A maximal double is a form of game try used in competitive auction. It applies to situations when:

  • we have found a fit;
  • the opponents have taken away the bid immediately below our 3-level suit.
  • the partner has not denied invitational values.

If it is in effect, the following double is a maximal double:

South West North East
1 1 2 2
3 X

Note that, if there is a space between the opponent's suit and 3 of our suit, maximal doubles are off and the space used is the general game try:

South West North East
1 2 2 3

In this case, X is for penalty, 3 is a game try, 3 is competitive.
