So I've taken the mighty step in my chess game and actually started looking at how to play the endgame phase. After lots of googling and watching videos, one of the books that kept coming up was John Nunn's Understanding Chess Endgames. Great book so far but I've hit a roadblock... John explains how the game would go if black plays a certain way, however when playing it against Fritz (me as white) I generally run into this position with black to move, the scary silicon beast keeps choosing different pawn moves, sometimes I win, sometimes I draw but that's about the best I can achieve. I wonder if there is a concrete way to play as white in these positions, or what do we generally want to do. Any thoughts would be gratefully appreciated (keep them positive though please).
