How To Use A Black Jack Jack

By: Harper Whitefield
  • Jack White and Jack Black have made a song together at last. On Black Friday, Jack White’s Third Man Records released a limited-edition 7-inch vinyl featuring the two artists in their long.
  • The rules of blackjack are quite simple, which is a major reason for the game's enduring popularity. The object is to get a hand with a value as close to 21 as possible without going over. A hand that goes over 21 is a bust. The players at a blackjack table do not play against each other; they play against the dealer.
  • Blackjack is played with a conventional deck of 52 playing cards and suits don’t matter. 2 through 10 count at face value, i.e. A 2 counts as two, a 9 counts as nine. Face cards (J,Q,K) count as 10. Ace can count as a 1 or an 11 depending on which value helps the hand the most.

Blackjack is an extremely popular casino game, and one that offers lots of strategies and tips to help the player overcome the house edge; as much as possible anyway. Below, we've documented the Top 10 Blackjack Tips to help you improve your game.

Blackjack Tips #1: When To Hit

It's the Slap Jack! A favorite of security and officers for generations, this beavertail sap is made from a heavy-stitched piece of black leather, the secret to this self-defense weapon is a lead weight embedded within. The 2.5' width means that this blackjack will deliver quite a bit of pain to your target without breaking bones.

Use the following rules to determine when to Hit, according to your hand and the dealer's face up card.

-If the dealer's face up card is 7, 8, 9, 10 or Ace, and your hand totals 8 or 12 through 16, Hit.
-If the dealer's face up card is Ace, and your hand totals 11, do not Double, Hit.
-If the dealer's face up card is 10, and your hand totals 10, do not Double, Hit.
-If the dealer's face up card is 7, 8 or 9, and your hand totals 9, do not Double, Hit.

Blackjack Tips #2: When To Stand

Use the following rules to determine when to Stand, according to your hand and the dealer's face up card.

-When your hand totals 17 or above, no matter what, Stand. (Some strategies will tell you to hit 17 if the dealer has an Ace.)
-If the dealer's face up card is 6 or below, and your hand totals 13 or above, Stand.
-If you have a splitable pair of 10s or Face Cards, do not Split them, Stand.

Blackjack Tips #3: When To Split

Use the following rules to determine when to Split your hand, according to value of your pair and the dealer's face up card.

-Only Split 2s and 3s if the dealer's card is 4-7
-Never Split 5s; either Double Down, or Hit if the dealer is showing a 10 or Ace.
-Split 6s and 7s if the dealers card is 6 or below.
-Always split 8s, no matter what.
-Always Split Aces if allowed.

Blackjack Tips #4: When To Double

Doubling is a strategy often used when the player's hand equal 9, 10 or 11, giving the player a good chance of hitting 19-20 with a 10 or Face card. Use the following rules to determine when to Double your hand, according to your total and the dealer's face up card.

-Always double a total of 10 unless the dealer has 10 or Ace.
-Always double an 11 unless the dealer has an Ace.
-9 should only be doubled when the dealer has 3, 4, 5 or 6 showing.

Blackjack Tips #5: When in Doubt, Use a Strategy Chart

Blackjack Strategy Charts are designed to tell a player exactly how to act in every possible situation. Some players do not like blackjack Strategy Charts because they remove the element of decision making, but consider this... Casinos get the upper hand because the dealer cannot make decisions. The dealer must follow strict rules based on probabilities when playing their hand. If the player uses the same strategy, he is effectively decreasing the house edge to a minimum.

Blackjack Tips #6: Game Selection, Know The Rules

There are many more variations of Blackjack than the classic version we all know and love. Each has a slight difference in the rules, and some even have optional side bets and progressive jackpots. When choosing to play a new variation of blackjack, such as Perfect Pairs, Super 21 or Progressive Blackjack, be sure to know all of the rules and payouts involved.

Blackjack Tips #7: Card Counting

Blackjack Card Counting is an age-old strategy used by many professional blackjack players. It is not that hard to learn, and can be very effective in minimizing losses and maximizing profits. It is recommended to get a good deal of practice in card counting before applying the strategy at a live casino so that the extensive security staff does not discover you are doing it. Card counting is not illegal by any means, but it may get you promptly, if not permanently, removed from the casino if caught. Note that card counting is not a viable online casino blackjack strategy. Online casino software re-shuffles the deck with each new hand.

