烏鷺

在FB的圍棋群組見到一個帖介紹一本（英文）新書，封面是一隻烏鴉一隻白鷺，有群組成員問兩動物有甚麼意義？有人答兩種鳥分別代表黑白棋，亦有人質疑指動物背後有更深刻的意思，我不知後者對不對，且看這個台灣網頁怎麼說？

最早提及烏鷺的詩文是唐朝詩人解縉的大作：“雞鴨烏鷺玉楸枰，群臣黑白競輸贏。爛柯歲月刀兵見，方圓世界淚皆凝。河洛千條待整治，吳圖萬里需修容。何必手談國家事，忘憂坐隱到天明。”直到了宋元年間才開始出現大量以烏鷺代指圍棋的詩文

2017 Indycar championship

It was a busy weekend for auto-racing fans! All 3 of the NASCAR series, F1 as well as IndyCar raced during the weekend. To be honest, IndyCar normally doesn't get the highest priority but it's different this weekend because IndyCar will crown its champion at this final race of the season with 6 drivers still mathematically eligible! Based on the history of the past few seasons, Penske drivers came to the race leading in points were totally capable of screwing up their chances. I still remember how Will Power squandered his lead years after years until he finally won one. And just 2 years ago, Juan Pablo Montoya was leading the championship entering the last race but crashed with Will Power and losing the championship to Scott Dixon from Chip Ganasse Racing. In fact, I think Dixon has a good chances to do it again this year even though he was behind Josef Newgarden of Penske racing in the standings. The point gap would have been bigger if Newgarden didn't crash chasing teammate Will Power exiting the pit during the penultimate race. (I seriously questioned why the team decided to pit both drivers on the same lap!) Team Penske drivers were again fighting for the lead during this race. The defending champ Simon Pagenaud got ahead of polesitter Newgarden with a different pit strategy. Luckily no crash this time and Newgarden finished second safely and become the first American IndyCar champion in 5 years (the last one was Ryan Hunter-Reay) Glad to see that. (Newgarden's sponsor Verizon, which was also the series title sponsor, should be happy too. Their CEO Lowell McAdam flew all the way to California to present the trophy to their own driver!) These two and fellow American Alexander Rossi (2016 Indy 500 Winner who also won at Watkins-Glen last month) should increase the interest in the sports among Americans in the coming years. (Forbes agreed too)
