The first jigsaw puzzles were referred to as push-fit puzzles and were simple and didn’t interlock. The purchase price of puzzles reduced because machinery developed and they could be manufactured more easliy.

Opening The Bidding At Bridge

Each game of Acol bridge starts with bidding. During the bidding, the partner’s send each other coded messages about their hand in the form of ‘bids’.

Each time someone makes a bid they are telling their partner something about their hand. The information given will include one or more of the following: a) Number of Points b) Suits held c) Shape of the hand.

The bidding is sometimes called the auction. As a result of the bidding the players decide on their target (known as the ‘Contract’) number of tricks and whether or not to use trumps.

The bidding starts with the dealer. Each player adds up the number of points in their hand. Count 4 points for each ace, 3 points for each king, 2 points for each queen and one for each jack.

If a player holds less than 12 points they say ‘PASS’. This continues clockwise round the table until the first person with 12 or more points makes a bid. This player becomes the OPENER. His bid is the OPENING BID and his partner is called the RESPONDER.

Bidding starts with one club, one diamond, one heart, one space and one No Trump (NT). A bid of one means that you believe you can win 7 tricks (the first six tricks are not scored).

An opening bid of one of a suit (clubs, diamonds, hearts or spades) means: ” I have 12 or more points and at least 4 cards in the suit I bid” An opening bid of 1NT means: ” I have 12-14 points and a balanced hand”.

A balanced hand contains cards in every suit (no voids), has no singleton (one card in a suit) and can have only one doubleton (two cards in a suit).

For example, four spades, 3 hearts, 3 diamonds and 3 clubs is a balanced hand. 3 spades, 4 hearts, 2 diamonds and 4 clubs is also a balanced hand (it only contains one doubleton). However, 4 spades, 5 hearts, 2 diamonds and 2 clubs is NOT a balanced hand – it has two doubletons (in diamonds and clubs).

In summary – you open the bidding if you have 12 or more points. Open with one of a suit if you have at least four cards in that suit. Open with 1NT if you have 12-14 points AND a balanced hand.

Learn To Backup Wii Games

If you got to read this article, it probably means that you have one Nintendo Wii game console. And it is very probable that you have found this article because you need some information on how to backup your Wii games.

A good reason to do that would be to preserve the original disk and play using the backups. In this way you can store away quite safely the originals. This article will give you some clues on how to do a backup for your Wii games.

First of all, you need to have the Nintendo Wii copying software. This software is reading your game from the original disk and then transfers it. The transfer is made into the ISO format. Normally, this is presented in a DVD format but sometimes a backup can go on a CD too.

The next thing you have to do is to put the Wii game right into the DVD drive and let it be read. After the Wii disk has been put inside you will have to launch the software. It will then transfer all the data on your PC. The transfer speed depends on the CPU speed of your computer and also on the memory of your PC.

For slower PC’s, this procedure can take even 4 hours. While the file is copied, the PC may appear frozen. Don’t worry about that and do not turn off the software or even the PC. If you do that, you will need to re-start the process again. When the transfer is done, you will have a new ISO file on the PC.

After the files were transferred on the PC, you can do the other step.

But you must change some software settings so that it sees the ISO file. Only after that you are able to burn the data on the blank media. After changing the setting, you need to insert your blank disk and start again the software. This burning process shouldn’t take long. It depends on the speed of the CPU unit and also on the memory on your PC.
