Nakamura failed to covert a piece-up ending against Magnus Carlsen today. (These endings are surprisingly tough: Kramnik failed to convert a similar piece-up ending in his World Championship match with Kasparov.) Doubtless, Hikaru would have had no problem converting this ending had it been played on Saturday, when he will be thirty years old and therefore infinitely wiser.
Celebrate Hikaru's birthday (or, more likely, the weekend) by playing chess!
