How to bid this Grand Slam?


This is the bidding of the expert. I like the idea to keep it slow and supporting partners diamonds after the game force. Lia's 3♠ should show a bit of support, but it is alerted as 20-23 points. The expert never checked that meaning. At that point, 4NT should be ace asking in diamonds, but it is alerted as 11-13 points and non-forcing which makes no sense now. I would not dare to say it seeing the confusing explanation. The expert again did not check it, and was surprised by 6NT. 7NT is then educated guesswork.

Clearly, there needs some work to be done in the explanations of bids and the bidding of slams of the robot. You really need to carefully watch the replies and must not assume that you know the meaning. If 20-23 points are the explanation you see, there is no option but to trust it and bid 7NT right away.

I finished in 6NT because I gave up finding an exact slam sequence with the robot. If North opens 1♦ with 23 honor points and two solid minors, it is hard to find a grand slam. Moreover, this slam depends on one side controlling the minors and the other side the majors, which is not easy to communicate, unless points are clearly limited.

This bidding got me stranded in 2♠ because of Acol. That's actually not bad. You cannot make it against good leads. But neither can you make 1NT, the contract you might reach by downgrading the hand to a weak 1NT. On almost all other tables, the bidding started with a strong 1NT and continued to a good heart contract for E/W by the bidding below. In that case, the "blocking" value of 1NT fails, and the direct mentioning of a spade suit works out to be superior.   But I spoiled that advantage by going down twice. Actually, I could have made the contract after the lead of ♣K. It is always tough to play 1 4-3 fit, and this is no exception. I started with a heart won by East who followed with a trump to prevent ruffs. I now can ruff only one heart at the table. The best line of play is to drive out the ♣Q now. If West takes it on the first round and returns a trump, you can play clubs to dummy and continue it. If he ducks one round, you need to find the finesse in diamonds t...

This is a nice one. You reach 4 ♥ , and West starts with the ♠8. If the trump finesse fails, you count 10 likely tricks, including one ruff of a spade at the table. But then there is also the chance to cash the ♣K for an overtrick. Easy. You are glad to combine all these options, and start a simple plan.  Cash the lead and make the finesse in hearts which fails. Another spade comes from West. When you notice that you are going to lose two trump tricks, you collect your tricks, ruffing one spade at the table at the end, and set all hopes to the club finesse which fails. One down. Everybody played like that, including me. You certainly spotted the way to make the contract? Of course. You could leave West with two trumps and throw him in after you trumped your space and cashed your  ♦ Q. Is this difficult to see at the table. Maybe. But you will definitely see West's 4 spades and hearts. When he discards the  ♦ J on  ♦ Q, the coup is very likely to work.

2NT are not makeable, but if you go down only once, you are good against 2♠ by opponents. 2 ♥  would be a nice contract and just make with good play, but opponents won't let you play that easily nowadays, not even the robot Lia. The lead was ♠5, East following with the ♠Q and won in the hand. Due to severe communication issues this hand cries for a try to let the opponents play into the finesses. So, I correctly played the  ♥ A followed by a small one won by West, who cashed  ♥ K too, the followed with the ♠10  because everything else helps the declarer even more. At that point, I went for the clubs, but the diamonds actually work, playing for one honor doubleton at East. Check it out.
