The Candidates Tournament is scheduled to take place in Madrid later this year, and there are only two spots still up for grabs, with these two qualifiers set to be decided at the FIDE Grand Prix Series. The first leg of the series kicks off tomorrow in Berlin, only three days after FIDE announced that Ding Liren and Dmitry Andreikin will not make it to the German capital — Radoslaw Wojtaszek and Andrey Esipenko are their replacements.
