Static Bid vs Dynamic Bid: Essence of Bidding System

Static Bid vs Dynamic Bid: Essence of Bidding System

Bidding is about communication. One person tell the partner (and the opponent) about what kind of of hand he/she is holding. The partner then respond back with either further inquiry or also describe his/her holding. This is the essence of any bidding system. But not too many bridge player really realize that those 2 activities (making asking bid and describing hand) are in fact the one make a bidding a static bid or a dynamic one. Understanding of this basic will lead to much better partnership, guaranteed !

Live Example

[Static Bid vs Dynamic Bid]

Static Bid vs Dynamic Bid

This example is probably very familiar.

Partner open first hand – all vulnerable – with 2 – weak 6-11hcp with 6 card. RHO (Right Hand Opponent) overcall 2. With 3 card support, 4-3-1-5, 5hcp, you know that most likely opponent have a game in minor or Spade. Then just to make them more difficult finding a fit in minor, you bid 3. LHO (Left Hand Opponent) double as responsive (no fit in spade) 8-10hcp.

Partner RHO You LHO
2 2 3 Double

Until this point everything looks quite good, LHO did not have Spade , so opponent could play 4minor with 4-3 fit in minor (if RHO have 2nd suit 5-1-4-3) or even 6-1 in Spade (6-1-3-3) and 3NT is unlikely. So, with hcp for a game is in their hand.

BUT SUDDENLY PARTNER BID 4!! RHO having 5-3-3-2 with only Ace heart as stopper is saved by your own partner, he just need to double. 4 Doubled 6 tricks for opponent: -800.  If partner did not bid probably it’s just -140 or even +50.

Partner RHO You LHO
2 2 3 Double
4??? Double!! All Pass

Who to blame ? Probably not entirely your partner. The question is whether or not you both understand first the different between Static Bid and Dynamic Bid.

Static Bid

Static Bid is a bid that almost completely describe your hand to a certain degree that partner will have enough information to determine the final contract. Once you bid a static bid, you can only bid again if:

  1. Partner makes asking bid as describe in your convention card. (Asking distribution, asking minimum or maximum point, etc)
  2. You can defeat opponent contract based on the bidding: Double for penalty.

That’s it, for the rest of the situation, most of the time the partner of the static bidder will be the captain that determine the final contract and the level (unless the partner hand in back the captaincy for a preference)

And furthermore, since the distribution and range are not too wide – descriptive enough, then there will be no need to apply negative double or such. So, double from responder is usually penalty.

Example of Static Bid:

  • Open 1NT 16-18hcp, no 5card minor. Hence the distribution either 4-3-3-3, 4-4-3-2 or 5m-3-3-2.
  • Open 2H/2S as weak two, 6card H/S with 6-11hcp, no second suit. So the distribution is most likely 6-3-2-2, 6-3-3-1.
  • Take out double (the type that has 12-15hcp with 3 other cards of unbid suit)
  • Unusual 2NT jump to show 5-5+ minor weak.
  • All preemptive bid
  • etc

Dynamic Bid

Dynamic Bid is – on the other hand – a bid that need a dynamic interaction between you and partner to find the best fit and contract level for the hand. It usually have various level of strength and plenty of possible distribution. Rebid (or lack of one)  from opener is usually very crucial . Therefore, any disruption from opponent (overcall, takeout,etc) need additional helper such negative double and other conventional bid.

Example of Dynamic Bid:

  • Opening 1H/1S (standard): 5card H/S 12-21hcp.
  • Opening 1C/1D (standard): 3+card C/D 12-21hcp.
  • Opening 1C Precision – Strong 16+hcp
  • Opening 2C Strong
  • Opening 2D Multi (Weak Major or Strong 3 suiter or balance)
  • etc

Final Word

In summary, the difference between static bid and dynamic bid are:


Dynamic Bid Static Bid
Captaincy back and forth mostly responder
Point Range wide narrow
Possible Distribution unlimited very restrictive
Double over opponent’s overcall Negative Double Penalty Double

Remember: a “Pass” is also a bid. No need to rebid if there is no new information. Partner knows it already….
