Rubinsohl



To be more precise: this is a modified Rubinsohl, a somewhat simplified  version. (With more similarity with Sheinwold's Grubinsohl). Simplified as we do only employ Rubinsohl bids 2NT.....3S and not any at the 2-level.

Rubinsohl is a system of transfers. Its serious advantage over Lebensohl is that the suit is immediately known to partner (in Lebensohl only the rebid after 2NT declares the suit - if the bidding gets that far or opponents permits it!). In the specific case of bidding 2NT - transfer to Clubs - partner may now show a different suit negating Clubs. See further on.
A  second advantage is it also generally gets the hand played in the right hand far more often.

We use T-O doubles with Rubinsohl. (Original Lebensohl advocates penalty doubles throughout, also so does Sheinwold). The debate of Take-out versus penalty oriented is still out! My view is more one for Take-out in match-point scoring but possibly penalty oriented is better  in  pairs scoring ( IMPS scoring). Our BetaAcol preference is for  our T-O Double to be penalty oriented specifically in the cases where opponents are vulnerable (the value of a 200 penalty!) --- and more T-O oriented if opponents are non-vulnerable when a 100 penalty could be bettered especially with suits capable of making 110+

 Rubinsohl basics:

When your on the attACK!


Rubinsohl is employed in the following 4 situations:

  1. Defending a 3 preempt or a weak 2 in in any position - (against 2 precision too if agreed)
  2. Defending opponents 1NT opening of any strength - just a better suit against a strong NT!
  3. When partner opens 1NT 12-14 and opponents interfere with double or suit bid
  4. When opponents make a weak jump overcall at the 2-level
Rubinsohl is not used in the following 2 situations:
  1. Over 3-level openings or jump overcalls - but OK over a 3 weak jump overcall or opening (3  only)
  2. In any Protective position

Over a weak 2 opening 

2NT:            Transfer to Clubs
3:              Transfer to Diamonds
3:              Transfer to Hearts
3:              Stayman - shows 4 Hearts - partner accepts with (3)-5 cards, else bids 3NT, possibly PASSes with  3 Hearts.

3:               Transfer to 3NT Of course with a solid spade guard!

Over a weak 2 opening

2:               Non-forcing. Usually 5+ however a good 4 card may be shown even with only moderate values (small opening) else use 3 also showing 4 Spades & better values
2NT:            Transfer to Clubs. Any suit continuation shows invitational values & a Heart guard.
3:              Transfer to Diamonds
3:              Stayman - shows 4 card spade suit
3:              Transfer to Spades

Over a weak 2 opening

*                     T-O
2:                 Non-forcing - moderate values
2:                 Non-forcing - moderate values
2NT:               Transfer to Clubs. 2NT bidder may now continue with 3D's, H's, 3S's: Invitational with a Diamond guard, Clubs now unknown or 3NT to play
3:                 Stayman
3:                 Transfer to Hearts, 5+ card suit with better values or more length
3:                 Transfer to Spades, 5+ card suit with better values or more length

3:                 Transfer to 3NT

Over 1NT: 8+ and with 6 card suit

2NT:              Transfer to Clubs

3:                Transfer to Diamonds
3:                Transfer to Hearts
3:                Transfer to Spades
3:                Transfer to 3NT

or T-O * with 13+

or our CDH at the 2-level. (Classical Rubinsohl bids of 2 of a suit are not used)

When opponent Doubles partner's 1NT opening

See  2, 2 are better minor, while ** shows equal length in minors - partner to select his longer minor -,  2 Both majors, & 2 Natural 5+ card.

2NT:              Transfer to Clubs. All suit continuation are invitational.
3:                Transfer to Diamonds
3:                Transfer to Hearts
3:                Transfer to Spades

3:                Transfer to 3NT

If you rebid 3  after 2N-3: they shows invitational strength & 3NT is to play

When opponent Overcalls partner's 1NT opening with a real suit or implied suit at the 2-level:

Any new 2-level suit bids are Natural

2 of implied suit is Stayman - seeking 4 card majors

2NT:              Transfer to Clubs. Any suit continuation is invitationl and a guard in opponents minor suit or implied Major is also held
3:                Transfer to Diamonds
3:                Transfer to Hearts
3:               Transfer to Spades

If the transfer is to opponents implied suit. It becomes a stayman asking about unimplied  Majors with the exception of a Club intervention

If you rebid 3  after 2N-3: it shows: a guard in opponents real suit, invitational strength & 3NT, also with guard,  is to play.

Summary: All our 2-level bids are CDH or natural while 2NT & above follow Rubinsohl with extensions a la Sheinwold.
