1 - 2(weak jump overcall)-2 (a 100% forcing bid).
The opener - holding 4 good spades and above minimum jumped to game in 4
on many tables. Game had no chance. The 2 spade bidder held 7 hcps and 5 reasonable spades.
These are just 2 examples of getting the language wrong.
In the second instance you cannot make a 100% forcing bid with only 7hcps - your only choices are to make a negative double (which promises at least 4 spades) or to pass and wait for partner to reopen with a double.
Here are some other auctions which highlight common bidding problems.
This is an auction from 2 weeks ago. On 10 tables the auctions goes :-
In standard bidding, this auction shows game invite values and usually 6 hearts or 5 good hearts. 5 tables passed this bid. 5 bid 3nt. The opener had 2 little hearts and a 12hcp mnimum opener. The 3 heart bidder had 15 hcp and 5 hearts. So here a bid that is invite only gets passed - and what was needed was a 100% game forcing bid.
Here's another auction that caused problems
1
-P-1
-P
1nt-P-2
Here responder is trying to sign off - they are trying to make a strongly discouraging drop dead bid - a bid that in this auction should always be passed - both partners have limited their hands. This auction happened on 15 tables in the under 50 room and on 5 tables the opener with a minimum and 3 little spades bid 3 spades. 3 spades had no chances.
These are all examples where both partners are not speaking the same language.
The main components of that language are that opener can make bids that are:
Game forcing
Forcing for 1 round
Inviting game
Not forcing
An attempt to sign off / limit the openers hand
Responder can make bids that are:
Game forcing
Forcing for 1 eound
Inviting game
Not forcing
An attempt to sign off / strongly discouraging - limit responders hand
Drop dead
Now if both parners are speaking the same langauge and know when bids are forcing they don't have to jump to high too quickly for fear of being passed or they don't get too high raising partners strongly discouraging bids without the values to do so because they've missed games in the past.
What I thought I would try to do was to write up in a series over a few weeks how the 'language of bidding' gets defined and a set of genral principles we can use to try to tell when bids are forcing, game forcing, invite, drop dead and so on.
I'll do this in a number of parts...maybe one part a week. I'd be interested in any feedback about whether doing this is worthwhile. If not I'll drop the idea (sorry Morgann).
