Dear Ed & Peter,
How would you bid these? Methods are 2/1 GF, 15-17 NT, Reverse Bergen Raises, Roman Key Card 1430.
(Steve gives us three hands. We moved the diagrams to our answers for convenience -Ed. Bridgevaria.com)
All of these occurred in a recent local duplicate. If you like, I'll be happy to provide full hands and our results.
Thanks in advance for you reply.

I put your hands in diagrams and I will give my bidding under each of them.

Maybe 2NT in West in matchpoints. To my knowledge there is no way to check on the quality of the clubs after Stayman. So I bid the most logical contract.

Difficult to find out in the bidding what's best.
Popular in Netherlands is a two opening by East, showing a weak hand with both majors. After that 3NT would be reached in two bids :-)

West bids diamonds one time at cheapest level after South opens, no further opposing bidding.
Before we discuss South's next bid:
- I don't think South should open a strong 2♣, since usually this will only make it harder to show the distribution.
- In view of North's space consuming 4♥ bid: my recommendation is that a 2NT bid by North over South's 2♥ reverse bid should show a weak hand; a Good/Bad or Lebensohl spin-off (and of course 2♠ would be weak as well). After 2NT South bids 3♣ (unless he is very strong). North then passes holding clubs or bids 3♥ with that suit and, as mentioned, a weak hand.
Thanks to this method North can show a good hand by bidding 3♥ directly over 2♥, thus saving bidding space.
Ok, having said this, South has a problem in the situation shown above. If you play 5♦ in this situation as Exclusion Blackwood ('Show your aces but ignore the ♦A') that's your bid. North shows two key cards with 5NT and there's just room for a grand slam try with 6♣.
So far the theory... I think I would just bid 6♥. Without detailed agreements it's almost impossible to find out whether seven is on.

Reply from Peter van der Linden ('North'):
On most points I agree with Ed. A few remarks though:
Deal 1: Agree with Ed's bidding. At first sight the 3NT does not look like much of a contract but after any lead by South it will look quite a bit better.
Deal 2: I am not happy opening 2♣ on a hand so poor in defence. Suppose North, the left hand opponent, jumps to 4♠ and partner doubles? He does not need much to do so: such a double is mostly used to warn West against further bidding. Fearing 4♠ might be made (with an overtrick?) West might just do that...
But also without interfering opponents 2♣ has its disadvantages: West has nine tricks, not a lot for a game forcing opening. And even if the partnership can in principle stop below game: there is no way of doing so if East has something like the ♠KQxxx and the odd jack, .
On the other hand: what alternative does West have? A 1♣ opening would give NS a free ride in the majors.
Thinking along these lines, more and more I am beginning to think of opening 3NT. After all, that is the most obvious game.
Deal 3: Firstly, I doubt whether 5♦ would be Exclusion Blackwood, Ed. 5♦ should be bid with a jump.
Then: after opening 1♣ South would be in serious trouble - he might lose the heart suit - after high level intervention in spades by West. The solution is a bit (too?) extreme perhaps but how about opening 1♥? In this case the fit would have been found immediately. West now overcalls 2♦ and whether the grand can be bid, depends on partnership agreements:
- If NS play 'fit bids', it will be difficult. North will bid 3♠ over 2♦, showing a good spade suit and a heart fit. In order to be able to bid 7♥ responsibly South would still have to find out about North's sixth spade or singleton club, whereas North would still have to find out about South's ♠Q and diamond void.
- If NS do not play 'fit bids' North would bid 4♣, Splinter. Now South could settle for the grand, after finding out about the ♠A and the ♥K, which should be possible.
By the way, I am not quite sure whether 7♥ is a good enough contract to bid it. A 4-1 split in clubs might be embarrassing (and that split is a little more likely than normal in view of west's overcall) while setting up the spades might be difficult since South then has to ruff two diamonds and maybe a spade as well.
