If I have the correct picture, you mean that all other pieces have been exchanged but the rooks? My first thought in this kind of scenario isn't necessarily to exchange, but perhaps a semi-lift with one rook and anchor it to a pawn if you can so you can threaten to double rooks on the file. This action usually results in the opponent getting nervous and initiating the exchanges.
Remember to bring your King closer to the open file though so he can keep an eye out in case any passed pawns get created.
I need info on what to do with this scenario. (encountered 2nd time this year):
7 v. 7 locked middleish pawns, open g file I control at Rg8,--- K,R,R each player's own side. Looks like who ever attacks ends up down a rook. I have no idea what I am suppose to do. Do I even want to get behind opponents pawns ??? With 1 Rook or 2 ???? What is the way forward ???? Should I stay on my own side ??? Any online games of GMs like this or other info. ??. What is my positional goal suppose to be ???? I almost always can find a way forward but this is one of the few that has me stumped !!! Clueless !!!! Thanks for any suggestions.
