Up to the early 1980s he would try to develop rapidly even at the expense of creating thin positions. He usually became involved in running fights with a number of weak groups under attack.

As his career progressed his territorial style grew to encompass a more steady, slow-paced game; and as he learned to split the game up into a number of smaller fights and skillfully coordinate them his play developed new depth.
