Help Identify Chess Structure

Chess Structures by Mauricio Flores Rios Level 2. Puzzle 8. Leitao - Robledo, Mar del Plata 2009

Can someone let me know which structure this is? For some reason it's not easily identifiable to me.

Pawn Structure #2 by Rios: Hanging Pawns. It means that white's (or black's) pawn structure has an island, formed by 2 pawns. Example:

I don't think that's it. You may have been looking at an adjacent puzzle. I think this one has a pawn on the b file, and no black pawn on the e file, but it does have a pawn on the c file I think. And I think also a white pawn on e4 maybe. Don't have it in front of me though.

Leitao - Robledo, Mar del Plata 2009, was a classical fianchetto King's Indian with exd4.

I believe the structure of this game is an Open Kings Indian Defense (According to the classification of the book). Thanks for the help.

Yes, it's a King's Indian type formation, specifically, a Boleslavsky Wall.

Thanks for the additional terminology. Soltis' book has more of the cute names (Can't remember if it discussed the Boleslavsky Wall. It gets a little confusing because I know there is at least two pawn structures, maybe more, named after Boleslavsky). Rios book doesn't really bother with it.

cool

Yes, you are correct, Soltis' book has a section on it, but he says the term came from Kmoch, the author of another book on pawn structures.
