Board 17 at Cobham in the evening:

An amazing hand, partner opens 1♠ and the auction continues and key card in ♥ is asked.  I answer 1 keycard (partner thinks it is 0) and auction signs off in 5♥ - I should have been awake and realised partner must have must have made an error, why are they asking if 1 is the wrong answer?  Am certain I should have gone to 6 on this auction - I didn't and a poor score ensues.

However, should we get to 7♥?

Assuming we play exlcusion Blackwood (I do with 2 other partners) - auction could go, 1♠, 2♣, 2♥, 5♦, 5♠ (showing 1 other than A♦).  Now - does partner go 7 missing the 2 key Qs?  I have shown 8+ HCP but 4 are A♣ and 4 could be in ♦ - I think 6♥ is all we can bid without more sophistication  

One of my bridge partners from back home has since commented that although you could be missing the Q♠, it's very unlikely to find one Op with 6 to the Q, if you find 4 to the Q, ruff them good for 7 - it IS worth a go at the Grand...!!!  Also, a better bidding sequence starts with a strong 2 in ACOL or 2♦ for Benji:

2♦  – 3♥  – 5♦  – 5♠  – 7♥  (You could try 5NT grand slam force to locate Q♥ , but makes no difference to locating Q♠ .)
