[surjjhep] beginner chess

1. checkmate opponent (mate in 1).
2. avoid mate in 1.
3. take opponent's free pieces.
4. don't hang pieces.

beyond this, you are no longer a beginner.  tactics that win or lose, or win or lose material, over many moves are beyond beginner.  if you are a beginner, don't fret losing or losing material to more complex tactics.

this is equivalent to a chess engine at 2-ply depth and very simple evaluation function.  maybe 3-ply to determine "don't hang pieces".

can intermediate chess be similarly precisely defined?

beginner volleyball strategy: hit the ball over the net whenever you can, as soon as you can.
