How to decide whether to play e4 or d4

LMAO  So, for U, the mathematics don't make part of the Science ?!? 

So I can think of any 2 terms and apply a condition of the both of them,and play e4 or d4 based on if the condition applies to the 1st term or 2nd term?What if the terms are said in a different order?Or wait,maybe what u said is like rolling a 2-sided dice.Well,in that case i guess that would make sense.

I guess that's a useful comment.The others kind of joked around as religion and school don't have a lot to do with chess XD

OK I agree u all ..its wright but mine is not bad ...,u all are wright but I step ahead

I guess you do have a point.As I mentioned before it's like rolling a two-sided dice,so I can try yours.

e4 is for the young. d4 is for the old.

e4 is for the restless. d4 is for the patient.

e4 is for the brash. d4 is for the subtle.

When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me. Until I read an offhand quote from Bobby Fischer.

"Best by test!"

"BEST BY TEST, EVERYONE!"

"BEST BY TEST, BOBBY FISCHER SAID IT"

Well,I guess you should try going to the forum called "d4 players lazier than e4 players".Perhaps you can discuss this on a more active forum  I personally don't see much difference between them but it really seems like a controversial topic as I can tell by your exclamation marks,capital letters,and bold text.Just don't get too excited XD

I do not understand how the rapid-assault nature of the Queen's Gambit (one of the most notorious and common follow-ups after 1. d4) is for the patient.

The very definition of Queen's Gambit is gaining a large pawn center for a rapid developmental advantage. Sounds very impatient in nature to me.

Flip a coin so your opponent will not know ahead of time which move you will play....

Don't know why this is a constant topic for discussion, there's nothing wrong with either opening option. Try playing both and see what middlegame positions you arrive at, see what you're happier and more comfortable with. I personally play 1. d4 because that's just where I started learning, but I plan to know some e4 openings too at some point.

I am a d4 player,sometimes I switch it up to c4 when I'm bored to death, I personally don't like e4 games. d4 leads more than often to positional battles (but also into sharp lines and the same goes for e4). Just stick to one of the two, it's more important to train lots of tactics, refine endgame technique and get a good grasp on positional chess so that you can play any position

now tell ur repoirtoire what u play e4 or d4 just say the first move fast

now tell what u like me e4 I d4 .,...just mention the first move

I agree it's a generalization. Not sure the Queen's Gambit is the best example, though.

The vast majority of Queens Gambit games are declined in some fashion, and usually boil down to strategic ideas like playing against an IQP. It does not typically elicit images of quick checkmates and double-edged miniatures. When I play against he Queen's Gambit, I do not get the feeling I am going to be blown away by a "rapid assault". Contrast that with the most direct E4 equivalent, the King's Gambit, and you can probably better understand the general point.

Now there is something to be said for the Blackmar-Diemer gambit (a d4 opening) vs. the Center Game (an e4 opening), but then neither of those openings are very mainstream.  I feel like we could go pretty far down the rabbit hole, but the point is that if you like sacrificing on f7 and hoping to end the game in 15 moves you are probably not playing 1. d4.

All chess games involve tactics sooner or later; that is the nature of chess. 

But I play 1.Nc3, so whatever.
