Twisted SWINE is a bidding method after your side has opened 1NT and the opponents double for penalty. It's a variant of the SWINE convention. The differences from SWINE are shown below in bold.

PartnerOpp 1YouOpp 2

PartnerOpp 1YouOpp 2

After the opposing double, the Twisted SWINE bids are:

Bid Meaning
Pass  Requires partner to make an artificial redouble. Shows either a good hand that wants to play 1NT redoubled, OR diamonds and a black suit (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 spades.
  • 2 not used.
  • 2 not used.
XX Requires partner to bid an artificial 2 relay. Shows a weak one-suited hand (5+ cards) OR a game-forcing one-suiter (rare).
  • Weak one suiter: With clubs, simply pass partner's 2 bid; otherwise, bid naturally at the 2-level.
  • Game-forcing one suiter: Bid naturally at the 3-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 hearts (at least 4-4). Partner can pass with 3+ diamonds or correct to 2 with longer hearts.

2 Shows hearts and spades (at least 4-4). Partner can pass with heart tolerance or correct to 2.

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.

3-suit Preemptive, presumably a good 6+ card suit or longer. Note this agreement can be tacked onto practically any escape system.


Twisted SWINE was created by American player Jeff Goldsmith. Jeff's site has been on the Internet for many years. For his explanation of the convention, check out his Twisted SWINE page.
