Do you open at the one-level with 4M6m hands?

Marston said he originally did so but found out that it often led to 4-3 fits in a major where a better minor suit contract is available, so he changed it.

Maybe you have that problem a bit less, at least over the 1♦ opening where you may use the weak relay on some hands with which Moscito would bid 2♠, but I think I would still raise with 3-card support on some hands, especially in contested auctions.

Some 4-6 hands can be awkward. The strongish hands are fine because 1♥ - 1NT/2♥ - 3♣ shows a good 4-6.
With a minimum and that shape, we have been known to suppress a poor 4-card major.

♠Jxxx ♥x ♦Ax ♣KQTxxx

"might" choose to open 2♣, then show as 3-1-3-6. This is rare.

Mostly we open 1♦ and accept the consequences. Either you play 4-card majors or you don't. It's worth noting that our style with three trumps is not so rigid. We tend to respond 1NT on most of the 4333s and some of the 4432s:

♠xxx ♥KTxx ♦Qx ♣KJxx

would bid 1NT over 1♦. I think (not sure) Paul would expect responder to bid 2♠ with that.

I enjoy your book!

Idea:

1♣ = Scamp 1♣ or Scamp 1♠

1♣-1♦; 1♠ = Scamp 1♠ possibly with a wider range (say "11-18" instead of "11-15")

1♣-1♦; 2♣+ = Asptro or better NT defence, possibly excluding major 2-suiters

1♣-1♥; 1♠-1N/2♦+ = Scamp 1♣-1N/2♦+

1♣-1♥; 1N+: takes care of all Scamp 1♠ hands (e.g. by simply letting 1♣-1♥; 1N = original 90s Moscito 1N)

1♣-2♦ = 8+, either S+H reverser or 5+S5+H (can afford to use 2♥ as a GF relay over this because of the guaranteed 9c+ H fit opposite the Scamp 1♠ type)

1♣-2♥ = 8+, S+H anti-reverser (can afford to use 2♠ as a GF relay over this because of the guaranteed 9c+ S fit opposite the Scamp 1♠ type)

1♣-2♠+ = Scamp 1♣-1♥; 1♠-2♠+ (9+c S fit guaranteed)

1♠ = Scamp 2♣, Scamp 2♦ or Scamp 2N

2♣+ = weak preempts

With your acrobatics, you free the entire 2-level for pre-empts, which is good. There is a price

1♣ = 16+ any, or 11-15 44M
1♠ = 5+♣ 0r 5+♦, no M, not bal

Not so keen on multi-meaning bids, partly because our aim is to attract a new group of punters. Also, bridge is a 4-handed game. Aggressive opponents would cause some problems.
