Passed Hand Response
For example, a simple raise of an opening bid means the same whether responder is a passed hand or not, So after a 1 When responder has 3 Hearts and 10+ points, he can bid 1 When responder has bid 1 Also see The Drury Convention for responding to an opening 1-of-a-major when you are a passed hand. Most entries in the database can be used whether responder is a passed hand or not. Bids for which the specs are different for passed and unpassed hands need separate entries for each. For example, a Jacoby 2N response to 1 of a major shows 13+ HCPs if made by an unpassed hand, but shows a balanced hand with 11-12 HCPs if made by a passed hand. Likewise, a 2/1 response to an opening bid is game forcing when playing 2/1 Forcing. In BidBase's database, 2/1 Forcing entries have a Bid Order Number ("BON") starting with 1TF. Conventions which take precedence over 2/1 have smaller BONs. For example, Splinters start with 10Sp Bergen starts with 1B, Drury starts with 1Dru, etc. Standard entries (i.e.: not conventions) all have 6-digit BONs starting with 9, thus if 2/1 Forcing is deactivated, nearly all non-conventional responses to one of a major will have a BON starting with 9. One requirement for a bid to be 2/1 Forcing is that the bidder must an unpassed hand, so each 2/1 Forcing entry has that Position entered. Again, in BidBase nearly all non-conventional bids come after conventional bids, so if 2/1 Forcing is activated, then they will be tried before standard 2/1 bids ( BONs starting with 9) and if 2/1 Forcing is deactivated, they they will be skipped an stanard 2/1 bids will be tried.
