'''Grob's Attack''', or the '''Grob Opening''', is an unconventional [[chess opening]] in which White begins with the move:
: 1. [[b:Chess Opening Theory/1. g4|g4]]

It is widely considered to be one of the worst possible first moves for White. [[International Master]] (IM) [[John L. Watson|John Watson]] writes, "As far as I can tell, 1 g4 is competitive with 1 h4 for the honour of being White's worst first move. Against an informed or skilled opponent, it is simply masochistic."<ref>John Watson, ''Mastering the Chess Openings, Volume 4'', Gambit Publications, 2010, p. 275. {{ISBN|978-1-906454-19-7}}.</ref>
