Answers.Body: <p><em>The</em> special feature of a 1.e4 repertoire is that transpositions are rare. You can have independent repertoires against each of black's replies. This is very different from 1.c4, 1.d4 and 1.Nf3 where moves can often be played in many different orders and you always have to watch out for transpositions between your various lines.</p>
  <p>Then these are the &quot;big four&quot;:</p>
  <p>1...e5 -- The Open Game</p>
  <p>1...c5 -- The Sicilian</p>
  <p>1...e6 -- The French</p>
  <p>1...c6 -- The Caro-Kann</p>
  <p>Most of your time should go to those, especially the first three (the CK is also very good but not as popular at amateur level).</p>
  <p>Then there is the rest, like</p>
  <p>1...d5 -- the Scandinavian</p>
  <p>1...d6 and 1...g6 -- the Pirc and Modern (there are transpositions between those)</p>
  <p>1...Nf6 -- the Alekhine</p>
  <p>And other lines that you can skip for now.</p>
  <p>The reason for this is that 1.e4 puts an undefended pawn in the center, and the intended follow-up 2.d4 is hard to prevent as it will be defended by the queen. This is different from 1.d4 where 2.e4 is easy to prevent. That means all replies must immediately have some specific way to deal with that, and the different ways of doing that immediately prevent transpositions.</p>
  <p>1...e5 -- black just does the same. 1...c5 -- black will exchange his c-pawn for the d-pawn if it arrives on d4. 1...e6 and 1...c6 -- black will also put a pawn on d5. 1...d5 black immediately puts a pawn on d5 but can't recapture with a pawn. 1...Nf6 -- black attacks the undefended e4 pawn. 1...d6 and 1...g6 -- black lets white play 2.d4 and intends to attack the center later.</p>
  <p>Hope this helps.</p>

Answers.Text: @AmlanSahaKundu: that's for you to figure out. If you decide you want to play 1.e4 e5 2.Nf3, and then go for the Scotch gambit if black plays 2...Nc6 by 3.d4 exd4 4.Bc4, then one of the things you need an answer for is 4...Nf6. Apparantly the "Nakhmanson Gambit" (never heard of it, doesn't seem like a good idea, but OK) would involve playing 5.0-0 there, and if black takes the pawn with 5...Nxe4 then you'd play 6.Nc3?! and apply your knowledge from there. But there are also other options at every move that you could also think about what you'd play if you met them in a game.

And, the beauty of this gambit is: since it is quite uncommon, players (even 2000+) did easily fall into the deadly trap. That's why I am trying to cover such deadly lines into my repertoire.

  *The* special feature of a 1.e4 repertoire is that transpositions are rare. You can have independent repertoires against each of black's replies. This is very different from 1.c4, 1.d4 and 1.Nf3 where moves can often be played in many different orders and you always have to watch out for transpositions between your various lines.
  
  Then these are the "big four":
  
  1...e5 -- The Open Game
  
  1...c5 -- The Sicilian
  
  1...e6 -- The French
  
  1...c6 -- The Caro-Kann
  
  Most of your time should go to those, especially the first three (the CK is also very good but not as popular at amateur level).
  
  Then there is the rest, like
  
  1...d5 -- the Scandinavian
  
  1...d6 and 1...g6 -- the Pirc and Modern (there are transpositions between those)
  
  1...Nf6 -- the Alekhine
  
  And other lines that you can skip for now.
  
  The reason for this is that 1.e4 puts an undefended pawn in the center, and the intended follow-up 2.d4 is hard to prevent as it will be defended by the queen. This is different from 1.d4 where 2.e4 is easy to prevent. That means all replies must immediately have some specific way to deal with that, and the different ways of doing that immediately prevent transpositions.
  
  1...e5 -- black just does the same. 1...c5 -- black will exchange his c-pawn for the d-pawn if it arrives on d4. 1...e6 and 1...c6 -- black will also put a pawn on d5. 1...d5 black immediately puts a pawn on d5 but can't recapture with a pawn. 1...Nf6 -- black attacks the undefended e4 pawn. 1...d6 and 1...g6 -- black lets white play 2.d4 and intends to attack the center later.
  
  Hope this helps.
