Interesting hand from Zenith yesterday

[thorvald]

Playing with the advanced bots in the Zenith daylongs, I got this hand:

 

[hv=pc=n&s=sq8653hq7d9c98643&d=w&v=b&b=4&a=1d1s2d?]133|200[/hv]

 

At all 15 tables this was the start, and you have to decide how to continue.

 

Normally with 5-card support it is ok just to jump to game, but with all red I wasn't sure it was the best, so after some considerations I settled with 3♠, and got the following continuation:

 

[hv=d=w&v=b&b=4&a=1d1s2d3s4cp4np6dpp?]133|100[/hv]

 

4♣ was natural (19-22 points), and 6♦ was odd number off keycards and a void (probably in ♠).

 

Is this the time for a sacrifice?

 

I decided not, and the bot quickly picked up all 13 tricks on this layout:

Well not a great result and I got 25% like 7 others, but interesting how to get a decent score.

 

One player did sacrifice in 6♠ and got 57%.

 

One player did not support partner at all, and the bots found a 4-3 fit in ♥, making 12 but worth 64%.

 

Three players jumped to 4♠ and two of them played a trump to early, resulting in 3 down, but still 75% - the one playing better went only 2 down and 86%.

 

Now the last two players found the right solution

I am not sure, why West couldn't bid 3♣, but the two players got 96% for their shared top.

 

Interesting how the middle road gave the bad result.

You have to love the description for 4♣ -

 

4 ♦ ... twice rebiddable ♣
