Based on a good 330 000 games, of which roughly 10% were played by humans, this powerbook brings together the related areas of the Slav and the Semi-Slav. Interesting statistical conclusions can be drawn, because where there may only be a dozen games known to human theory, powerbooks can frequently have access to numbers as high as the thousands.
For the position above Mega has 21 games, and in addition there are a few correspondence games. As the graphic shows, the powerbook is based here on more than 16 000 games. If Black plays 12...h6, White scores 53,7%. One should also keep an eye on the two numbers which come after that. The engines or humans who had Black have an average strength of 2577, but their performance was only 2539. Naturally there is no guarantee that these numbers will remain in the lower range.
The Slav/Semi-Slav powerbook is perfectly suited to the brushing up and extending of your own repertoires.
