Just started playing a basic transfer response structure after we open a major. If RHO doubles, or overcalls 1, is it reasonable to play an iterative one-under ladder of responses e.g. after 1 X then:
1 = 1N
1N = clubs
2 = diamonds
2 = solid heart raise 7-9
2 = weak heart raise

We're just starting with it so something easy to remember is good, but wasn't sure about the 1N bid - is there value in having a natural 1N there for responder? What's a typical structure here? Thanks.

You might find it useful to look at https://users.cs.fiu...odifiedC1MX.pdf for an existing set of agreements for this situation. They differ from you on 1S (they play that as transfer to clubs) and 1N (they play that as semi-forcing).
You must know the rules well - so that you may break them wisely!

If your partnership play 4-card majors, a simple response structure is feasible:
• 1M (X) ??
• Pass = BAL (3 card support - if you bid again).
• 1N = NAT N/F.
• XX ... = TRF to next suit e.g.
• 2M-1 = TRF 7-10 HCP 4 card support or 12+ HCP 3 card support..
• 2M/3M/4M = PRE NAT.
• 2N+ = ART 11+ HCP 4+ card support .
• J/S to 2+ = SPL singleton or void 4+ raise to 3 or 5.
• J/S to 3+ = SPL void 4+ card raise to 4.

We keep the XX for penalty (I think you need that) and 2 is natural. We don’t have a bid to show a balanced hand 7-9 with a stopper in, presumably, the other major. Not convinced it is necessary to have that.

I think your agreement is the most common "standard expert" one here in the USA. You laid out the H sequence. The S sequence is similar, with XX being the "transfer" to 1NT (it could be a three-card spade limit raise, too).

You do NOT need XX for penalty. You just pass the double and then double when the bidding comes back around to you.

Cheers,
Mike

Adding to this after playing it a while - it seems to be working ok for us. Certainly the core idea of discriminating major suit raises is massive, but we've had a few times where pard is stuck for a bid holding a natural 2N sort of hand.

e.g. 1 - 2 (overcall) to pard holding something like a balanced 10 no fit.

We don't currently have 3 defined - is it reasonable to use this bid as a catch-all invitation? Like 10+ no fit.

We play 1 - (2)

2 = simple raise (in reality this is fairly wide range)
2NT = transfer to clubs
3 = transfer to diamonds
3 = good 3+ spade raise (essentially a limit raise)
3 = mixed raise, 4+ spades, 7-9 points
3 = pre-emptive

There are trade-offs given the limited space, but we are happy to miss out on differentiating between a good and poor raise to two spades.

We also changed from distinguishing between three- and four-card limit raises to gain a mixed raise.

I’ve always played that redouble is natural (value showing) as is 1, and transfers start with 1nt. Basically we sacrifice the natural 1nt to get better definition on hands with a long suit and on raises.

In higher auctions like 1-2 I’ve found that distinguishing between the invitational and game force raise is quite important. Opposite the invite opener will often want to jump to 4 which is great for concealment but awkward when responder has a mild slam try; also the GF raise creates a forcing pass if opponents bid more while the invite shouldn’t. This seems a lot better to me than distinguishing 3- and 4-card raises or mixed vs weak raises (mixed raise can always bid 2 and compete to 3).
