I have a question about the following strong club sequence:
IMPS, all vuln
1♣- (pass) - 1♦- (1♠)
pass-pass- ?
If I am correct, opener's pass shows he is ready to make a penalty pass if pard reopens with a double.
If this is true, my questions then become:
1) How strong must opener be to make a trap pass ? What are the requirements in terms of HCP and length in the overcaller suit ?
e.g.♠AKxx♥Kxx♦QJxx♣Axx
Does this hand meet the requirements ? Or is bidding 1NT safer?
2) Assuming opener's pass is a trap pass, is pard obliged to reopen at any cost, either by double or bidding anything, even holding a yarborough ?
E.g., after the above sequence, what do you bid holding
Hand 1
♠xxxx♥x♦xxxx♣xxxx
Hand 2
♠x♥xxxx♦xxxx♣xxxx
