Matchpoints, Acol 12-14 Notrump No special agreements. After partner replies 2♠ to your Stayman enquiry, what do you do. If you pass LHO bids 3♣. you bid 3♠ and RHO bids 4♣. Now what?

I'm not sure about the first pass, but it is not silly at MPs.

Having chosen to pass first time, I think you must pass the second time. Bidding 4S is not logically consistent and you can't double when you have no reason to think it is going off, let alone two-off.

I'd have bid 4s the first time. Yes, the hcp are not there, but voids are MAGIC! Whenever I'm on the fence about a bid, that's when I'll trot out losing trick count, and here you have 7 losers.

Because I disagreed with every bid south made (except for Stayman), I put other. I can't envision being in this situation to begin with. Instead of bidding 3s, I'd have bid 3d to give more info to partner. THEN if they compete, I'd double having given partner enough info to make a good decision.

I can't bid 3♦ second time the way we play although it does correctly show 4♥/5+♦ for us it's NF and denies 4 spades, I might well have bid 3♠. Third time I agree 3♦ is more informative.

Add another vote for 3D on the third round (instead of 3S). Hopefully partner can deduce from the pass followed by 3D that I have 4=4=4=1 or 4=4=5=0 (I suppose possibly (54)40 too), less than INV.

HardVector , eagles123 , etha , and Trinidad found the winning raise to 4♠.
I passed 2♠, competed with 3♠ and passed 4♣ which made for zero matchpoints.
For us, 3♦ would have shown 3451 or thereabouts.

After partner bids 2 ♠, I don't think responder should pass. I think the choice is between 3 ♠ and 4 ♠ depending on how you evaluate the hand.

But then again, after seeing the full hand, I'd never open 1 NT with an opening hand with a decent 5 card ♠ suit. If opener's hand ♠ 10xxxx and wanted to open 1 NT, that's a different story.

I have no real heartache passing 2s at MP (especially since we have already suffered through bottom 3) though I would have bid 3s. I think a vastly superior continuation over 3c is 3d even if it misleads p a tad about distribution. It is the short club that is the most interesting aspect of your hand and if opener can eek out a 4d bid you can correct to 4s. You have no guarantee 3s is right and 3d rates to be better then letting opps play 3c so why not make the descriptive bid?

Btw, once you elect NOT to go to 4s initially, I still think you should make the 3d bid, even if it shows 3451. You want to get partner to make a good decision on whether to compete or defend. If partner competes (bids 4d), you can correct to 4s.
