Study-like mate in 7
This is computer analysis referred to in a previous blog "Deep Tactics". I thought I would rather present it as a study. If you solve it you are either a genius or a silicon monster! For the record I went wrong with the 'obvious' 24 ... Qf3+ and eventually lost on time.
24/5/2016 Fixed mistake in solution with wrong move order at move 28 and 29 (black).
