Your system is Acol with 4 card majors and a 12-14 1N. If you hold 4M4m32 you open 1m. Vulnerable at teams.

Do you upgrade this ? (If you do, your system bid is 1♠, but it's not unknown for you to open 1m and rebid 1N as this has advantages in some sequences).

I'll give the hand opposite later

[whereagles]

Depends on pard. If he can play cards by the right order, upgrade. Otherwise I'm hogging the hand LOL.

I open 1NT:
- no aces, 4333,
- the good intermediates could warrant an upgrade, but I would not because I have a lot to protect, I think it is important that this hand becomes declarer.

I agree with the bold bit, my decision was between 1♣-?-1N and 1N.

1NT

The intermediates compensate for the rest.
It is a maximum 14 but not worth an upgrade.
The hand is worth less should we end in a trump contract.

I would still open 1NT.

[Cyberyeti]

I opened 1N for the record

If you haven't answered what you open, try that before trying the second part.

Partner's hand is:

Do you want to be in 4♠ ? and how do you play it from the N hand on the lead of a smallish club ?

How do you bid after 1N-2♣-2♠, partner passed, in system, 3♠ is our only invite.

[Fluffy]

Passing 2♠ seems fine, look at the hand, partner has a maximum with litle wastage yet 4♠ is far from certain, then you think about partner with club honnors and...

We played 2♠, I ruffed the club, played a heart to the J and A, and LHO decided I wanted to ruff clubs, so played ♠Ax, 11 tricks. At the other table they upgraded so bid 4♠, then found the ♠J so we lost 10 IMPs. This was against the other good team in the Swiss teams in round 3 of 7 and turned a 12-8 win into a 15-5 loss. We thought it had cost us the event, but they lost 14-6 in the last round, we won 20-0 and burgled the event by 1VP

1NT looks obvious.

Io uso una valutazione della mano io cui punto di partenza e'stato (credo) lo stesso di quello utilizzato per la valutazione della mano indicata nell'appendice del libro "Il sistema Baba " (per realizzare un sistema ad uso dei computer) e che prende in esame sia la mano 4333 il cui punteggio massimo e' 37 punti per realizzare 13 prese con mano bilanciata che la mano 13000 il cui punteggio massimo e' 10 punti e che realizza 13 prese in quel colore mano sbilanciata. E' chiaro e sottinteso che devono essere apportati dei correttivi opportuni per ottenere una valutazione idonea che si esprime in termini di prese tenendo anche conto della/e dichiarazioni della difesa. Il punto e'che bisogna realizzare qualcosa che sia non complicato da maneggiare (La valutazione della mano di Lawrence credo e'molto dettagliata sui vari tipi di mani che prende in esame).Poiché si tratta di un algoritmo la regola di base che vale e' che più un algoritmo si basa su poche e semplici regole più esso è efficace.(Lovera)

Not a chance. IMO distribution is significantly more important than intermediates, esp intermediates in short suits. You have a bunch of very slow tricks, which pretty much means you're off in 3N if either opp has a five card suit. If either of them happens to have a four card suit, that might work too, after they've established the 4th trick and cashed their four aces (or two of them and a couple of honours offside).

Should they have misdealt, none of your 10s is even a single solid trick, so you might still struggle to reach 9 tricks before someone runs out of cards and calls the director.

1NT looks clear to me

[mikeh]

upgrading looks like resulting to me. Yes we have 10's and they aren't given any explicit weight in the 4321 count. But we have 4333 shape which, altho quite common within our 1N, is still a poor shape, and not as good as the more common 4432, and ignoring the 5332. Finally, and decisively imo, we have no aces. Hands without Aces should rarely be upgraded

This was more or less the thought process I went through in deciding to open 1N. Glad most people seem to agree

[gnasher]

I wouldn't upgrade. With the responding hand, I'd raise to 3♠.

On a club lead I'd ruff and play ♠Q.

If they take the spade and force dummy, I'll probably cross in diamonds, ruff the last club, and then try another diamond to hand. Even if that gets ruffed I'm OK as long as it was from the three-card spade holding.

If they duck the spade, I'll probably play RHO for ♠J.

Not sure you actually are OK on that line, 2nd diamond gets ruffed, heart to ace, third diamond ruffed cuts you off from dummy, now a club plants you in hand to lose a second heart.

[gnasher]

Yes, that's true, but only if ♥A is in the hand with the three diamonds.

I think the probability of a 3-1 diamond break is fairly low anyway. The opponents didn't bid despite having a 10-card fit and a combined 19-count, which suggest that the suits are breaking. And LHO didn't lead a diamond.

Diamonds were 3-1, LHO having the A♥/A♠ and 3 diamonds in a completely flat hand IIRC
