The very creative Latvian Grandmaster Alexi Shirov has a penchant for sharp opening variations. In particular, Alexi likes to get in g4 as early as feasible. Numerous opening systems have thus been enriched with this approach.
Playing over Shirov’s games from the recent Helsingor International Tournament, I noticed that he has yet another ‘patent’ under review. Take a look at the following game.

1.e4 e6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.g4$5{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>The idea of this move is to immediately start a fight for the initiative. Traditionally, White usually tries to castle queenside and then advance his g-pawn. The immediate g4 creates new challenges for the Black player. Only time will decide on its merits, however.</strong></span></div>
