Related to the topic here, I was wondering if anyone had heard of systems where eg 1C 1D is *either* Hs or some other hand type.

It seems like it could take a lot of pressure off the other bids, but will obviously put you in a difficult spot if LHO now enters the auction (and maybe makes more hassle for the continuations than it's worth? - seems like it would inevitably lead to missing a few 2H contracts). Has anyone tried any form of this? What were your experiences?

Adam (awm) seems to be the forum expert on this style. I think he plays it himself and has certainly recommended it to others with plenty of details for the follow-ups. If he does not reply here directly then I would suggest messaging him.

When comparing different response structures the style of opening can be quite important too - over a Fantunes-style 1♣ opening you are going to have a GF hand alot more often than in Acol. Two other styles of responses you might compare are Moscito-style, with 1♦ as any GF hand (10+) and semi-positives; and 1♦ as any invite or better (7+) with other bids weak including a 1NT response as a weak hand with diamonds.

I cannot tell you how each of these compares for the specific system you are designing though. They all have pros and cons. One thing I am certain of is that transfers are the simplest 'good' solution which is why I suggested them first.

Thanks. Do you know of any online docs that describe the Moscito-style positive/semi-positive continuations?

Page 6 onwards of this pdf file from Dan's website has the basics.

You have me confused with someone else; likely rbforster. I play 1d natural in most partnerships; 1d double negative or GF relay in one strong club partnership.

I think I got "transfer or strong" confused with "double negative or strong" although we have definitely had some discussions here about the former. Presumably the latter would also be a suitable method over a Fantunes-style 1♣ opening too.

Thanks, that looks interesting. The main downside apart from susceptibility to competition over the first three responses looks like it would be missing 4-4 major fits when responder is balanced 0-9. I don't really have a strong sense of how big a loss that is. Presumably significantly worse at MPs than IMPs?
