gilbert-Shannon-Reeds model of riffle shuffling, a sharp approach to total variation after the 7th shuffle.
Furthermore, he remarks that 3/2log2n shuffles are needed to mix (n) cards. For a 52 card deck, this equates to 8.55 shuffles. A 60 card deck would result in a value of 8.86.
Empirical Excel shuffling results suggest similar opening hands of land to non-land ratio between absolute-randomized decks, and sorted decks after 7 GSR riffle shuffles.
In 2004, Anke van Zuylen and Frans Schalekamp published “The Achilles Heel of the GSR-Shuffle”, where they evaluate the degree of randomness after (n) shuffles.
A game of ‘New Age Solitaire’, a perfectly played game using an absolute randomized deck has a 50% chance of winning. However, a sorted deck given 7 GSR riffle shuffles will
win 81% of the time. This is due to the nature of a GSR-riffle shuffle in such that it preserves relative sequences of cards, which is essential to winning that version of solitaire.

7. Normal Riffle
Deck is cradled in one hand.
Shuffling hand obscures bottom card.
Deck is positioned perpendicularly to eyes.
8. Dishonest Riffle (The Humphries shuffle)
Hands are positioned in a fashion to obscure
the deck from the opponents eyes.
Thumb is resting on bottom card of the deck.
Bottom of the deck is not held.
Deck is positioned such that bottom card is
easily revealed.
Topmost cards are kept constant.
9. Improper Shuffling vs. Cheating
As per the IPG (9/26/2014), section 3.4 –
Improper Shuffling
A deck is not shuffled if the judge believes a
player could know the position or distribution
of one or more cards in his or her deck.
Infraction – Warning
Remedy – Shuffle the deck thoroughly, taking
into account any parts of the deck ordered
through gameplay.
Examples when to use Improper Shuffling:
A player forgets to shuffle his library after
searching for a card.
A player searches for a card, then gives the
deck a single riffle-shuffle before presenting
the deck to her opponent.
A player fails to shuffle the portion of his deck
revealed during the resolution of a cascade
ability.
10. When to investigate?
When shuffling the deck of an opponent, there are unfortunately many methods of sleight of
hand. However, they all share one thing in common: The dishonest shuffler must know the
location of certain cards since the deck is foreign to them, and so they must look.
The two best indications that further investigation needs to take place are:
• The orientation of the deck
• The shuffler’s eyes
11. How to investigate?
For Cheating to be applicable, three criteria must be met:
• A player must break a rule
• A player must be attempting to gain an advantage by breaking the rule
• A player must be aware that what they are doing is illegal
Don’t alert the table until the shuffle is complete, and the decks are presented back to their
owners, much like a deck check, then interrupt. You can even interrupt the match under the
pretext of a deck check.
Gather the deck and investigate the stacked cards.
If, based on your observations, you believe a player has committed a cheating infraction, get the
head judge involved!
