Qh7# How about an algorithm which works like the current one in sound captures (non-sac or Rebel assumes the capture) but if the capture is an obvious sacrifice Rebel will think the next move longer. I know mistakes done by bad players will also be thought longer but I don't think that it will be a negative thing.. at least they have more time to take the bad capture back before Rebel punishes them :) and the important point: This will prevent GMs and other strong players to set up traps like this. I don't think that the game shown below is a big expection.. there are many anti-computer lines like that. This algorithm would also be more human-like an approach. Any strong human player will think hard after such a sacrifice to find out possible counter- attacks or traps. regards, -- Jari Kylmälä
