There are now so many games broadcast and so many of good quality matches, it's hard to choose. And hard to remember them all! A recent one that was rather dramatic was JJS/LYD vs Fu/Cai in the Hong Kong Open final.
I remember that one! Where LYD had an off day and JJS had to play like a mad man to cover him. I've never seen so many dive saves, but JJS practically had to dive over 15 times in that match.
I would say in terms of the most emotionally charged with the most prestige on the line, the World Championships this year between LD and LCW was probably the most anticipated match of the year. I don't quite recall the level of play but I know that the scoreboard was one of the tightest matches between the two with LCW having match points but LD fighting back to take the match when LCW has lapses in his concentration.
what about XD? what was the best? ZZ vs Fischer/Pedersen? the one in Danmark (which was not broadcast) or the one in HK?
