mr1303, can you explain all of the bids in your auctions please. None of 3♣, 3♦, 3♥, 3♠ or 4♣ is clear. My guess would be that 3♣ and 3♦ are natural with the rest cues and no LTTC being played, but it would be nicer to know for sure and this will come up again so better to say something now.

Phantom

 

1♦ - 3♣

3♥ - 3N

4♣ - 4N

5♣ - 5♥

6♦

 

Translation:

S: Overcall, N: this one takes some explaining... North is pretending East opened 1♣ and partner overcalled 1♦ (as usual for the system) but then West raised to 2♣, so this bid shows a diamond fit and invitational or better values (which is prety strong considering S could have 8 points with a good diamond suit)

S: heart stopper and non-minimum values for the overcall, N: stoppers in clubs and spades

S: Gerber, N: 3 aces

S: Gerber, N: 1 king

S: to play

 

Akward auction. On a really bad day, South might even let things languish in 3N (though he shouldn't, given the strength that N showed with the phantom cuebid).

Molybdenum pass system:

 

P - 1♠ (Opening hand, GF response)

2♦ - 3NT (natural, 4-3-3-3 hand)

4NT - 6NT (invite, accept)

 

edit: the south hand passes to show an opening hand

Unnamed Homebrew Diamond:

 

1♦-1♠ 16+, excluding GF / 8+ almost any

2♥-2♠ single-suited ♠ OR short ♠ OR both minors / relay

3♦-4N both minors, longer ♦ / RKCB

5♠-6♦ 2 with Q / to play

 

The jump to Keycard is inelegant, but it works because N has such good controls and because S has promised at least 5-4 (and in that case will have quite concentrated values).

Unnamed Homebrew Diamond:

Did South limit their hand at some point? I cannot see why North has not made some kind of grand try here. How would the bidding be different if South had the ♣Q?

South is still unlimited - we tend to be quite cautious about looking for grands since (95% of the time) we are playing in a field where bidding the slam is enough to win IMPs. It's possible that N uses another method to look for slam - 4♦ should be a nebulous slam try, asking for first-round controls - but we would have difficulty locating the ♣Q on any sequence. It's the knowledge that we can't find out that makes us stop in 6.

South opens 1C. No interference. NV vs V. Please voice your opinion on interference in the "comparing systems" thread.

1C - 1D; (12--16 "any" unbal / 15--17 bal -- Relay, 0-7 or GF)

2D - 2H; (5+D, no 4 card major, unbal -- GF relay)

2S - 2N; (4 clubs -- Relay)

3C - 3D; (High shortness -- Relay)

3H - 4D; (1-3-5-4 -- Sets diamonds as trump suit, "natural" continuation)

4H - 4S; (cue bids)

5C - 5D; (cue bid -- suggestion to play, but slam interest with 4D)

6D - P;

 

North could ask for aces and kings, but the bidding would get pretty high. DCB would probably handle this one better too. Since south has a maximum (even though the sQ isn't that great) I think we would get to slam.
