After Nc3 ....d5 tempts the knight into an exchange where black would clearly have the advantage as d5 is protected by the Queen.
e4 challenges blacks right to the centre. An exchange here would put black at a disadvantage. Black could have defended d5 with Nf6 but chose not to. Instead black chooses to exchange pawns on e4.
After Nxe4 and Nf6 I believe white is disadvantaged here. White has the option of retreating to a safe square or defending the knight.
After the exchange of knights on f6 black has doubled pawns and because of this I believe black is slightly disadvantaged. So on this basis I would prefer to be playing white. Also black has an open g file it has to defend and then an isolated h pawn.
I'm not a very good player and make lots of errors so I hope this makes sense.
Let us add an irregular line to the forums:
After the following:
1) What do you think should be the ideas for black & white?
2) Which side do you prefer? (please add your reasoning)
