Inferences
- 5-card preempts are sane with a good suit.
- Raising on Qx is somewhat insane with those spades unless with.
- If RHO has a stiff club, I doubt that I can make for lack of cashing side tricks in the "crossruff line" (6 spades, 0 hearts, 2 diamonds, 1 club) and lack of running suit in the "draw trumps line" (cannot ruff because that would lose SA, HA, two natural spade tricks).
Therefore, using the "bid and pray" system, I pray that RHO is ...
5332 Because you implied it may be makable
Assuming the latter, I'm going to ruff the HK, cash the CK, venture across to the CA, hook the diamond. I'm going down at least two if it fails, so I assume it works. If covered, return to other top diamond, ruff a heart, ruff a diamond to leave (with 7 tricks in the bag and 1 trick lost)
QJ -- -- Qxx
KTx x -- x
Now a heart finishes RHO. If ducked, I ruff a heart, cash the DA, and ruff a diamond to attain the same position. Alternately, if RHO is 5323, I can cash three top clubs before embarking on ruffing the red suits high. My instinct sides with the former.
