Having read the postings re: Acol with interest & as an Acol practitioner of 25+ yrs I should like to add my 'two-penny-worth' to the discussion. I dissagree with Draco that weak NT (12-14) is generally Tournament Acol but it is probably appropriate to playing casual bridge on BBO with non-regular partners - a feature of on-line bridge. I can well understand Orla being a "scaredy cat" (doesn't sound your style :)) of being left in 1NT with little support from ptr. In my experience this should seldom occur; either ptr will trans. for weak t/o or ops will intervene. It also seems to me that you have everything to gain by making a weak 1NT opening, esp. when non-vul. against vul. ops. I would go so far to say that the limit should be extended to 11-14 hcp when 3rd in hand. It may be possible to engineer a profitable sacrifice with little risk: often ops will not be able to collect a large enough penalty to compensate them for loss of their vul. game Concerning weak NT being a feature of Tournament Acol, in my opinion to use weak NT, irrespective of vul., in Tournament (playing for imp's) or rubber (playing for money) bridge, is foolhardy. Yes, bidding a weak NT when non-vul. makes certain hands (bal. 11-14hcp) easy to bid, but I am strongly of the opinion that when you are vul. you must treat it with respect. For this reason when playing with a regular ptr. I prefer the variable NT ref. to by Gordon who started this thread. Note of caution! .. this is fine playing with a regular 'understanding' ptr., but is difficult in BBO with casual ptrs as all responses have to be modified accordingly. Incidentally, does anyone remember when t/o doubles were ref. to as "Sputnik" doubles, or is my memory playing tricks :-/ Cheers, Charlie
