1 core each
Permanent brain enabled with the idea of in-directly increase total time each game.
128mb hash each - more than adequate with this relatively slow laptop.

Predicted move ratio = 62%  

Permanent brain wrote:Pondering is less effective than normal thinking. For example, if the program guesses 25% of the opponent's moves correctly, the use of pondering is on average equivalent to increasing the normal calculating time by a factor of 1.25.

In this case the time factor is 1.62.

In chess games between two computers, pondering makes sense only if the competing chess engines use separate processors or cores. If they share the same core, the pondering program steals half of the time from the program thinking in the normal way and uses the stolen time less effectively.
