A Rook and Pawn endgame from my daily practice on ChessTempo.com. These are endgames which gave me trouble during the practice. I broke them down into steps to help remember them and post them to share with my fellow chess players. The solution is the shortest as verified by the endgame database. Comments are my own.
In the practice, I had got the first move correctly, but moved Ra1 with the idea of Rh1. This was the right idea but didn't have the tempo saving of Rg7+.
Yesterday I had decided to review Pandolfini's Endgame Course. A large percentage of the daily puzzles have been Rook and Pawn vs. Rook endgames, which Pandolfini covers well. The idea for solving today's puzzle is the same as Pandolfini's Endgame #198.
