Thank you very mutch for your evaluation, ideas and analisis. That game was played today against G.M. Sareiwan into playchess. I have played just a few against strong chess players. I would like to play against GMs and try antichess. All my life playing engines, have been an interesting experience, but to play GMs just a dream that I would like to see into the really life. Best, Pablo
