Double, WTP? In recent experience, I have never encountered -470 or +100 in this situation. Meckstroth doesn't call this the "burn" vulnerability for nothing ...

The auction accidentally got deleted ..... (5♦) Pass (6♦) ???

[hv=d=w&v=n&s=skq9xxxhxdcakjxxx]133|100|Scoring: IMP[/hv]

And the other pair?

1. I psyched 2C on a similar hand recently (on BBO, and not in ACBL land), intending to expose the psych by passing the waiting 2D bid. Of course, the auction went as intended and LHO, sitting there with half the deck, thought I misbid and floated it. Four away when 6M makes by hooking against my partner. In retrospect, I don't think that this psych should have worked nearly that well as LHO could defend as if i opened a weak 2D if he doesn't suspect a psych. Psyching 1S on hands like xxxx x xx QJ10xxx can work very well by the same token, provided your partnership plays reverse drury. This one is actually legal in ACBL land, where real drury mixups are not all that infrequent. 2. Never. 3. I'd rather bid 3S with this hand. Also depends on the number of drinks :P

As West, Both Vulnerable, IMPs, you hold ♠AQ8 ♥84 ♦73 ♣AQT953. Bidding Proceeds 1♣ X XX 3♥ P 4♣ 5♣ P P 5♥ X AP

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 :P 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.

And the "expert" opponents chose not to bid with these hands? Clearly the auction clues are relevant and change the percentages.
