Most gamers play variants of the identical bidding system as a result of studying a considerably new bidding system is a major quantity of effort. Most gamers aren’t excellent even with the one bidding system they know. Ask them to study a brand new one and they might be perpetually confused. Most gamers aren’t that critical.

I’m now going to disregard the mass of non-so-good gamers and give attention to the superior and professional gamers.

In most international locations, the primary bridge-tournament organizing affiliation regulates what bidding programs are allowed, exactly to restrict this technique. You’re not allowed any bidding system you need, and bidding programs and or conventions which can be more likely to be unfamiliar to opponents are banned, specific in video games the place every pair faces one another pair just for a small variety of boards. (In North America, it is fairly frequent for good-to-expert gamers to complain in regards to the laws put ahead by the ACBL on the grounds that it bans legitimately helpful conventions that aren’t that tough to arrange for.)

In tournaments with out such restrictions, that are primarily very excessive stage tournaments corresponding to world championships, gamers are required to reveal their bidding programs to their potential opponents a number of weeks forward of time in order that their opponents can put together.

Even so, there are some sensible the explanation why bridge gamers do not play extremely uncommon programs all that always. The first is that it’s really arduous to design a very good (human-playable) system that is very totally different from any of the generally performed programs. (Minor variations do not do a lot to confuse opponents.) If you make up a very new system, even in case you are good at it, the system is more likely to have some important weaknesses (which can merely be that it is very sophisticated and also you want to spend so much of psychological effort remembering what your bids imply).

A second is in how skilled bridge gamers make a residing. There isn’t any prize cash in bridge tournaments. Rather, bridge gamers are paid by rich sponsors who need to win (or no less than do properly) in tournaments by having good gamers play as their accomplice. It’s unlikely that their purchasers need to put within the effort to study an uncommon system or that their purchasers will have the ability to play the system properly. Even the skilled gamers who normally play with the identical accomplice (as a result of they’re employed to be a part of a staff the place the consumer performs with their skilled accomplice at one desk and two professionals play with one another on the different one) change companions typically when their typical accomplice is unavailable for a match (or doesn’t need to be vaccinated and therefore is taking a probably short-term pressured retirement).

(Most gamers in any respect ranges play with a number of totally different companions. I as soon as performed 4 totally different programs in per week; I can deal with that however most gamers could be fairly confused. And there are refined issues I are inclined to get flawed when switching programs.)

A 3rd is {that a} important quantity of bridge is performed with matchpoint pairs scoring, the place your rating comes from the way you do on every hand in contrast with numerous different gamers. If you’re a excellent participant, you play the playing cards higher than everybody else and might rating 60% (which is normally near sufficient to win) each hand simply by being in the identical contract as everybody else. Playing a distinct contract than everybody else introduces extra randomness, which you do not need. Certainly, there can be video games the place the arms fit your system, you get to higher contracts, and rating 65%. But 60% is first, and 65% can also be first, and there are additionally video games the place the arms do not fit your system, you get to worse contracts, and rating 57%. (Let’s suppose your system is definitely higher, so that you lose much less if you find yourself unfortunate than you win while you’re fortunate.) But now 57% is third.
