SWINE is a bidding method after your side has opened or overcalled 1NT (natural) and the opponents have doubled for penalty. It's an acronym for "S
After the opposing double, the SWINE bids are:
|Pass || Requires partner to make an artificial redouble. Shows either a good hand that wants to play 1NT redoubled, OR any "touching" 2 suits (4-4 or better). After partner's redouble:
- Pass shows a desire to play 1NT redoubled.
- 2 shows clubs and diamonds.
- 2 shows diamonds and hearts.
- 2 shows hearts and spades.
- 2 not used.
|XX || Requires partner to bid an artificial 2 relay. Shows a weak one-suited hand (5+ cards). With clubs, simply pass partner's 2 bid; otherwise, bid naturally at the 2-level. |
|2 || Shows clubs and a major (at least 4-4). Partner can pass with club tolerance, or bid 2 to ask for the major suit. |
|2 || Shows diamonds and spades (at least 4-4). Partner can pass with 3+ diamonds or correct to 2 with longer spades. |
|2 || Shows 5+ hearts and constructive values (better than redoubling and then bidding 2). Non-forcing. |
|2 || Shows 5+ spades and constructive values (better than redoubling and then bidding 2). Non-forcing. |
|2NT|| Shows a strong and unbalanced hand, at least 5-5 shape in any two suits. Game-forcing.|
SWINE was created in 1973 by Australians Bob Sebesfi and Paul Woods.
