Acol Daylong - Feedback thread


diana_eva

Recommended Posts

As the Free Acol Daylong experiment has been spawning quite a few threads, here's an official feedback thread.

 

Please post comments about the free acol daylong and the robots used in it (Argine).

 

Same as with GIB reports, it helps to include the actual hand, or at least mention the board number and the daylong date.

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

It's an experiment for now, so it seems premature to dedicate an entire forum to Argine.

 

If Argine is unlikely to be used in future for other bidding systems (really? why?) then I can see a case, but even then I would have thought is it useful to BBO to distinguish discussions about the Acol Daylong format and geographic availability from discussion of the related robot problems and to keep each Argine/Acol problem in a specific topic to identify consistency and gravity, as we have always done with GiB and 2/1. But up to you, of course.

Might it not make more sense to open an "Argine Robot Discussion" forum parallel to this one?

That would allow people to continue to create a topic for each bug/discussion as has always been done, rather than rolling them all into one noisy cauldron.

 

I agree. GiB has enough to answer for itself without having to worry about Argine

Plus it might be clearer to new and less informed players that there are two different bots and styles of play

Argine appears to be just as hopeless at slam auctions as GIB is - in fact, I'd say worse.

 

My post the other day had it bypassing all cuebids and Blackwood to leap to slam with a missing control and no clue about the number of keycards (* edit - sorry aces; the lack of keycard is another giant disadvantage). I never linked to the hand, so here it is in full. I managed to make it, but we could easily have been off two diamonds, let alone numerous other possibilities..

Perhaps optimistic on my end, but 5?? With KQxx in their suit and four points outside? A 1.5% board dropped my average down to 70% :( (The field appears very weak at the moment.)

 

Note the really bizarre diamond play by the robots too. GIB sees letting the J hold as *comfortably* the best play at MPs (and IMPs too); can't see any excuse for overtaking.

 

Haven't seen the ACOL daylong, is it available for Canada?

Nope. Just GB,IE,AU,NZ.

This is the worst play bug I've seen yet:

After 5 tricks, North has just shown out on the second trump. The hand is an open book, as I'm guaranteed the SK and DA for the opening bid. West has a trivial 10 tricks (eg duck a spade, ruff the diamond high, and take the marked finesse).

 

Instead, West plays trump Ace and another, guaranteeing down 1.

Having never played Acol before I've been finding this daylong an interesting learning experience.

Many things puzzle me but the biggest one concerns the opening bid.

Playing 4 card majors and a 1NT range of 12-14, how do you decide when to open a balanced - or semi-balanced hand - 1X or 1NT?

As in 12-14 - 4333 or 4342 - 1S or 1NT?

If the fourth suit is now forcing to game in Acol then I guess I shouldn't be surprised that a 2NT response shows 4 card fit ;)

The explanations look strange, all the same: a game force with minimum 10 HCP and a 3NT rebid which promises exactly 4 card hearts when the hand is 5 card.

Outstanding slam bidding by Argine.

Very impressed with the way it carefully assesses keycards before determining the optimal contract.

I wasn't alone 48 players in 6D-1 or 6S-1.

Need an ACOL expert to confirm, but I don't think this can be right:

Double is "6+ HCP, takeout"

2N is "15-19 HCP, game forcing"

 

My other options were to show a 4 card major, or rebid 2, which showed 12-14..

 

This is the second negative double issue I've seen, with the other being that 1 (1) x showed 10+ points and said nothing about suits.

 

Also, I only just noticed a hand thepossum posted in the other thread. It was edited in later, so others might have missed it too. Well worth looking at, because it is truly insane :)

I've advertised the tournament to my club members who play on BBO and offered to deliver their feedback. These players are experienced club players who rarely play in district or national events.

 

"I found them a vast improvement on the usual ones. I could have done with the information they give when making a bid on the screen for much longer. I tried to bid using their system as I looked at my options of rebid which weren't always what was in my head to bid. Sometimes their system worked but not always. That may have been my error in how I played the hands."

I thought this one looked relatively comprehensible: the human should have had 6+ to intervene, Argine just followed the Acol principle of bidding to the length of fit ;)

I am not sure why 1c-1d is explained as natural or club support. We do play invented minors, don't we?

I continue to suspect we are playing invented Acol :)

 

I now have a less ancient and more specific Acol textbook ("Guide to better Acol bridge" by Ron Klinger, 1988) so I can check out just how many of these conventions were part of original Acol, if anyone is interested.

Of course systems continue to evolve until they become extinct or unrecognisable, but at least a name like "Modern Acol" might be appropriate.

What, if any, features are at the core of 'Acol'.

Is it possible to state say ~three elements that would cause someone to say "Ah, you play Acol"?

Not my system, but it was the first I was exposed to, albeit briefly and with little interest at the time.

But FWIW I would reply 4 card majors, weak NT, natural developments.