Blackjack Tips #8: Play Online, It's Cheaper

Aside from the omission of card counting, playing online blackjack has many benefits. For one, you can put all of the money you intended to spend towards your bankroll. You won't have to gas up the car, purchase airline tickets or book a hotel (if no local casino). When you win, you won't have the obligatory 'tipping the dealer' to reduce your profits. All in all, it just makes sense to stay home, eat your own food, drink your own drinks and spend a lot less money by playing blackjack online.

Blackjack Tips #9: Play Online for Bonuses

Playing online isn't just about convenience. You can actually double or triple your bankroll when you sign up at an online casino. They all offer welcome bonuses, most matching your first deposit 100% to 200% or more, up to a certain amount. Instead of starting with $100 bankroll, made up of your own hard earned cash, why not play online and claim a welcome bonus that could give you're a lot more bankroll for your buck by way of free casino chips?

Blackjack Tips #10: Bet Sizes That Match Your Bankroll

Lastly, we'll go ahead state the obvious. Don't play a blackjack table where the limits do not correspond with your bankroll. If you have $200, don't sit at a blackjack table with a minimum $100 bet. No matter how many blackjack tips and strategies you apply, you'll want to have plenty of opportunities to play hands, with splitting and doubling available, in order to make a sizeable profit. Make sure you will be able to place a minimum of 40 bets with your bankroll before choosing a table.

A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power.[1] The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). Industrial jacks can be rated for many tons of load.

Etymology[edit]

Jackscrews are integral to the scissor jack, one of the simplest kinds of car jack still used.
Threaded rod, 7 inches fully extended

The personal name Jack, which came into English usage around the thirteenth century as a nickname form of John, came in the sixteenth century to be used as a colloquial word for 'a man (of low status)' (much as in the modern usage 'jack of all trades, master of none'). From here, the word was 'applied to things which in some way take the place of a lad or man, or save human labour'. The first attestation in the Oxford English Dictionary of jack in the sense 'a machine, usually portable, for lifting heavy weights by force acting from below' is from 1679, referring to 'an Engine used for the removing and commodious placing of great Timber.'[2]

Jackscrew[edit]

Scissor Jack[edit]

Scissor car jacks usually use mechanical advantage to allow a human to lift a vehicle by manual force alone. The jack shown at the right is made for a modern vehicle and the notch fits into a jack-up point[3] on a unibody. Earlier versions have a platform to lift on a vehicle's frame or axle.

Electrically operated car scissor jacks are powered by 12 volt electricity supplied directly from the car's cigarette lighter receptacle. The electrical energy is used to power these car jacks to raise and lower automatically. Electric jacks require less effort from the motorist for operation.

House jack[edit]

A house jack, also called a screw jack, is a mechanical device primarily used to lift buildings from their foundations for repairs or relocation. A series of jacks is used and then wood cribbing temporarily supports the structure. This process is repeated until the desired height is reached. The house jack can be used for jacking carrying beams that have settled or for installing new structural beams. On the top of the jack is a cast iron circular pad that the jacking post rests on. This pad moves independently of the house jack so that it does not turn as the acme-threaded rod is turned with a metal rod. This piece tilts very slightly, but not enough to render the post dangerously out of plumb.

Hydraulic jack[edit]

The working principle of a hydraulic jack

In 1838 William Joseph Curtis filed a British patent for a hydraulic jack.[4]

In 1851, inventor Richard Dudgeon was granted a patent for a 'portable hydraulic press' - the hydraulic jack, a jack which proved to be vastly superior to the screw jacks in use at the time.[5]

Hydraulic jacks are typically used for shop work, rather than as an emergency jack to be carried with the vehicle. Use of jacks not designed for a specific vehicle requires more than the usual care in selecting ground conditions, the jacking point on a vehicle, and to ensure stability when the jack is extended. Hydraulic jacks are often used to lift elevators in low and medium rise buildings.

A hydraulic jack uses a liquid, which is incompressible, that is forced into a cylinder by a pump plunger. Oil is used since it is self lubricating and stable. When the plunger pulls back, it draws oil out of the reservoir through a suction check valve into the pump chamber. When the plunger moves forward, it pushes the oil through a discharge check valve into the cylinder. The suction valve ball is within the chamber and opens with each draw of the plunger. The discharge valve ball is outside the chamber and opens when the oil is pushed into the cylinder. At this point the suction ball within the chamber is forced shut and oil pressure builds in the cylinder.

