"If the bidder be the offender, he shall be set back the amount of his bid
[_i.e._ the amount shall be scored in his _minus_ column], each of the
opponents scoring as usual for any trick or tricks he may have made,
including any which, but for the revoke, would have fallen to him.
"If one of the opponents be the offender, the cards of the trick in which
the revoke occurred, and of any subsequent trick, shall be taken back by
their respective holders, and the hand played anew from that point. The
bidder and the opponent not in fault shall each score according to the
result of the play, but the offender can score nothing for that hand, and
shall further be set back 100 points."
If a player finds that he holds the Joker, two knaves of the same colour,
and any two other cards of the same suit as one of the knaves, he has four
tricks certain, by declaring the three-suit trumps, unless all the other
five trumps be in the same hand. Should he hold two more tricks in the side
suits, he will be quite justified in bidding six.
The chances of getting another trump, by taking in the "widow," are an
important element in arriving at sound decisions. The odds evidently vary
with the number of trumps already held by the player. {262} The following
figures should be carefully borne in mind:
If a player holds four trumps, it is 8 to 5 on his finding one more at
least in the "widow."
If he holds five trumps, the odds are only 7 to 6 in favour.
If he has six, he must not reckon on getting another, the odds being 6 to 5
_against_.
