MIG-64 - 64 most theoretically important selected games from TWIC, 

In the first instance, I have chosen games containing the most valuable novelties in topical variations. 

“Level 2” – these are novelties in l;esser variations or novelties of arguable merit in topical variations 

“Level 3” – non-standard, original opening ideas.

At the highest level, "an important novelty" often doesn't mean a single move, but the mere fact that a top GM chooses a forgotten or underrated variation. I have included the most interesting such games in MIG-64.

The opening analysis of games is done mainly using Mega Database 2012, TWIC and Correspondence Database.

All games in the file MIG-64 consist of express-commentary, including:

1. indicating the critical positions, at which the "independent" stage of the game starts, ie, the part which does not have exact analogues in the past; 
2. information about the continuations previously seen in critical positions;
3. a preliminary assessmernt of the new variation.