Floor jack[edit]

In a floor jack (aka 'trolley jack') a horizontal piston pushes on the short end of a bellcrank, with the long arm providing the vertical motion to a lifting pad, kept horizontal with a horizontal linkage. Floor jacks usually include castors and wheels, allowing compensation for the arc taken by the lifting pad. This mechanism provides a low profile when collapsed, for easy maneuvering underneath the vehicle, while allowing considerable extension.

Bottle jack[edit]

A bottle jack or whiskey jack[6] is a jack which resembles a bottle in shape, having a cylindrical body and a neck. Within is a vertical lifting ram with a support pad of some kind fixed to the top. The jack may be hydraulic or work by screw action. In the hydraulic version, the hydraulic ram emerges from the body vertically by hydraulic pressure provided by a pump either on the baseplate or at a remote location via a pressure hose. With a single action piston the lift range is somewhat limited, so its use for lifting vehicles is limited to those with a relatively high clearance. For lifting structures such as houses the hydraulic interconnection of multiple vertical jacks through valves enables the even distribution of forces while enabling close control of the lift.

The screw version of the bottle jack works by turning a large nut running on the threaded vertical ram at the neck of the body. The nut has gear teeth, and is generally turned by a bevel gear spigotted to the body, the bevel gear being turned manually by a jack handle fitting into a square socket. The ram may have a second screwed ram within it, which doubles the lifting range telescopically.

Bottle jacks have a capacity of up to 50 tons and may be used to lift a variety of objects. Typical uses include the repair of automobiles and house foundations. Larger, heavy-duty models may be known as a barrel jack.[7]

This type of jack is best used for short vertical lifts.[8] Blocks may be used to repeat the operation when a greater amount of elevation is required.[9]

Pneumatic jack[edit]

Air hydraulic jack[edit]

An air hydraulic jack is a hydraulic jack that is actuated by compressed air - for example, air from a compressor - instead of human work. This eliminates the need for the user to actuate the hydraulic mechanism, saving effort and potentially increasing speed. Sometimes, such jacks are also able to be operated by the normal hydraulic actuation method, thereby retaining functionality, even if a source of compressed air is not available.

Inflatable jack[edit]

A demonstration of using two stacked air bags to lift the rear of the car

An inflatable jack, lifting bag, or pneumatic lifting bag is an air bag that is inflated by compressed air (without a hydraulic component) in order to lift objects. The bag can be deflated to be reused later. The objects can be of a smaller load such as an automobile[10] or it can be a larger object such as an airplane.[11]

Air bags are also used by rescuers to lift heavy objects up to help victims who are trapped under those objects. There are three main types of lifting bags for rescue: high pressure, medium pressure and low pressure systems. Low-pressure bags are operated at 7.25 psi for high vertical lift in a large surface area but lower lifting capacities. Medium-pressure bags are operated at 15 psi. High-pressure bags which have higher lifting capacities are operated at pressure between 90 and 145 psi. Two air bags can be stacked together to provide a higher lift. It is recommended that no more than two bags can be used in a stacked configuration, the bigger bag must be the bottom one, and no other objects are inserted between the stacked bags. Incorrect use of stacked bags may result in a bag (or other objects) shooting out to create a dangerous projectile.[12]

Strand jack[edit]

A strand jack is a specialized hydraulic jack that grips steel cables. Often used in concert, strand jacks can lift hundreds of tons and are used in engineering and construction.

Farm jack[edit]

The farm jack also known as a railroad jack, high lift jack or kanga-jack was invented in 1905. It consists of a steel beam with a series of equally spaced holes along its length, and a hand-operated mechanism which can be moved from one end of the beam to the other through the use of a pair of climbing pins. Typical sizes for the farm jack are 4 feet (1.2 m), 5 feet (1.5 m)and 6 feet (1.8 m) referring to the length of the beam.

The jack's versatility stems from its use for such applications as lifting, winching, clamping, pulling and pushing. It is this versatility, along with the long travel it offers and its relative portability, which make the farm jack so popular with off-road drivers.

Safety standards[edit]

National and international standards have been developed to standardize the safety and performance requirements for jacks and other lifting devices. Selection of the standard is an agreement between the purchaser and the manufacturer, and has some significance in the design of the jack. In the United States, ASME has developed the Safety Standard for Portable Automotive Service Equipment, last revised in 2014, including requirements for hydraulic hand jacks, transmission jacks, emergency tire changing jacks, service jacks, fork lift jacks, and other lifting devices.[13]
