Team match,
We are VULN, opps are Non-Vuln
RHO deals and opens 1C (better minor) and I am dealt:
Qx-KQJx-Axx-KQJx
If I were playing natural 1NT overcall, I might downgrade the hand to 17 (for ♠Qx) and overcall 1NT, but we play Raptor so I double.
LHO Redoubles and pard bids spades.
We did not discuss if her bidding spades should promise 4 or 5.
RHO passed and, being in doubt, I bid 1NT, which was doubled -2, a bad swing.
Summarizing the bidding:
RHO....me....LHO....pard
1C......X.......XX......1S
p........1NT....X.....all pass
Pard held:
xxxx-x-xxxx-xxxx
Questions:
1) Should 1S promise 5+ length in spades ?
I think so, and in that case I'd have passed.
2) I suppose that with the given hand, my pard should have passed, and we would have ended in 1NT X - 2 anyways ?
Or should there be a runout mechanism ? (e.g. scramble in the diamond moysian here)
