Which currently active chess player tends to play complicated positions? In earlier years, Michail Tal would be a candidate for this topic. 

Which player could be a candidate today for regularly playing complicated positions ?
Alexander Morozevich probably obtains the most consistently complicated positions of any >2700 player, although he has fallen off some since the mid-2000s.

Baadur Jobava is probably his rightful successor, but a recent string of horrible tournaments pushed him under 2700 and he is now sitting at 2699.
