selecting candidates


One of the aspects in the playing process is the selection of candidates to evaluate.

Selecting candidates in the opening  

Black to play. Depending on Black's strength, intuition and preferences, the candidates may be as many or few as these 10. A professional player may consider fewer. Leela Zero in this position evaluates all these moves, except d and h.

Selecting candidates in the opening  

These are the first 10 candidates evaluated by Leela Zero after B1. Traditionally, human players have been evaluating the approaches at a and b, or a wedge at the bottom. The latter has gone out of fashion.

In the middle game, there are usually a few or even a single hot positions, so that the candidates are reduced to plays that locally deal with the situation.

In the endgame, there are again multiple candidates to evaluate in different areas of the board.

Techniques for selecting candidates

Candidate selection is an intuitive aspect of the game, or network bias in AI terms. We don't evaluate all empty points. With knowledge of basic technique and strategy, the number of candidates is reduced to a few.

Certain techniques can help finding more or better candidates:

  • the enemy's key point is yours: when you find that the opponent's response to any of your moves is often the same move, then that becomes a good candidate to evaluate for yourself
  • one two three principle: when you visualize a sequence, e.g. as Black, B1-W2-B3, where B3 is a good move after the B1-W2 exchange, it's a good idea to evaluate what happens if you play B3 right away
  • tenuki is always an option: when none of the moves you have evaluated in a certain area or position give a satisfactory result, then you may consider playing elsewhere
