Sistem Penawaran Presisi ( Precision Bidding System ) atau sering disingkat Prec adalah sistem penawaran yang memiliki penggemar sangat banyak di Indonesia. Bahkan, dalam salah satu artikel Bert Toar Polii ditulis: Indonesia adalah Presisi !
Popularitas sistem ini terutama karena opening bid (pembukaan) 1C yang berarti punya pegangan kartu berjumlah 16HCP atau lebih. Cukup sampai disinikah sistem presisi berlaku ? Ternyata tidak. Karena itu, agar mendapatkan gambaran yang cukup lengkap tentang sistem yang berbasis distribusi ini, saya mengadopsi dari Sistem Presisi AMOX COMMUNITY yang rasanya cukup mewakili sistem presisi baku di bawah ini.
