I'd say my win/loss/draw rate there is probably about 20/30/50 percent, respectively. However, on Mobialia, I am quite hard-pressed to beat the phone at ELO 1000.

After several games my ELO rating is somewhere around 1300. Ed Schröder ELO 6 42 Revelation Hiarcs 13. Before you play in a tournament, you want to make certain that your opening arsenal is sound and contains the very best possible moves in your favorite openings.The same is true when you buy a book on a specific opening.You may need to make certain that the main lines are strong and that the analysis given by the author is correct.I have seen too many opening books with sloppy analysis and weak main lines get touted by their authors as being a great surprise weapon.I have all 13 volumes of Secrets of Opening Surprises and most of the Dangerous Weapons series and after losing many games discovered that much of the analysis I had relied on was very poor,(The chapters written by John Emms, Richard Palliser and John Watson are usually excellent, but unfortunately not every author is as consciensious as they are) as well as some of the main lines.With Houdini (ELO 3200)one can double check all their favorite openings and novelties before using them in an important tournament.(Deep Rybka 4 and Deep Rybka 2011 are only ELO 3150)Let me know if there is a particular variation from an opening book that proved to be unreliable, so that others may avoid that particular book , and I can also check the variation first with ECO 'A: through 'E' to see if any improvements can be found. This brought me to the question of how accurate it is.
