In this auction, what do 3NT and 4♣ mean?

In this auction, what do 3NT and 4♣ mean?

Argine forgets it's playing ACOL and plays SEF here instead. Don't how SEF works, but presumably agreeing one of the majors as trumps somehow.

[smerriman]

Argine is horrible.

I was happy when 4N was described as Blackwood in spades, because I had a strong hand but no way to raise spades without repeated cuebidding.

 

Until Argine decided to play in no trumps, losing the first 6 diamond tricks off the top.

Well that's handy - two systems in one robot.

Randomly oscillating between them from bid to bid.

I remember several SEF contaminations playing 2/1, so no surprise that the same happens playing Acol.

[smerriman]

Can the leap-to-5M bid be outright deleted from Argine's database? It bids it so regularly, and (amongst other reasons) makes it impossible to have any form of meaningful slam auction, especially when it seems to have no idea what it's meant to mean.

Please..

On the most recent occasion, according to the definition and hand itself, it decided to use it on a keycard-less minimum.

I had one of those recently. Had no idea what to do but gambled on 6 and made it :lol: Total luck, especially with 2 losers in one of the minor suits

There is always someone who manages a 100% with 6NT though :)

[finesse157]

I have written a few pieces in the "something new" thread and in robot reports.

 

Generally, the Acolist robots bid very well.

 

A few things that would be nice to clarify in the system notes:

- what are the rules for which of two (or three) four-card suits to open?

- to what extend to we play Walsh style (Acolists tend to rebid Walsh style, of course if they open a major with 4M4m32 it is moot).

- FSF is game forcing (I suppose that is what is meant by "making the auction forcing".

- The 1NT rebid is 15-17 (should be obvious, maybe, but isn't to British club players :) )

- Count signals are high=even

 

I would whole heartedly disagree with the "bid very well" comment. Playing in the free daily, Argine has a WTF ratio of about 1 in 8 hands. Anything involving a Q bid is going to be a disaster. The definitions are way off for too many sequences. However worst of all is the hand valuation. In response to a 1S opener, both of these were "worth" 3S...

Watch Argine convert 3NT+3 into 3NT-2.

Unfortunately, because I foolishly opened 1♥ I only managed 5SX-3.

I'm staggered than 5NT wasn't Blackwood, Ace-asking. Well, not according to West, anyway. Might have been 1430 king asking, excluding diamonds, for East?

 

But yes, I enjoyed the Q♥ play.

[smerriman]

Please..

Pretty please.. it bids it almost once per tournament, with a different unknown meaning every time. This one similar to thepossum's above, but it doesn't show a single thing it hadn't previously other than a spade fit.

Argine has a game force opposite a 2NT overcall. It decides to bid 3♥, natural, showing 5 hearts, and 0-11 points. Not even sure where to start here.

[pilowsky]

On the plus side it seems to emulating actual human Bridge as played at average club level - so that's something.

 

I just played the same hand - good grief.

Nice use of Blackwood. I didn't bother replying.

[smerriman]

I would whole heartedly disagree with the "bid very well" comment. Playing in the free daily, Argine has a WTF ratio of about 1 in 8 hands.

I would whole-heartedly disagree with the "about 1 in 8 hands" comment. It's far more than that. Today..

 

On board 1 we have Argine doing its usual thing of escaping from a doubled contract to use Blackwood with a measly 1 HCP to get to a worse doubled contract.

 

On board 2 Argine brings up the broken 1♦ showing 1+ ♦ response, leaving it stuck for all future bids; it decides to show an 8 count as a 10 count and gets us to a no-hope game.

 

On board 3, Argine brings out the undefined leap to 5M, expected every tournament. (Yes, I know the Acol opening bid is 1♠, but that's no excuse).

 

And on board 7, Argine decides an 8 count in diamonds is a slam invite opposite a balanced 15-17.

 

It's time to start working on GIB again, now that the 'I wish BBO would switch to the much better Argine' strategy has been tested. Kudos to the original GIB developers for being much better than anyone realised, but it can be improved.

[smerriman]

LOL! Argine just asked for keycards, found it was missing one, and thus bid the grand slam. That's a new one.

After I bid 4NT - which apparently means "quantitative invitation to slam - Non forcing".

Argine responds by telling me "6♦ blah blah blah - fit".

But a fit in what?

[/hv]

[smerriman]

Not sure what you're misunderstanding. Seems to match the definition precisely:

 

Fit: 1. sudden attack of convulsions and/or loss of consciousness

What lead does the double suggest?

And btw, how does North investigate a slam in spades using ArgAcol?[/hv]

The defence should be an open book due to the 3nt opening so it's hard to see how East can blow it up. Maybe all the sims gave North a club void so that any non-club lead at trick 2 leads to one down, and then it chooses randomly?

I've used G3NT a few times with Argine and only once did it respond 4♣p/c

I'm still not certain what criteria it uses to decide.

 

With a human partner would you still pass with the South hand?

Good question. I usually pass 3NT without much thoughts since 3NT isn't doubled and 4♦ may not be any safer.

 

But on this hand I probably should have bid 4♣ as 4♦ just requires partner to have no more than two hearts, or maybe opps don't take their heart tricks on time. Also, 3NT-1 (or -2 depending on how the heart split) is a likely bad score as it doesn't look like opps can make anything.

 

Another option is to bid 5♦ to rightside the contract. On a spade lead it is easy for them to find the heart switch if my hand is in dummy. Unfortunately, 4♦ isn't to play so if I want to declare myself I have to bid 5♦. On a good day, partner has a stiff heart so 5♦ is cold regardless of who declares.

 

Then again, if I pass I can bid 4♦ if they double it.

 

I don't think it should matter what fabric opps are made off. Except that now I know about this specific Argine weakness. Unless it was a simulation fluke.

The Daylong that just closed

I made 6H on this and wondered if there was a squeeze or advanced play available, am either not good enough or couldn't see it so claimed all but one of the remaining 5 tricks

I did wonder how a couple of tables made 7, checked DD. Here is one of the (anonymised) beneficiaries - or expert exponents should I say

 

Apparently there was a unique squeeze available. You need to wait to the penultimate discard. I am still looking hard just in case I can see a menace that I missed - always play to the last trick at MPs
