I couldn't find that exact position. Maybe someone with a bigger database can locate it. The pawn structure with pawns on c4 and e4 are known as a Maroczy type position. I found many games with that exact pawn formation but with different piece placement. it was usually reached through some variation of the Sicilian or English although I saw a few that reached it from a 1.e4 e5 king's pawn opening.
I'd guess that it's a fairly legitimate, but not very common opening position.
Here's a short blurb from Wikipedia:
"The Maróczy bind is a formation White may adopt against some variations of the Sicilian Defence. By placing pawns on e4 and c4, White slightly reduces his attacking prospects but also greatly inhibits Black's counterplay."
I came across a pretty nice chessboard wallpaper recently, but I couldn't quite identify the position featured in it...as far as I can tell, it looks like this.
Out of curiosity, does anyone happen to know whether this is a legitimate opening line, or whether the maker just threw some stuff together? It seems somewhat plausible but the pawn structure and the bishop's position look a bit unusual.
