       | There are both "norms" and "rules" at play, here. Reading this
       | article made me think about watching high-level ultimate frisbee
       | transition from everybody calling their own fouls to having
       | referees.
       | 
       | I mostly watched this happen on usenet, and I haven't paid any
       | attention to this in years, so I may be getting some of this
       | wrong. But my understanding is that for a long time everybody was
       | (mostly) happy with the honor system of players calling fouls.
       | Then one guy forced that to change by aggressively abusing the
       | honor system, with the explicit goal of making everyone else to
       | decide that adding referees to the game would be the best
       | solution to him being a jerk.
       | 
       | In the case of Bridge, it sounds like a really interesting case
       | of an extensive system of rules, with a complicated and somewhat
       | opaque system of norms overlaying that. So, sort of like real
       | life.

         | We frequently had to call for someone to ref (an option then)
         | when we played the ECU (p)Irates.
         | 
         | They frequently pushed the limits of rules honor system. They
         | seemed to be proud of it. I thought it was sad.

             | To be fair, many of the players on their team were willing
             | to take their own medicine. I think most of them were
             | alright, but as in any group, it just took a few folks to
             | fuck it up for the whole team.
             | 
             | Once a fight broke out when one of our guys played rough
             | back at them (hacking, aggressive follow throughs, etc.).
             | He was strong and also knew how to fight.
             | 
             | Once the captains got together and had a frank discussion
             | about how to move forward (it worked that game).
             | 
             | Once we got the ref, we just told the other team that we
             | would require a ref in all future meetings. Their captain
             | understood.

           | You're right that the rules are only modestly complicated:
           | although they do run to dozens of pages _most_ of the
           | complexities are in trying to unpick and rectify situations
           | where something has gone wrong (unauthorised information
           | being accidentally given, somebody leading out of turn,
           | whatever).
           | 
           | That said, if you include partnership bidding systems within
           | the local 'rules' for a particular hand, the complexity
           | explodes. And, particularly at a high level, most of the
           | difficulty in being a tournament director is in making
           | judgement rulings where the partnership's conventions and
           | players' mental states are relevant to whether an infraction
           | has even likely occurred, still less how it might be
           | 'correctly' resolved.

           | ---no one is in a position to call it.

       | 
       | The problem is real and the national organization (ACBL), run by
       | seventy and eighty year-olds, has not found the courage to
       | address it.
       | 
       | There is no way to _prevent_ the exchange of unauthorized
       | information (i.e. not conveyed by a bid or a card played) online,
       | but the full record of the play makes it easy to _detect_
       | cheating with a high degree of statistical confidence, indeed
       | overwhelming after hundreds of hands. This is entirely practical.
       | It 's not even "big data". A 16-core desktop should suffice to
       | process a day's worth of data from Bridge Base Online (BBO) in
       | under 15 minutes, and update statistics in a database. Nicolas
       | Hammond, cited in the article, has done the analysis. I'm
       | confident it works, because I can see step by step how I would
       | replicate his work, well enough to verify.
       | 
       | But nothing is ever easy... There is bad blood between Nicolas
       | Hammond and the ACBL. To the ACBL's credit, they moved quickly to
       | develop a computer based scoring program at the dawn of the PC
       | era. And 30+ years later, they are still using the same ACBLscore
       | program written in Pascal by a single smart self-taught (now
       | retired) programmer, without so far as I can ascertain the
       | benefit of revision control.
       | 
       | Nine years ago, the ACBL tried to replace ACBLscore. Mr.
       | Hammond's software company was hired to do the work. It didn't go
       | well. The ACBL has never given an honest accounting of the
       | failure to its membership. Mr. Hammond hides behind the NDA he
       | signed with the ACBL. From experience, I'm sure there was shared
       | responsibility on a project chock full of weird legacy issues.
       | But it's impossible to apportion the blame.
       | 
       | From a programming view point, Mr. Hammond's cheating detection
       | pipeline is simple and clean, and free of legacy issues, a whole
       | different world from ACBLscore+. But the ACBL does not understand
       | this, will not bury the hatchet, fears lawsuits, and has insiders
       | and sponsors who don't want cheating investigated too carefully.
       | 
       | So a great intellectual game is dying. The ACBL brings more nails
       | for the coffin. They deserve the bad publicity.

         | Well said. I agree with everything you said. Anomalies in play
         | should be super easy to detect both during bidding and the
         | play. It is just a matter of collecting the data and running
         | it. They are already trying to do this with poker sites. They
         | are trying to detect people running solvers to determine the
         | right frequency of bluffing. If people start getting too close
         | to exactly 37% across X hands, they are obviously using some
         | kind of solver and data tracker. That makes it easy to ban
         | these players and confiscate their winnings as ill-gotten
         | gains.

       | The whole point of playing with a partner is exchanging
       | information in legal ways (bids, the cards you play). When you're
       | playing online, no one can tell if you're exchanging it in
       | _other_ ways.
       | 
       | Bridge tournaments should just sit the players at really big
       | tables so they're socially distant. No online at all.

         | Well, you can exchange in non-legal ways even in person. A
         | simple wink pattern could convey lots of information about your
         | hand shape or desire for game/slam. Even with the players
         | unable to see each other visually using cross blinders, there
         | are timing tells or hand placement tells that you can use to
         | indicate some information as above when laying down your bid
         | cards. They already removed talking during bidding because it
         | could be used the same way. If it is possible, someone will try
         | to cheat. The more beneficial it is, the more people will try.
         | 
         | For in-person play, there could be a review of played hands by
         | looking for lines or bids that seem "weird" and then going back
         | and looking at the video for discrepancies. If caught, ban them
         | and their partner from competitive play for life. Obviously
         | this is cost prohibitive and could only happen for the highest
         | level championship type events.

             | Besides, my favorite idea from it is secret coded bidding,
             | but the game doesn't really support _actual_ secret codes
             | without falling apart past low-level play (they 'd quickly
             | become entirely opaque and extremely specific, making the
             | whole thing kinda pointless), so they're not allowed, and
             | leagues often outlaw most of the interesting things you
             | could do with bidding (heavy jump-bidding bid systems, for
             | instance) in order to keep the game from collapsing and/or
             | to keep the people who want it to run _just a certain way_
             | without any surprises or hiccups happy.
             | 
             | I eagerly await my discovery of a card game that keeps the
             | parts of bridge I want to like, without requiring a ton of
             | extra restrictions that suck the fun (for me) out of it in

         | 
         | Take chess for example. Online it is considered enough that
         | you've played too consistently beyond human capability in order
         | to be deemed a cheater. This isn't proof, though, it just that
         | it defies astronomical odds. In over the board play, it is
         | required that the mechanism be discovered -- you have to catch
         | them with an app on their phone for example. Or that they break
         | tournament rules by not showing you what's on their phone.
         | 
         | The point above being that cheating would likely (eventually)
         | elevate to the point of building the ruleset such that one's
         | particular method of "cheating" is allowed, or can't be
         | discovered.
         | 
         | I think with a lot of things we're already there now. F1 has
         | people clearly "cheating" every intention of the rules, but if
         | it's not in the rulebook it is legal until the rulebook is
         | changed. Players in a variety of sporting leagues are only drug
         | tested with urine samples that have been beatable for decades
         | -- they're effectively not actually testing these players --
         | cheating has effectively been negotiated into the rulebook.
