The exchange variation to me seems kinda easy for black to equalise but to someone with a certain style of chess this can be favourable for them. White's idea is to exploit his first move in a roughly equal position, he also has chances with a minority attack on the queenside.

Playable but I don't see the reasoning behind the move, perhaps to get a grip on e4? if so then Bf5 is easier to acomplish this.

This pin however is different to blacks pin. The pin is now hard to escape as h6, g5 leaves the kingside horribly weak. White on the otherhand can chase the black bishop without weakening his kingside and seeing as b4 is a move he wants to make anyways he can now make it with tempo. An alterniative was Bf4.

c6 is by far the better move. Now the c pawn does nothing on c7. Bf5 and Nbd7 is better.

The pin was annoying but Qd6 is just a waste of time, Bf4 can now be played with tempo

Okay, not entirely sure of this. The bishop doesnt really do much does it? I mean if the pin is annoying then 0-0. then again there is nothing entirely wrong. Ba5?! is dubious ie b4 Bb6 with doubleing on the c file and then playing b5! or else white can just place his knight on c5 and strangle black because b6?! makes the queenside horribly weak.

Basically forced and white is left with the two bishops in a nice position, with a queen and knight misplaced. Right now I feel like playing 0-0 and c4 making use of the fact that black's knight on c6 deprives the d pawn of proper protection (c6) if black takes then the e and d pawns will decide the game (pawn roll) blacks only hope seems to be a regrouping of Ne7 and c6 when Bf4 Qe6?! (if black doesnt wanted doubled f pawns and Ne5 is simply overwhelming.

10...Bf4 at once might have been worth a look. But I probably would have gone for for the text line myself.

I like Bf4 although Ion likes the text I think that Bf4 and Qc2 has more chances for opening the centre. White's plan is either to play Bf4, Qc2 Nd2! f3 e4 or instead of playing for e4 then c4 to undermine the weak knight. (Sure the knight after Bf5 is safe but the d pawn then becomes a problem.

I wish I could spot these intermediate moves OTB  

Blocking in your own bishop must be bad. Qe7 is more logical but still white has all the chances. Plans like c4 d5 come to mind with the possibility of getting the Be5 and Qc2-b2. Of course this would be if white was dreaming and had as many moves as he liked but even still c4 0-0 and rooks on the files when black has no counter to the pawns. Of course you have the move the knight first...

Interesting but I feel this is slightly not what the position demands. Doesn't everything hold after Re8 or Qf5? The h7 square is covered and white has little attacking chances...

!? An interesting move, white declines the pawn and goes for the king. However, doesnt Qf5 again hold?

White has an enormous game. Even aside from tactical considerations, look at that central pawn mass! Black has nothing to oppose it...

h4!! hxg hxg is great for white.

I can't see anything better than 16...Qf5 for Black here.

Thats not a sac its an investment.
