My first impression is that there are 3 types of skill needed:
- The first 10-15 moves are usually right from the book.
- Simple positional moves follow.
- Then tactical skirmishes are fought out
The middle skill, seeing simple positional moves à tempo has drawn little attention. Yet such moves form the meat of blitz games. Everyone who has ever played in a simul probably agrees, you are outplayed by simple logical moves, not by genial strategical concepts or tactical brilliancies. Just by sound moves and LPDO.
Our 2100 rated clubchampion and I don't differ all that much in tactical ability. But his ability in the complex middlegame to steer away from complications to a favourable endgame is unsurpassed.
