Argine doesn't know how to follow up in a checkback auction.



- showing 4-6, when it can't have 5-6 or it would have bid 1
- showing 7-9 HCP, when it holds 13

In a death-defying display of bidding gymnastics Argine attempts to make 6.



Interestingly if South decides not to double the 2 bid from East, the 4NT (Standard Blackwood Ace asking) is passed out.

Fixed. Why a pass changes it into non-Blackwood is bizarre. Equally bizarre is that 4 doesn't promise a single club, but is 'to play'.

Good point, the meaning changes if opps double an earlier bid.
Acol is a very strange system.

Reading this has inspired me to go back to 4cM on Funbridge and see what is going on.
It was never this bad.

I think we may need to have a separate thread for amazing slam bidding.

Completely nonsensical play on trick 1 gifts me the contract.


Nonsensical? Looks like standard 4th best from longest and strongest. If it's good enough for opening leader, it must be good enough for 3rd hand.

Well TBF it does say 'non-forcing' - maybe you need to press the double button a little harder.

I am still questioning whether we are in fact bidding Acol. It has some similarities at times, I accept. I try to cross reference with the EBU Acol Standard

Oh no. Its the Possum again. All I try to do is bid whatever system I think I am playing. I am very basic and remarkably disciplined most of the time :)

:) It also says that it has both majors, so pass is probably a bug.

Will the update at least fix this Pass?

Or should we just ignore the explanations and assume Acol (where neither 3 nor 4 is forcing, according to 'Guide to better Acol Bridge' by Ron Klinger) ?

Well, it's not documented anywhere, including the ACOL system notes, but Argine now plays RCKB. Not specific kings though.

Another ingenious slam by Argine.

Mistaking its own (perfectly sensible) 4NT for Blackwood on next round is something already documented here, so much for bug fixing.
But what would Terence Reese make of 6 explained as 0/3 side Kings?

Well, the description is accurate :) Never heard of 1430 king responses though, especially when it's rather tricky to hold 4 out of the 3 total.

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.

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

I am really confused about whether Argine opens the major or the minor with 4432 shapes outside the NT range. I suppose I could just investigate. It seems that it opens the major at least sometimes, but the hover info doesn't indicate that a 1NT rebid denies a 4-card major.

I like the new responses to 1NT overcalls, by the way. Well done, BBO!
