Attacking and defending done badly

Steinitz taught us:

  • If you're attacking:
    • Don't attack too soon
    • Attack with a team
    • Attack only if you have good reason=you have an advantage
  • If you're defending:
    • Defend what you have to
    • Don't make weaknesses

Let's see what happens if you break the rules...

  • Attacking done badly
    • Too soon
    • Too lonely
    • No excuse
  • Defending done badly
    • Missing threats, opening lines, going quiet

{Outrageous!  But how can White show Black has made a mistake?
Well, Black is looking at the side of the board, so White opens up lines in the centre for their better-developed pieces.  That means aiming for e3-e4, and that means playing f3, and that means moving the Knight to cover e4}
