IM Daniel Fernandez had embarked on a few warm-up events prior to the Istanbul Olympiad in which he tested possible lines to use for the forthcoming event. One of them was the maverick Polish Defence (1.d4 b5!?) in which he felt that Black would be OK if he can get ...c5 in without being punished immediately. Unfortunately (or should it be fortunately?), all his White opponents in Istanbul preferred to test him with 1.e4 so he did not get to 'polish' them.
Here's Daniel's best game from the Baden Baden Open 2012 which he had kindly provided the copious annotations for readers.
