====== Chess - Programming - Ponder ======

Ponder refers to thinking in the opponents time:

  * To use the opponents time, to continue searching the tree and store the information in a large lookup table for later use.
  * This will save time when its our turn. 
  * Requires transposition tables.

----

While the opponent is looking for a move, instead of sitting idle, guess their most likely move and start analyzing the resulting position.

  * If we guess right, we have a head start searching;
  * if we guess wrong, we have wasted no time and will have at least somewhat populated the transposition tables.

More useful against humans, and engines running on separate machines.

  * On the same machine, each engine will disrupt the other with their pondering efforts, resulting in a lot of noise.
