LOL Jay. Agree and it would never arise in our system. All 11-17 5M332 opened either 1♣ or 1NT. 1M 2m; 2NT shows 18-19.

When I simmed the hand, I was surprised that 3NT makes close to half the time, and pulling up in 2NT makes about 80%. Give opener a dozen points or so on average, and responder a max of about 4 for passing, and the balancing 1NT holding tilts towards the max. Whether ruminating this was cause for the hesitation I have no clue, but the 2 bidder should have been inviting.

IMO the glacial pace of expert tournament play makes it unwatchable for all but the most serious and already-committed fans. Casual onlookers would vow never to take up the game zzzzzzz. Something along the lines of fast pairs speed might have a chance.

Transfers beginning with Double in those positions. (1) 1 (3), then

X = diamonds
3 = hearts
3 = at least constructive raise
3 = competing

You can ‘split raise’ using the transfers. You might try 3 with Qxxx AKxx xx xxx or whatever.

As Kit writes above, the distinction between raise strengths arises most frequently.

No clue, but I do note that Abstentions are close to overtaking Italy.

Some play them through 3m, if no jump is involved. 1 (2) 3 is the ‘last’ NFB.

I think it might be interesting to try ‘self-alerting’ (to the table, not just your screen-mate). It would clear up this kind of mixup, and countless others, because the 2 bidder would have announced ‘5-5 in the majors’. Sure, partner would be alerted to the meaning of your call, but you’re supposed to know your system anyway.

It comes with a whole set of different issues but they might be more manageable than the current set. For example, the 2 opener you announce, had better be the one on your card lol.

My partner thinks this ‘idea’ is insane.

He doubled? Oh yeah I see what you mean. You’re seldom wrong Richard, thanks for spotting it.

OK tweaked the sim to give opener 5+ diamonds and at least KJ or so … shouldn’t make much difference but we’ll see. Yes it slightly lowers the chances. 6 still close to 40%, 5 down a smidge to about 85%, and 3NT down to 65%.

For what it is worth, and that might not be much, a simulation has 6 making about 40%, and 5 close to 90%. 3NT makes some three-quarters of the time.

I gave opener 11+ HCP, 4+ diamonds, no 5-card major.

I looked at 400K leads against notrump contracts, and KJxx was a cellar-dweller.

Paul: Craig will no doubt reply, but I was curious. Results for Eric's hand are pretty much equidistant between results for 4333 14- and 15-pointers, all played opposite balanced 10 HCP. For 14-HCP 4333, chances of making 3NT are 38.2%. For Eric's QJ3 QJ5 Q986 AQJ chances are 48.1%, for 15-HCP chances are 59.5%.

Sample sizes were 3K. No constraints for the opponents' hands. Error margins smallish — second batch for Eric's hand make game 49.2%.

I agree the ‘no major fit’ condition throws off the numbers some. The 3343 test hand misses a bunch of 5-3 fits when matched up with 5M332 opposite, and those 5-suits generally play nicely in notrump.

When I include those fits, I find the test hand sits closer to the 15-pointer than the 14-pointer.

I did a 1K sim which should be ‘good enough’. Partner has the queen alone about 24% of the time, the ace alone about 13%, and both about 1%.

Double dummy solvers think that hand is closer to average than one might think, if played in notrump. Opposite 9 HCP in a balanced hand, it makes 3NT 35.0 % of the time. A random balanced 15-pointer makes 3NT 37.5% of the time. Both sims 5K in size.

You could play transfers there. X is clubs, 2NT is natural, 3 is diamonds, 3 is quality raise, 3 just competes. You can use the transfers to stall the auction, to maybe show a nice asset, then later raise hearts.

Shouldn’t make a lot of difference to the ranking of hands. OK if responder is balanced 7 HCP

Hand #4, the ‘worst’ hand, KQx QJx KQJ KJxx, scores 42%

Hand #3, the hand nobody selected to be worst, KJx QJ KQxx AQxx, scores 37%

The tweaked hand, removing doubleton QJ, KJx QJx KQx AQxx scores 55%

That bad hand I composed with ‘xx’, KQJx xx KQJx KQJx, scores just 32%

The problem with downgrading (or upgrading for that matter) is you don’t know what strain you will end up playing. Hands that are best for suit play have aces and kings and possibly ruffing opportunities. Hands best suited to notrump play have honors scattered about, no weak suits especially xx.

Hand #4, the worst hand by popular choice, makes 3NT opposite a balanced 8-9 HCP hand 81% of the time. Hand #3, nobody’s choice for worst hand, makes 3NT just 62% of the time.

That ‘weak’ 4th hand has no weak suits. If I rebuild #3 to remove that ‘weak doubleton’ QJ, so the hand becomes KJx QJx KQx AQxx, now we’re cooking with gas — that hand makes 3NT 84% of the time. 4333 hands are routinely disrespected, but with scattered honors, they compete with even 5332 hands.

I’ll try for a really bad hand …. let me try KQJ xx KQJx KQJx. Yup, that ‘xx’ drops the chances of making 3NT to just 41%, scarcely half the success rate of the consensus ‘weak’ hand.

The sims were quick and dirty 2K samples.

Sometimes the 1 response to a 1 opener isn't genuine.
