Dimitri Reinderman had a rough time of it during his trip to Australia, although he wasn't the first GM visitor to these shores to leave a swag of rating points behind.
But before he made the trek down under he did play the following short game in the Dutch Teams Championship. Although it was played right at the end of March, I'm stretching the rules a little and including it as an April game, for the purposes of this category.
