wrong opening

[dbl118]

This just happened. Human was North. Aside from east's terrible opening bid, west failed in the most obvious of signals and they couldn't find the easy switch.

I find it hard to believe GIB would open that badly. Was this a hand you played yourself or do you know the handle of the human? Then it should be possible to find the hand on myhands.

In first seat GIB opens that hand 1♥, in third seat it's 2♥. The suit quality isn't good enough for 3♥.

 

GIB's discarding is currently very simple: it generally discards from the longest suit it can afford. The only signal it gives is count, not attitude. Figuring out what partner needs to know is a hard AI problem (even human bridge players sometimes have trouble with this).

The hand was played under OP's handle, at precisely the time indicated by the timestamp of his post. 2♥ was the common bid for East-GIB. (I didn't check them all.) See traveller:

Aside from east's terrible opening bid...

I find it hard to believe GIB would open that badly.

In first seat GIB opens that hand 1♥, in third seat it's 2♥. The suit quality isn't good enough for 3♥.

Barry: Hopefully, your explanation was a direct response to Cloa's comment, and there will also be a response to OP's suggestion that the 2♥ bid stinks.

Why can't West open with that hand 1♦ its got 5 shortage TP and 9 HCP?

[barmar]

GIB's opening 1 bids require at least 11 HCP and 12 Total Points. West's hand has 14 TP, but only 9 HCP, so it's not an opening hand. And it's not a 3♦ hand because GIB plays disciplined preempts in 1st and 2nd seat; with most of the strength outside its suit, it's not a good hand to preempt with.

 

As for whether East's 2♥ bid stinks, I think that's a matter of opinion. I personally like wide-ranging preempts in 3rd seat; you're not likely to miss a game, and it makes things harder for the opponents. I would probably open 1♥ myself, but I think 2♥ is defendable.

 

This hand is kind of a freak (it looks like it belongs in a Ghoulash tourney), and freaks are hard for humans, too. I'm not sure we should make decisions about GIB's bidding and defense based on this.

GIB's opening 1 bids require at least 11 HCP and 12 Total Points.

It appears to me that East's hand meets this requirement.

In a poll posted in the SAYC-2/1 forum, neither 2♥ nor 3♥ has received a single vote out of the 18 cast.

[barmar]

OK, I'm convinced. Georgi, can you make it so?

[Bbradley62]

Thank you.

[georgi]

It's adjusted.

 

So hands like:

♠AKxx ♥Axxxxxx ♦xx ♣x

♠AKx ♥Axxxxx ♦xx ♣xx

♠AKxx ♥Axxxxxxx ♦x ♣x -> will open 1♥

etc which seem quite loaded with TP, not only HCP

 

 

♠AQx ♥Axxxxx ♦xx ♣xx -> will open 2♥

 

♠AQx ♥Axxxx ♦xxx ♣xx -> will pass.

 

The values in spades could be put in clubs, diamonds of course.
