After West passes and North opens 1, East psyches a 1 overcall. Would your partnership be able to reach the cold grand slam after that? We lost 13 IMPs after only bidding to 6.

Please feel free to comment. Note: Despite holding 12 cards, opps were silent for the rest of the auction.

The psyche doesn't make it easier.

How about:
1-(1)-1
3-5 (Exclusion)
5NT-7 (2 without Q)

In my opinion bidding should be as follows:

1 - (1) - Dbl //Dbl - gives some points and probably something in
1 - 4 //1 - 4 cards in ; 4 - Splinter
4 - 4NT //4 - cue-bid (obviously A/void); 4NT - Blackwood
5 - 7 //5 - 2A without Q

Additional Notes
----------------
In this bidding scheme there is no information about the second Ace of North. So, if 4 is void, then North Aces must be in and . If 4 is A, then we don't know which is the second. If 4 is followed by Dbl from West, then A must be there, and North has the other two. The worst case would be North to lack A, and East to lead it. In any other case 7 is possible and therefore must be bid.

Another way is to use lower level Splinter to insure levels for cue-bids, which however sometimes may end disastrously with 4 contract to play. Nevertheless, there is a wise rule in bridge bidding which says: "The lower you bid in game/slam forcing, the stronger hand you promise."

Hallo Vuchev and welcome to the BBO forums. The majority of players here play the double after 1 - (1) to mean one of:

a. negative, showing precisely 4 spades (by far the most common);
b. stolen bid, showing 4+ diamonds; or
c. transfer, showing 4+ spades.

It is rare for a modern player to use the double to show points + values in hearts.

You could also simplify your auction along the lines set down by Rik (Trinidad) before you. Many play a jump to 5 over 1 to ask for key cards ignoring the diamond suit. This convention, known as Exclusion Roman Key Card Blackwood (XRKCB) or Voidwood, allows South to find out about the A and A without the message getting lost from the A.

In any case, this is quite an advanced auction so do not worry too much about things like XRKCB for the time being. Do read some of the old threads though - I promise you you will learn a lot here if you are open to it!

difficult

with a 2 loser hand and pard opening I will start with 1s.

who knows perhaps I will be able to bid exclusion in d at some point but at this point difficult.

if the opp bid I expect it to get more difficult, if they pass then easier

I know this is in the natural bidding section. It is an interesting problem, natural or otherwise, I think.

Playing a strong club, the auction might likely be (p) 2 1- ??
Would that inhibit a heart psych? Get a 2 overcall?

The resulting bidding could still get interesting. Perhaps 2 hearts doubled is for penalty. Perhaps a trap pass comes into play since responder knows that opener might have a 4 card major (spades, nearly certainly) and will get the chance to bid it, or rebid clubs cheaply. My partner and I have lebensohl available against the 2 heart overcall (or even 2 diamonds - but we would normally double 2 diamonds since it stole an artificial query about whether opener had a 4 card major).

1 11-15 hcp, 5+ clubs in a good suit, possibly including a 4 card major.
