1H/1S opening without interference

1. Open 1H/1S

 

1.1.       Responses to 1H/1S without interference

(10)11-15 HCP always at least a 5 card suit. Jump-shifts by opener show a good 13 to 15 HCP. 10-16 HCP in 3rd seat could be light and 12-16 HCP in 4th. Hands with, 5M332 and 15 HCP are often downgraded as a bad 15 and opened 1M or 1N if possible in 1st or 2nd seat.

There is a gap in the hands for responder, namely 14-17 HCP, 4 trump plus a singleton. It is perhaps too strong to splinter and there will be some hands not suitable for a strong jump shift. I propose for these hands you stretch and make a jump shift where possible.
 
After 1M-2M the following raises are used:
            A new suit is a help suit game try
            2N ask responder to bid game with a maximum
            3M asks responder to bid game with good trump
This is also used after 1M-1N-2X-2M and 1-1M-2M.
 
Opener's rebids after a 2N response:
  1. Rebids own suit with 6 or more
  2. Jumps to 4 in own suit if suit headed by AKQ
  3. Bids 3N with 5-3-3-2 distribution
  4. Bids a 4 card suit(including Spades over Hearts)
  5. Jump to 4 level in new suit with 5-5 or better
Responder can bid the next step (skipping 4 of the major and 3N if necessary) to inquire about opener's strength
            First step: Minimum 10-12 HCP. Second step: Maximum 13-14 HCP
 
New Minor Forcing over sequence 1-1♠-1N-2♣
2: 10-12 HCP denies 3 Spades
2: 13 HCP denies 3 Spades
2♠: 10-13 HCP 3 Spades
2N: 14-15 HCP neither confirms nor denies 3 Spades, 3♣ now asks for 3 Spades
 
Over 1-1N-2♠ we play Lebensohl.

1.1.2.  Responses to 1H/1S in 3rd seat

In 3rd seat only we may open light. New suits are not forcing so should generally make a raise or use Reverse Drury, if applicable. 1N is forcing, passing with a balanced minimum and a 2 Major rebid by opener still could be light. The normal range of values for a third seat opening is 10-16(17) HCP with the maximum being raised by 2 HCP.

            3M:  11+ supporting hand
      2 (over 1): 4 hearts looking for 4-4 fit without a full opener
      2M: less than a minimum opener (in 4th seat: a minimum opening which would refuse a limit raise)
      higher bids have regular meaning but will usually just bid 4M with no slam interest

1.1.3.  Responses to 1H/1S in 4th seat

In 4th seat we do not open light, with bids basically the same meaning as in 3rd seat using Reverse Drury. The range for fourth seat openings is 12-16 HCP and not opening hands with 5M332 distribution and only 12 HCP. The bids with different meaning are 1♠ which is still forcing and the negative response to Drury shows a minimum opening not a sub-minimum. We have mini-splinters with (11)12+ pts.  3♣ is still a natural constructive INV. New suits(except for 1♠) are non-forcing, so a new suit denies support for opener. 1N is forcing.
