A Master of Go is a highly advanced Go AI program developed by Yuji Ichikawa. With its strong neural network based on Leela Zero, ELF OpenGo, PhoenixGo, Minigo, SAI, and optionally KataGo, this program serves as both a formidable opponent and a valuable teacher for Go enthusiasts.

One of the standout features of A Master of Go is its impressive performance on Apple devices. With the M2 processor on the iPad Pro, the program can perform playouts over 650 times per second using ELF OpenGo weight v1. Even on the A15 Bionic processor of the iPad mini, it achieves over 200 playouts per second, surpassing many notebook computers and rivaling desktop performance. Additionally, on the M2 processor of the iPad Pro, playouts are performed over 250 times per second with KataGo b18c384nbt. The program also includes other renowned weights for added variety.

It's important to note that the playout speed on older devices, such as the iPad Pro 9.7 inch with an A9X processor, will be around 10 times per second, and on the iPhone 6 with an A8 processor, it will be approximately 1 time per second. Despite this, A Master of Go remains stronger than most amateur players, although it may occasionally misread ladder patterns. Prospective buyers should consider this aspect carefully.
