Ogust
- After opener's weak 2 preemptive bid, a 2 Notrump Call by responder instructing opener to rebid
using a conventional step response describing the preemptive hand's suit quality and
overall strength. Some disciplined weak 2 openers use "binodal" opening
range, depending on vulnerability (the ACBL limits the range to 7 points). Also see
Convention Card Instructions, Feature
and books on
Preempts
Here are typical preemptive weak 2 opening bid ranges used by Ogust players:
Your Side |
Opponent |
Preemptive Weak 2
Opener Point Range |
Non-Vul |
Vul |
Less, as 3-9 |
Non-Vul |
Non-Vul |
Less, as 3-9 |
Vul |
Vul |
Perhaps 8-11
(some play less than 8) |
Vul |
Non-Vul |
More, as 8-11 |
Accordingly,
these ranges
will affect responder's "good or bad" response. 2D/H/S - 2N:
Response |
Meaning |
3C |
Bad overall
strength, bad suit quality |
3D |
Bad overall
strength, good suit quality |
3H |
Good overall
strength, bad suit quality |
3S |
Good overall
strength, good suit quality |
3N |
Solid trump suit = A K Q
x x x |
Note: A
good trump suit usually promises 2 of 3 top honors; some
players reverse the meaning between the 3D and 3H Calls (Harold Ogust's
original treatment).
Rather than increasing the level of opener's preempt, some crafty Responders
use a 2N response with negligible values. Particularly when opener's
suit is Spades, this "Dump Ogust" tactic sometimes confuses the opponents'
(especially the advancer) into thinking
responder holds invitational values. Of course, if partnership have an explicit
understanding of this method the bid is alertable.
Many play a new suit bid by responder is forcing one round (i.e., RONF -
Raise Only Non Forcing) while others play responder's new suit in merely
invitational. If an opponent interferes after opener's preemptive
bid, responder's new suit bid is not forcing.
Alternatively,
some players incorporate one features from the McCabe Adjunct - see
Details (alertable).
Playing the McCabe feature when Right Hand Opponent makes a double over
partner's weak 2 opener:
2D - (X) - 2H;
1. |
A direct raise of opener's
suit is competitive, usually showing an honor (Diamonds here) |
2. |
A bid in a new suit is lead
directing (Hearts here), also showing competitive length in opener's
suit without honor strength. |
Wise
partnerships also have bidding understandings when opponents interfere before or
after responder's 2N Ogust call. For instance, after 2N
some play Ogust "systems on" including the "stole my bid" Double, while
others use a DOPI or DOP1 mechanism. |
