My “controversial” opinions:
Before money is spent on large tournament prizes or professional salaries, Go associations should ensure that wood boards and glass stones are the minimum quality of equipment at tournaments. Further, once that is achieved there should be a long-term plan in place to gradually replace those with yunzi or slate and shell, if even over a period of decades.
Also, being a higher rank, like a dan player, shouldn’t necessitate receiving a higher quality of equipment; if you want to “level up” your equipment at a tournament, you should have to pay an additional fee, and this privilege should be available on a first-come-first-served basis.
If you’re paying year-membership fees and tournament fees to the British Go Association, for instance, you shouldn’t have to play with plastic stones because you’re a “lowly kyu”.
