It’s White to play here: would you trade rooks or keep them on the board?
I was Black here in a ‘slow’ rapid game from an internal club online tournament. I’d blundered early on in aand had been lost most of the game against my young and inexperienced, but talented, opponent. He played for this position, presumably thinking the pawn ending was won: he’d capture my queenside pawns and win on the kingside.
The game continued:
Moving the rook away would have led to a level ending.
As we were playing a relatively slow time limit I was able – because I knew the classics – to see the idea here and calculate that it really did work. The immediate 41.. a4 also worked.
42. gxf5 a4!
43. f6 leads to the same sort of thing
44. bxc3 b3!
45. axb3 a3!
Although I now have two pawns against four, my a-pawn is going to promote.
Not so hard if you know the 3P v 3P breakthrough: featured in most ending books, including.
