To understand actions immediately over their last bid in an aautcion that is ours, we can characterise hands as either clearly offensive, clearly defensive or not sure. With a clearly offensive hand, we will always make a bid, so the forcing pass and double need to cover the other two cases.

  • when the double is for penalty (as is always the case in a fit auction), that represents the clearly defensive hand; so the forcing pass shows an unsure hand
  • when the double is for takeout (usually the case in a disturbed auction), that represents a hand that is unsure of what the final outcome should be; so the forcing pass shows a clearly defensive hand
  • similarly, in a neutral auction, double will be some sort of replacement for another neutral bid, the bidder again unsure as yet as to where we are going; so the forcing pass shows the clearly defensive hand.

By breaking the 1NT barrier while unlimited, the 2 response made the auction ours. So East's pass is forcing and says something like 'assume (for the moment) that I am a flat 16-count with no fit for clubs; based on that, you must either bid or double for penalties'.

Double for penalties. It's not much of a hand, but you made the auction ours by bidding 2, and now partner has forced you to bid something.

A double in this position will often be made from weakness, and it is not all doom and gloom – as double would have been takeout, East's forcing pass shows a clearly defensive hand. With two clearly defensive hands and the balance of points, defending 2 doubled may well be the best option available.

Pass, forcing. The same hand, but with added action. Now double by you would be takeout, unsure of where to go, so your pass shows a clearly defensive hand.

This emphasises the point that 'clearly defensive' means soft, flat, points in short suits and low in playing strength relative to points. It does not necessarily mean a lot of points or a trump stack. One final example to emphasise this point:

Pass, forcing, and showing a clearly defensive hand, even though this hand may make no tricks in defence.
