Kibitzer's Corner
Feb-29-04  ConLaMismaMano: Oswaldo Zambrana (2404) is an FM or IM? He is from Bolivia, the strongest player of that country, i believe he is an aggressive e4 player.
Sep-29-04  alexandrovm: Oswaldo is from my country. He is an IM. He is trying to be a GM. He has just made his first GM norm (1 out of 3) some weeks ago, in a Sao Paulo chess tournament, category XI I think. I'll try to get this games from my computer so I can send them to this database.
Dec-08-05  alexandrovm: Congratulation to Oswaldo Zambrana because he got his 3rd GM norm a few days ago. He will be next year (because he made his 3rd GM norm but needs 2500 ELO at least, he has 2430 right now) the first bolivian chess player to have a GM title. Links:
Feb-17-06  BIDMONFA: Oswaldo Zambrana


Jan-01-07  alexandrovm: he finaly and officially got the GM title, congratulations Oswaldo!
