If I were opener I would rebid 3♦ if my lho had not made the TO double. The double makes me suspect he has major values, so I still discount the ♠Q and just bid 2♦. The next round I would bid 3NT WTP? The TO double suggests 4 or less frequently 3 so they usually can run at most 4 hearts. 9 tricks in NT look as easy as 11 in diamonds. Would expect very few bidders to find the diamond slam. CTC scores 10 6♦, 10 5♦, 6 3NT, 1 partials. ATB 100% opener for final pass.
How could I disagree more. This hand is even much better for 3 NT when LHO doubled and pd bid 1
♠ freely. Your worry should be
♥ suit however LHO did not bid 1
♥, he doubled. RHO did not bid 2
♥. At worst, even if your pd has xx
♥ the odds are that they are split 4-4 is extremely high. Never EVER trash the whole value if a single honor. You would be amazed about the capabilities of singleton honors in your hand that opponents bid and I listed that in the past. For example just look at all 4 hands. That stiff Q disables them from cashing their 4 winners in spade suit.
But even if you trash totally the value of stiff Q, I would still bid 3
♦. After this post of yours, I decided to check the value of the hand in KnR with and without the spade Queen.
With the stiff Queen =17.55
Without the queen=17.35
