7.0-0
An interesting pawn sacrifice. The move was introduced by Arnold Denker in 1944 against Rubin Fine.
7...f5
A) 7...N×c3 8.b×c3 B×c3 9.Rb1
White has very good compensation for the pawn. He is ahead in development, as well as in control over the centre. For instance:
9...Ba5 10.Ba3 d6 11.c5
B) 7...B×c3 8.b×c3 N×c3!?
This is very risky, in fact just bad, even though it's the first choice of the engines.

54.Ng4??
Black has already got the advantage, and this move only makes Akobian's task easier.
White could have put up some more resistance with 54.Ne4.

29...a3?
Black should have continued with a waiting move like 29...Qa5 or 29...Qc5.
Now, the Black's queenside pawns have been placed on the dark squares , in the endgame, his bishop won't be able to defend them.

White has put all his chips on the blood red color of the initiative. When you opt for a dynamic advantage over the static (long-term) advantages that your opponent is most likely accumulating along the way you cannot drop your pace. Here White will only just keep an equal game after 14 Ne4, but this move is irrelevant as there is another move that should work – unless White really is worse. But why should White be worse? He is better developed, better coordinated, his king is safer and he has sacrificed nothing thus far.
14.Bf4!
This is the logical move. An inactive piece is brought into the battle, adding to the pressure.
14...bxc3
There was a possible alternative in 14...Nxd5 15.Nxd5 Qxd5 (or 15...exd5 16.Rc1 and White wins material, one line being 16...Ra7 17.Rxe7! Rxe7 18.Qxd5 Bd7 19.Ne5 and Black is busted) 16.Qxd5 exd5 17.Rac1, when White keeps the initiative without the queens. Alternatively, 15.Ne2 followed by Ned4 leaves White with long-term dynamic compensation as Black is uncoordinated.
15.d6 Nd5 16.dxe7+ Qxe7 17.Be5! Keeping up the pressure. It is not easy for Black to free himself.

27.Ra1!
Prevents Nb5. While White has no realistic chances for active play, it's not easy to see how Black can make progress...
27...Rd5!?
Dreev comes up with an interesting plan. The Bf3 is an important piece and winning the exchange will increase Black's light-square dominance. 27...Nb5?? 28.Bd1.
28.Kh2 Both sides ignore the rook for the time being.
28.Bxd5 Rxd5 (28...exd5? 29.e6 fxe6 30.Bxg7+/-) 29.Kh2 is passive but still leaves Black with the task of how to increase his pressure.
