Against Opening 3 answers

       Partners must pass, if in danger of having only two winners, as well as if in a state of danger not only had three winners, but if the partner has more than what is required, then the partner must raise pre-emtive this bid.

       For example, to bid pre-emtive 3C, in a dangerous state of responders had 4 winners, while opener only expect 2 winner, so there is still excess 4-2 = 2 winner, therefore, raise the opener to bid five clubs.

In the opener's hand there are 9-2 = 7 winner, responders had 4 winners, all of them a total of 11 winners, enough to bid at the 5.

       Winner or playing a card trick is not to be defeated by an opponent, for example AKQJ1098, the composition has a case of cards 7 winner, winner easy to calculate if a series of cards, but it is rather difficult if not a series or sequence cards from Ace to bottom.

Winner can be calculated from the fee - card

example:

AKQJ = 4 winner       AKJ   =  2 ½ winner

AKQ  = 3 winner        AQ10 = 2 winner

KQJ   = 2 winner        QJ      = ½ winner

QJ10  = 1 winner        AJ10  = 1 ½ winner

Winner of the card counted length / long suit:
Trump card which is more than 3 cards if supported partner count 1 winner
If you do not have the support of partners is calculated ½ winner
Trump Card is not / side suit
4 ½ count card winner
5 calculated a card winner
