More on weird relay systems:
One thing that I did with my relay system to take full advantage of the limited openings other than 1C, and put maximum pressure on opps, was use what were, in effect, negative responses. After a 1M opening, a 2m response (and also 1S - 2H, though I'm not sure it was right to do that) showed invitational strength (around 7-11 HCP), a good 6+ card suit, zero interest in opener's suit, poor support for any other major suit opener might rebid, and no better than average support for the minors.
(To understand the rest, you also need to know that we were using canapé openings: with two-suiters, we opened the shorter suit, and rebid the longer; this rebid was never forcing. The basic advantage is that it was easier to stop in a sensible two-level contract with ill-fitting hands. A lesser advantage is that frequently opening four-card majors makes competition easier for us and harder for the opps; obviously, to do this one has to be comfortable playing 4-3 fits [because you often have to raise with three-card support]. Recall that our strong hands open 1C, so the canapé aspect doesn't adversely affect game-going auctions too badly, nor slam auctions much at all.
Also, we played that a 1NT response to 1M was forcing and unlimited, and could be made on anything form a slam force to a zero count. After a 1NT response, opener's first rebid was basically natural, which is why this wasn't a prohibited "relay system". Most strong responding hands went through 1NT, though we had available preemptive, limit, and forcing raises, plus the equivalent of strong jump shifts and a weird bid to show a game-forcing two-suiter.)
An example will illustrate. Suppose responder holds
Kx x xxx KQxxxxx. Partner opens 1H. For us, this promises 4+ hearts and 8-15 HCP (16 if 5-3-3-2), and does not deny a longer second suit. A misfit looms: if opener has a one suiter or a heart-spade two-suiter, getting too high is a live possibility and game a near impossibility. If he has a heart-diamond two-suiter then 2D is the best contract, and if he is 6=4=x=x we want to play 2S, but these are narrow targets; most of the time partner is weak I want to play 2C, while if partner is strong I want him to judge his hand knowing that I'm one-suited in clubs. Also note that if partner is weak the opponents may have game, in any of three suits (hearts is quite possible) or NT, while if partner is strong but misfitting, the best possible result is an opponent overcall followed by a standing-on-the-chair double.
With this hand we respond 2C (alert: natural but not forcing). With a crappy hand, partner passes; we are almost certainly in a profitable contract, making or a cheap save. With middling to strong misfit, partner can still pass, and opponents had better judge carefully. With decent fit and strength, partner invites or bids game.
So, for opener:
- xxx Jxxxxx AKx x: pass; good luck to opps to find their spade game
- AQxxx Axxx KQx x: pass, and saw opps off in anything they bid (particularly as heart ruffs will usually be available)
- Axx QJxxxx x Axx: raise to 3C, invitational, so pard can show a diamond stopper
- Axx QJxxx Kxx Ax (NV, as this would be opened 1NT vul): bid 2NT, natural and invitational
- AQ Jxxxxx KQ Axx: bid 3NT, which will usually make
- AQJxxx Axxx xx A: bid 2S, as 3C will be safe if responder hates spades (thus nearly promising the seventh club), but in this case probably leading to the good spade game.
With those same hands playing standard, the auctions go:
- P - 3C, or 2H - P, arriving at either a bad contract, or a somewhat worse one than 2C, and making a spade contract for the bad guys easier to find after fourth seat doubles or bids spades (which is far from safe against us)
- 1S - 1NT; 2H - 2S; maybe a winner at matchpoints but have fun if trump doesn't split
- 1H - 1NT; 2H - P; probably making but definitely inferior
- 1H - 1NT; 2H - P (or 3D), again arriving at some inferior spot (but if 1NT isn't forcing, getting to play 1NT, which admittedly is best)
- either as in (3), or an inspired 1NT opening that ought to lead to 3NT
- 1S - 1NT; 2H or 2S (opinions differ on how to bid these hands) - 2S or pass, though it's possible game could be reached.
In general, we get to at least as good a spot as the natural bidders more often than not, and it is nastily hard for opps to judge what's best, while opener will almost always know what to do over competition. It is this somewhat less of an advantage against really good opposition, which helps explain why (1) top pairs don't, as far as I know, play this way; and (2) why Bob Hamman had little problem working out what to do over one of these auctions, when we played him in a sectional. But against non-experts, it rocked.
It is not the relay aspect of the system that makes this method work, but the limited nature of the opening bid, so it would work even better in a more normal precision context in which opener promises 11-15 HCP, not our ridiculously weak requirement of a shapely 8 count.
In general, the more limited bids you have available, the better equipped you will be; this is just an example, though one of my favorite ones.
