Sep-07-15  diagonal: Congrats to GM Mareco! Another report from the 10th American Continental Chess Championship 2015:

Sandro Mareco is at the moment (as of mid-2015) the highest rated chess player of his country, as mentioned above with an ELO of plus / minus 2600, meaning actually that Argentina has no Top Hundred player in the year, legendary Oscar Panno, the first Argentine born GM, is celebrating his 80th birthday *those were the days*
