Hou Yifan plays the Fool's mate. Resigns after move 5 in 2017 Gibraltar Masters.

Speculation is some form of protest? No idea, really.

No, it was just an opening preparation mix up. She chose a weak opening and misremembered her preparation.

It will be interesting to hear her reasons.

At least she got some extra rest between rounds.

She'd have done better with the Bongcloud Attack.

I see that too but it doesn't makes sense. Why drop a game against a male player, play to win to prove you should be playing against more men.

Drop a game against a woman player (although if you are trying to prove that men and women are equal then it should not matter which gender you play).

Still makes no sense, it is a silly way to protest. Walk out of the whole tournament then. But to purposely drop a game to a male when you want to play against men?

Prove you should be playing against men by beating him, not using a stupid opening to drop a game on purpose. 

The pairings are all computer generated genius.

As far as I know, FIDE pairing rules are pretty strict unlike in the USCF where the TD can get away with a lot, basically changing the pairings however they please.

If the pairings were tampered with I think it would be obvious to people who are familiar with the rules.

On a different note, her status as female world champ has, I think, gotten her some invites to super tournaments. In my mind she's already privileged due to her gender so this protest, if it is about having to play women, comes off as childish.

If it was a protest then 3. d3 doesn't make sense. Why not do something that simply allows Qh4 mate? Then it can be more clearly construed to be a protest. With 3. d3 it's beginning to look more like you've buggered up an attempt to surprise your opponent with a more outlandish opening.

Maybe she was pissed that Magnus was hogging all the attention with his screwups.

Not sure if you're joking, but the first two moves are so intensely bad that there's really only one interpretation.

I was half-joking but 3. d3 does look a bit odd if you've really decided to jump off the cliff.

If you're going to jump off a cliff, might as well laugh on the way down I guess

Wow, this is not a joke...

Yes, but a3 would have been even more of a protest. 3. a3 Qh4#

d3 gives the K an escape square, almost as if she was trying to salvage something.

What is not a joke? The game , the protest or jumping off a cliff?

The way I imagine it, there were multiple non-verbal exchanges between her and her opponent during the opening sequence. 1.g4 is already disrespectful. Then, avoiding the mate with one of the worst ways to do it, d3, is like icing on the @#$@ you cake. It's like saying I'm not taking the game seriously, and I might make you play 20 or 30 moves. Who knows. Then she resigns after move 5. If anything, to me it seems like she was really pissed, not that she suddenly decided to not lose.

Hou Yifan's opponent, GM Lalith, after the game at #gibchess. He thought 1. g4 was preparation until he saw 2. f3 he told @chesscom.
