Does this opening have a name.

I've seen young beginners play it quite often, it's how they think they should develop their Rooks.  It's easy for black to stop  by moving the e pawn and threatening Bishop x Rook if he moves it to a3. 

I don't believe it has a name it's so stupid and noobish. The highly rated player was probably just playing a kid and having some fun. 

Not sure why any highly rated player would play that. However, you're not gifted with many opportunities to seize the centre so easily. The perfect pawn centre is pawns on d5 e5 as black. Personally, i'd play d5 then e5. e5 pins it. so play d5 and lure the rook out, it's what your opponent wants anyway, so you can be sure he'll play ra3. an isolated rook presents no problem without its army. it could become a target for tempi depending upon placement. It's rare black will ever get that opportunity. e4d4 is more common as white plays first. normally with d4 or e4, but exchanges can also end in that position.

It's called the Kangaroo opening. It's tricky but playable.
