New Android UCI engine: Viper 0.1.JA
Viper may be called a grand grand father of today's strongest engine Stockfish. It was created by Tord Romstad way before Glaurung which later gave birth to Stockfish.
Yes, Viper is old indeed. However don't expect it to become a whipping boy easily. It's more than though compared to many recent engines. Expect above 2600 from it on PC and no less than 2400 on Android.
I wanna see whether my assumption is accurate if i can find the opportunity to rate and place Viper in Rapidroid list.
