Hi Álvaro, I've done things like that, except I didn't use games by strong computer opponents (none existed at the time), so just human amateur games. In my experience the critical part is in learning about life & death. Once you have that, estimating ownership is fairly easy, asymptotically reaching near 100% prediction accuracy toward the end of the game. See the following papers for more details:

Thanks Petr & Michael!
