The Open Games Powerbook 2014

The numerous possible transitions make it only logical to bring together in the large Open Powerbook 2014 all the other open games (except the Ruy Lopez). It will consist predominantly of engine games (195 000), with in addition top class material from Mega (23 000) and a small number of correspondence games (1000). This allows one to make interesting comparisons: is the Scotch "better" than the Italian? Or is one better trying the Four Knights Game straight away? And how should one continue? Instead of 4.Bb5 it is also worth considering 4.d4 and 4.g3, but in the Powerbook it is 4.h3!? which comes in second position with a sensational 8500 games and a result of 58%. Some completely original theory has been developing here, along the lines of 4...Bb4 5.Bd3!? and later a3 intending dxc3 or b4, so as to then develop the Bc1. Such discoveries make it easy for you to fashion some surprise weapons for your own repertoire.
