From what I know I would say this:
A.'''''''''''1.Nf3'''''''''''
Common if you sometimes play
i)******1.Nf3 ... 2.g3 ... 3.Bg2******
and , then white can play on move four things like 4.d3 ; [b]4.d4 transposing to a catalan
or similar ;
4.c4 keeping options open for where to put his
e-pawn his b-pawn , you could say that this is 'the english'. Perhaps white plays something like 'botvinnik variation of english' [botvinnik setup]. Botvinnik setup is basically that white plays a classical kings indian setup but with d-pawn on d3 instead of on d4. ;
4. other moves for white or
ii)******'kings indian attack'****** or
iii)******'reti like openinges'*******
{ such as the lines, 1.Nf3 Nf6 2.g3 d5 3.b4 , 1.Nf3 Nf6 2.g4 }
B.'''''''''''1.d4'''''''''''
White has options to play [what you could call]
sharper against black. The QGA. 1.d4 d5 2.c4 dxc4 3.e4.
Moving Nc3 out before Nf3. But! Now white must be prepared against 'Nimzo indian' which some choose to avoid.
If 1.Nf3 ---- this [almost] mean that ---- white has QID in his repetoire but not Nimzo (some simplification here) ----- and ----- white choose to meet slav with Nf3 lines ------ and ----- white choose to play a classical set up with Nf3 against QGA. ------ and ----- if black want to play other lines like 1.Nf3 c6 .... or .... 1.Nf3 e6 ..... or ..... 1.Nf3 d6 ----- then ---- white has restricted his [what you could call sharper] alternatives. The ones where white plays f3 early comes to mind.
But I am an amature player. By that I mean. I could be a little inaccurate in the details here. // the viking.
