In hindsight, 3N looks really bad. I'm going to play Johnny Cochran and defend this villain however.
Lets say among 2/1 players that 3
♣ unndiscussed with such a hand might be ambiguous and possibly NF, as it would be in Lawrence partnership.
Lets also say 3
♦ confirms a weak 6-4 a la Mike. I think this is a reasonable treatment.
Where do you want to play the 4=0=1=8 hand opposite a weak 6-4 like:
1. Qx, AJTxxx, KQxx, x?
2. xx, KQJxxx, Axxx, x?
3. x, KQJxxx, Axxx, xx?
These are all hands all of us would open. Where is the optimal spot?
1. I like 3N. Its frigid on a spade lead and only the A
♦ offside makes it awkward.
2. No game is appealing, although at least 3N has a chance with lucky clubs. 5
♣ is hopeless.
3. Here's the type of nice minimum that gives 5
♣ a good play.
If we could with 100% confidence bid a forcing 3
♣, then 3N after the start of 1
♥ - 2
♣ - 2
♥ - 3
♣ - 3
♦... looks automatic. But if 3
♣ can't be bid, as it can't in my regular partnership (note: this hand didn't come up in my regular partnership), then 2
♠ looks indicated. Not that best description, but its forced on us if we want to stay below 3N. Otherwise, 4
♣ looks good and I thinks a reasonable alternative.
But why are we completely giving up on 3N because we have skewed distribution? Can't we reevaluate once pard shows us a minimum misfit? 3N is a stab, but its as good as a stab as 5
♣, albeit much less descriptive.
The actual West hand IMO is too good for the weakish 1
♥ /2
♥ /3
♦ sequence, but I'm concerned about Frances' comment that 3
♦ is patterning out than showing strength. I honestly don't know if Mike's or Frances' treatment is more commonplace. Topis to discuss.
As far as the other calls:
Once West shows a weak 6-4, whats the point of 4
♥? I think its bidding the hand twice.
5
♣ is an obvious attempt to rescue the contract. I suppose the 4=0=1=8 could pass, but 4
♥ isn't really playable. Yes I know that East has gotten the auction off course with 3N, so its hard to recover with a descriptive call now. 5
♣ can't be a cue bid - c'mon.
5
♥ is beyond words.
