In the robot duplicate tournament #5497 (4/1/14), board #4, I bid 6 hearts but the GIB corrected it to 6 NT. The result is down 3. Do you think his bid is reasonable?

Thank you.

Here is your hand:



Within the confines of GIB's system it has a weird logic to it: You have shown (apparently) 33+ total points, counting your void as 3 and singleton as 2, and nothing for length. So according to the computer you were 11 points short of expectation. Never mind that you can (perhaps) virtually count 12 tricks. Never mind that with a 13 card suit you have only 19 total points but have 13 top tricks. Perhaps had you held 33 total points 6N would have been a doddle.

Once you get into the habit of hovering your mouse over your bid to compare the explanation with your hand held, you tend to appreciate that choosing a more convoluted route to get to where you know you want to be may be the surest way of getting the robot to leave you there, even though you give the opponents more room in the process.

Of course, bidding 6N is ludicrous in the human world, and maybe notice will be taken of examples like this, but for now this is how it is.

At least as bizarre as this hand is the one where your GIB CHO decided to introduce a 5 card Diamond suit at the 5 level and then insist on it at the 6 level opposite no support.Not surprisingly doubled for 8 down. Again, you had shown 25+ TP, rather more than held, but again, the requirement for 25+ TP for the bid is the oddity (not to mention West's failure to double 4S and North's failure to double 5H).

The defense and declarer play were pretty amazing too.

Next version will contain little help in this line. Probably for human bidders most likely.

So if you bid once,twice, etc and reach slam, with partner being supposedly silent all along, he will not move.

Of course if you have shown two suits or somehow last one is not your longest suit GIB would consider correction, but otherwise will calmly pass and rely on your decision to bid on your own.


Example:

1 - p - 2 - 3
4 - p - p - 6
p - ? ( GIB will stay ) directly 6 also implies, just more bidding will not change behavior of partner.

1 - p - 2 - 3
4 - p - 2 - 6
p - ? ( Now GIB would look at cards before passing and would correct to better spot.)
