Apparition of naval battle in the air [1]

Mirage,
a chess program by Vladimir Rybinkin and Yuri Shpeer written in 8086 Assembly to run under MS-DOS on PCs [2], famous for its at times discontinuous, possibly fractional depth increments in iterative deepening [3]. During the mid 90s, Mirage was some years commercial, and later became freeware [4]. In the late 90s some code units from Mirage were incorporated into Centaur [5] by Victor Vikhrev and Alexey Manjakhin, which further evolved to the Dragon analysis engine of Convekta's Chess Assistant database [6] [7]. Mirage was further incorporated inside a Russian dedicated chess computer Debut-M with K1810BM86 processor [8].

Tournament Play

Mirage was quite active in the 90s, and played the WCCC 1992, the WMCCC 1993 and the WMCCC 1995, further Don Beal's UPCCC 1993 [9] and UPCCC 1994, and four Aegon Tournaments from 1994 to 1997.
