блинд

In the chess sense, derived from German blind. Compare German Blindschach, from blind (“blind”) +‎ Schach (“chess”). The poker sense may be borrowed from English blind, or German Blind, ostensibly from the English, and mapped onto the блинд (blind) pronunciation. (Can this⁽⁺⁾ etymology be sourced?)
