one more chaotic post on my unclear ideas on bidding !!!
Reading Berkowicz's "Precision today", I recognized that, discussing one of the merits of <16 limited openings, he suggests that a raise 1M:4M can be left as undetermined: either a "pure" preemptive raise = 4-5 cards support and very few HCP, or a good raise that excludes slam, say some balanced 3 cards support and 13 HCP.
The advantage of such approach would be to leave opps in the dark, e.g. they do not know whether to double, bid or pass, since they ignore responder's strength.
This makes sense, but it also affects the use of forcing pass and doubling issues.
An example:
IMPS, none vuln,
you deal and open 1♥ 11-15 with
Qxx-KQTxx-AJx-Qx
1♥-pass-4♥-4♠
Now I guess I would like to double if pard held a balanced good raise, but not if pard has raised to 4♥ with something like:
void-Jxxx-Qxxxx-xxxx
Similarly, I guess that holding something like
x-KQTxx-AJxx-Qxx
I'd like to make a forcing pass.
--------------------------------------------------------------------------------------------
(Forgive me if I brought bad examples, in that case I will encourage corrections to the type of hands I chose for forcing pass/double sequences and suggestions for better examples)
--------------------------------------------------------------------------------------------
So I would like to hear opinion on the tactics of concealing the strength of a raise (preemptive vs good): on one hand you lose the forcing pass options, on the other hand you leave opps in the dark.
BBO Gurus, enlighten me !!!
