It is called "Tactics Time! 1001 Chess Tactics from the Games of Everyday Chess Players", and contains 1001 chess tactics puzzles all from real games.
There are a bunch of games in there from RHP players.
Most of the games are from players rated below 2000.
Each problem gives the name of the players, their rating, and where it was played. None of the problems have been used in other books before, so they are all new problems.
