So, 1. g4 is Hiarc's vote? Awesome.
What is the worst first move for White? The UNBIASED thread, all trolls welcome

If this is still open, I vote 1. axa8=Q, which allows black to mate in 2534, the fewest of every first move that loses.

what is a "troll"?
(JBHMD)
Ah, good question! "Trolls" are actually two different kinds of people: the awesome kind, the ones that make a forum lively and entertaining via sarcasm and good humor, and then the kind of people that you'd rather kill than spend five minutes in the same room with them. Y'know, the kind of person who derails funerals for a living, etc. People heckling politicians during speeches are "trolls." Heck, politicians are "trolls" as well. Both kinds of trolls are common among forums, and (arguably) are necessary to a forum's survival.
On a side note, I tried to discover the meaning of (JBHMD)... Google tells me it stands for "Jake Brody Huffs Mad Dong," but perhaps my research did not uncover the correct translation? o_o

There is a troll lurking in everyone...it just takes the right circumstances for it to come out of hiding...
Arch-bishopxc2# is the worst because you introduce a new piece into the game, move illegally*, and falsely claim checkmate.
*Unless your arch-bishop starts on g3, in which case, have fun.

Even better, you can hit your opponent in the temple with the archbishop and claim a win on time 30 minutes later.

I assume that is worst because it allows this, losing both the pawn and the game.
1.f3 looks pretty bad to me.
