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 "Sebesfi-Woods-1-Notrump-Escape."

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.
