Acol Two Bids

I have been asked by a number of people to explain Acol two bids. As far as I am aware the Sharples-Marx method has never been published.  When I first learned them they were called hands of power and quality. They can be one or two suited, never three suited. They are telling bids and are forcing for one round.  By telling bids I mean that opener after his initial bid will tell responder how many tricks they have. The starting point is at least 8 tricks.  Now some examples :

 

North
AKQJ654
AK
654
2

This would be about minimum for an acol two and opener would open 2 and rebid 3

A two suiter would look something like this:

North
AKJ765
AKQ2
65
5

This hand would open 2 and rebid 3

An extreme example might be:

North
AKQ8765
AKQ543

Here you would open 2 and rebid 7

 

Hands like:

North
AKQJ654
A2
32
32

are not Acol two bids--powerful yes but quality is lacking. 

The 2 opening bid is particularly useful because it means you have no great need to open 2 and rebid 3 which is always problematic. 

You hopefully get the idea so I will move on to responses.

Positive responses are firstly a single raise agrees the suit and shows at least one first round control.  A suit positive needs to be based on a decent suit since bad suits are useless unless it happens to be openers second suit. My suggestion is two f the top three honors.  

Semi positive responses are a raise to the four level shows decent support and two second round controls.  Marx argued that a raise to five showed decent support and three second round controls.  

Negative responses are simply bid the next suit up --2NT over 2. This is useful because it allows opener to distinguish between hands that have a four card second suit.   For example 2 2 "NT --woulld show four spades and 3 would show five spades.  Over a 2 opening 2NT is the negative so this is not possible.

Some examples will help:

How you procede from here is a matter of partnership agreement, my suggestion is that 3NT says were are almost certain to bid a slam.  Note opner can be pretty sure partner has ace of clubs.

Here after the negative opener shows four spades and responder can jump to 4 to show firsst round control--obviously denying club control.

Opener knows partner has a good spade suit so 7 is clear--7 too maybe ok.  

 

I aam not going t labor the point but I think this offers an insight.  Happy to answer any queries if you are interested.  All comments welcome and thanks to the kind people on here fi get the hand editor now.
