"... How often should you play? If you are trying to improve that means as often as you can, but playing lots of slow games can be tiring and time consuming, so most people are not able to play an OTB tournament every weekend even if one was available down the block. A minimum of 8 OTB tournaments and about 100 slow games a year is a reasonable foundation for ongoing improvement. ..." - NM Dan Heisman (2002)

"One of the great things about chess, as opposed to disciplines such as ballroom dancing, is that you can learn a lot from the right books. ..." - GM Nigel Davies (2010)
"The way I suggest you study this book is to play through the main games once, relatively quickly, and then start playing the variation in actual games. Playing an opening in real games is of vital importance - without this kind of live practice it is impossible to get a 'feel' for the kind of game it leads to. There is time enough later for involvement with the details, after playing your games it is good to look up the line." - GM Nigel Davies (2005)
"... only a good balance of theory and practice yields steady improvement. ..." - NM Dan Heisman (2002)
