  - simple quiescence search (no see pruning)
  - simple 4-bucket hash table (no ageing)
  - simple evaluation function with knowledge limited to material, positional and tempo (no pawn structure, mobility, king safety, imbalance, trapped pieces, ...) tuned to probably suboptimal coefficients.
- - simple (insertion) move sorting: hash move + mvvlva ordered capture/promotions + quiet moves (no killermove, no history)
- - null move pruning (no lmr, lmp, razoring, frontier node pruning, ...)
- - checking move extension
