I am trying to define better and better strong club (16+) overcalled sequences, so here are 3 questions related to opps preempting at the 3 level.
In the version we play, 1NT opening = 10-12 bal , 13-15 bal are included in 1D opening, so the minimum strength for a balanced 1C is 16.
Thanks all !!

CASE 1
1♣-(3Y)- ?
I know double shopuld not be playted as penalty nor as simple "cardshowing".
However, I have see 2 different approaches:
1) negative double as takeout major-oriented
2) "thrump double" à la Bergen, stopper asking )especially useful when preempt is in spades)
Which one do you recommend ?
Also, what should a cuebid mean ?
----------------------
CASE 2
1♣-pass-1♦(0-7)- (3Y)
?
What should double be here ?

CASE 3
1♣-pass-positive suit response- (3Y)
?
"Positive response" here is 1H/s or 2C/D showing 5+ cards and 8+ hcp.
What should double be here ?
