Consider this auction:
| West | North | East | South |
| 1♥ | Pass | 2♣* | 2♦ |
| ? |
*Natural but forcing to game (2/1 style).
If you don't play 2/1 then imagine another GF auction, say:
| West | North | East | South |
| 2♣ | Pass | 2♥ | 2♠ |
| ? |
Do you do this?
| Action | Meaning |
| Pass | Either penalties or doesn't fit double |
| Double | Takeout/Support |
| Bid | Lots of shape |
This is what I call a backwards double. You have to pass when you want to double and double when you want to pass.
A takeout double asks partner to take action because you feel it is right but don't have a suitable bid yourself. Asking partner to bid in an auction that is already forcing makes little sense. I suggest the following system:
| Action | Meaning |
| Pass | Nothing to say |
| Double | I want to penalise |
| Bid | Suits or shape worth bidding |
