1. e3 !?

Interestingly, 1. e3 is the third most played move on chess.com according to the Game Explorer: http://www.chess.com/explorer/index.html?db=2

Since when did e3 become popular?  I suppose one could play a reverse French Defense (1. e3 e5 2. a3 d5 3. d4) or a game could transpose into a queen's pawn opening with 1. e3 d5 2. d4.  Can anyone shed some light on this?

I checked it out. Black's most common response is 1...e5. After that, white's two most common second moves are 2.Qf3 and 2.Bc4 (while 2.Qh5 is 5th most common). So, it seems that the majority of games beginning 1.e3?! are games where white is played by a beginner going for a variation of scholar's mate.

Other things of note here: with 1.e3?! black wins 57% of the time - and if black replies 1...e5 or 1...c5, black wins almost 2/3 of the time. Even if you look at master games beginning 1.e3 black wins amost 50%.

Why would anyone want to open like this? I don't know. Seems like at best it just wastes a tempo, since white normally wants to play e4 at some point anyway. Although I guess you're right that it could transpose into some 1.d4 opening. But then, why not just open 1.d4 in the first place?

my dad played 1. e3 at 2200~ level twenty years ago.  he used it to transpose into a colle or stonewall or queens pawn game, and tried to confuse black on the first move with it.  i think he did it mostly as a novelty though, he usually opened 1. d4 and then played e3 later. 

i really cannot believe e3 is the third most common opening on this site though.. 

I tried 1.e3 e5 2.Qh5 Nc6 3.Bb5 at a coffee shop today several games and it worked out great.

yeah maybe e3 will end up as a d4 opening except if black plays e5 first

1 e3 ?!  isnt a very good move for white and allows black easy equality at the least.

1.e3 allow to Black to play everything what they want, but White still ahead on what Black to trying accomplish!

Black not equal, yet, after 1.e3!

 Your claim is not supported by practice. White scores less than 50% after 1 e3  according to my database.

My claim is supported by my practice.

 Your practice ? The practice of a weak player against even weaker players proves absolutely nothing.

as well as your practice proves nothing...

 I am not the one claiming my practice means anything, you are. Try to pay attention. My claim is based on over 1000 games with 1 e3 on my database which is chess assistant. I have not made any claim that my practice means anything but you have , and that's just silly.

I am leaving your bad epithets on you...

I thought you had me blocked anyway ?  When/why did you unblock me ?
