For no particular reason...

Suppose North and South are online pickup partners who play different systems but are under the impression that partner is playing the same system.

Assuming the bidding systems of your choice for North and South construct a N/S hand where 7NT has 60+% (or any reasonable figure) chances of making and N/S manage to reach it inspite of the differences in systems.

The more different the bidding systems, the better.

This is trivial

Assign one player a dead minimum opening hand for a given system.
Give the other player all the remaining points and a decent suit

Auction will start 1X - 7NT

Here's a Hypothetical

South is playing MOSCITO
North is plaing 2/1 GF

South will open 1 showing 4+ Hearts, North will (probably) just bid 7N

OK -- one from real life, sort of. I was laying a system called "bridge," but partner was playing something different.

Partner decides to open 1 with 5-5 in the black suits, but with a weak hand. You are responder, with a solid 7-card heart suit, headed by AKQJ10, with a side AKQx in clubs. To your surprise, RHO overcalls, white-on-red, 1.

Of course you smell a rat. But, how to unravel this? So, you leap to 4NT, which cannot be misunderstood, you think.

LHO competes to 5, clarifying the psychic.

Partner now had a "problem," at least from his viewpoint. For some reason, he decides that D.O.P.1. does not apply here. Rather, he decides to "pattern out" and bids 5. This, of course, convinces you that your side has all of the aces. 12 tricks are there by power, if partner has a mere 8 HCP's. Somehow that 13th must be there -- 7NT.

The hand is "60%" psychologically. Partner actually held only one Ace, with solid spades, the club Jack, and out. A diamond lead sets 7NT 8 tricks, but it seems about 60% likely that LHO does not find a diamond lead in this auction, from Kx.

South is playing precision with asking bids; North is playing 2/1 with crisscross minor raises.

1C-2D
3D-4C
4H-6C
6D-7C
7D-7N


Meaniing ; How interpreted ; Meaning ; How interpreted;
1C 16+ ; Opening 3+ clubs ; 2D-strong club raise; 5+ diamonds 8pts+;
3D ask ; cue bid ; 4C- Keycard ; 6 cards to 2 honors;
4H ask; 1 or 4; 6C-to play; void;
6D to play; accepting; 7C to play; WTF?????;
7N ; WTF??????

N: pass (13+, forcing)
S: 7NT (I have 13 tricks opposite a yarborough)

Okay, so it's trivial. But fun. And has the advantage of following Hrothgar's philosophy, but without the 1M opener.
