Here is a recent game I saw at the e2e4 Dublin International masters this month.
It was round 7 crowd pleaser.
4 pawn attack with the extra pawn push sac. after move 12.
1.d4 Nf6 2.c4 g6 3.Nc3 d6 4.e4 Bg7 5.f4 O-O
6.Nf3 c5 7.d5 e6 8.Be2 exd5 9.cxd5 Re8 10.e5 dxe5
11.fxe5 Ng4 12.e6 fxe6 13.d6 Ne5
both sides are fully commited - not to material but space and the initiative.
14.O-O Nxf3+ 15.Rxf3 a6
(15...Nc6 16.Ne4 Bd4+ 17.Kh1 Bd7 18.Bg5 Qb6 19.Bf6 Rf8
20.Qd2 Rf7 21.Bxd4 Nxd4 22.Rxf7 Kxf7 23.Rf1+ Nf5 24.Qc3 Qd8
(25...b5 26.g4 Qh8 27.Qxc5 Rc8 28.Qxa7 Ke8 29.gxf5 exf5 30.Bxb5

36.c8=Q+ Ke7 37.Qe6+ Kd8 38.Rc1 hxg5 39.Rc8#)
26.Rxf5+ exf5 27.Bc4+ Kf8 28.Qh8#)
16.Be3 Nd7 17.Qd2 b5 18.Raf1
(18.Nd5 exd5 19.Qxd5+ Kh8 20.Qxa8 Ne5 21.Bxc5 Nxf3+ 22.Bxf3 Qh4
23.g3 Qc4 24.Qc6 Rf8 25.Be3 Qd3 26.Bf4 g5 27.Rd1 Qf5 28.d7 Bxd7

(19.R3f2 c4 20.Ne4 Bb7 21.Nf6+ Bxf6 22.Rxf6 Bd5 23.Bd4 Qxd6
24.Qg5 Nd7 25.Rxg6+ hxg6 26.Qxg6#)
19...c4 20.Bh6 Qd7
It was more important for black to preserve the dark squared bishop.
(20...Qb6+ 21.Kh1 Bh8 22.Qf4 Qxd6 23.Ne4 Qe7 24.Bg5 Qf7 25.Qh4 Qc7 26.Nf6+ Bxf6 27.Rxf6 Re7 28.Bf4 Bb7 29.Qg5 Be4 30.Bxe5 Qd7
31.Rh4 Bd3 32.Rxh7 Rxh7 33.Bxd3 Qxd3 34.Rxg6+ Kf8 35.Qf6+ Ke8
36.Qxe6+ Kf8 37.Rg8#)
21.Ne4 Rd8 22.Bxg7 Qa7+ 23.Kh1 Qxg7 24.Nf6+ Kh8 25.Rxh7+ Qxh7
note how every white piece has joined the attack and black still has major material undeveloped.
26.Nxh7 Kxh7 27.Qg5!
It is extra important to continue to grab the initiative and not allow the opponent back into the game.
Rg8 28.Qxe5 Ra7 29.Rf3 Rgg7 30.Rf8 Ra8
31.Qg5 Rg8 32.Qe7+
The following would have been more elegant:
(32.Qh4+ Kg7 33.Rf7+ Kxf7 34.Qe7#)
Rg7 33.Qh4# 1-0
At no stage does white deviate from the central plan or look for material advantage. One of the few games where there was no conflict in my mind as to the objective - to win.
