I'm 100% a Knight man.
The amount of games I have won because someone once said
Bishops are better than Knights is incredible.
They never swap a poor Bishop for an excellent Knight. Never.
Bishops are better than Knights if you are over 2200.
"What's good for over an 2200 player is not necessarily good for weaker players."
It's not the exact quote - but it's close enough. J.Rowson in Zebras.
Which translates, certain positions are good because good players
can play them. Give the same position to a weaker player and
they will screw it up.
If you only study one theme on the middle game make it building
and securing Knight outposts.
Blitz Tip No.15
If your opponent has a roving Knight and you don't want to walk
into a Knight fork. (who does?).
Instead of wasting precious time working out where to go ot avoid forks.
Place the King on the same diagonal one square apart from the Knight.
Thus.
The Knight now needs three moves to deliver a check.
