Profit from opening mistakes- 4

Looks like a London System pattern! That is what I thought during this Bishop's Opening game. Lots of players make the mistake to trade quickly for no apparent deep reason, like in this game. Let's have a look.

So, what is the similarity with the London System ?

In the past I played stuff like this, with the idea to strengthen the center with an extra pawn, and get some play over a semi open g file. A bit risky sometimes, but ... fun ! :
