Opening choices for different players
Do you tailor your openings for specific opponents? I've found that taking into consideration who my opponent is has really made a difference in my results lately. For instance, if I'm playing a really fat guy I might pull off the Fried Liver Attack.
Yes i do with online games.
I know some sites have a dominant type of player
and those players neglect certain other skills needed to play chess.
This also goes for players that only have mate on their mind
and want to attack the king side. So they ignore everything on the
Queen side.
