Vuln vs NV,
Matchpoints Pairs,
you hold
QJ9xx-AQ-AKQJ-Jx
RHO (sorry I had mistakenly written "LHO") deals and opens... 1♠
1. do you trap pass or bid your hand as it were a (semibalanced) 18-20 (e.g. dbl +NT) ? Or anything else...
2. Would your choice depend on the vulnerability and on the form of scoring ?
Thanks !!
