hello im tony n new to chess just taught myself with the help of chess.com n other online venues. Only been playing couple months not that good bounce between 500 n 600  I don't mean to complain but what with all the bad sportsmanship didn't expect it from chess I always resign soon as I know im beat n theres no more to learn from continued play but I usually finish. everyone it seems plays this 90 second abort game n goes bak n forth making take longer to try n make u quit. don't mean to gripe but Its  just weak in my opinion.   sorry to rant have a wonderful day
