6 move 8B+ by Gräbner

After 3 years and at least 100 tries, Ingo Gräbner has made the first ascent of Sea of green at Tretboot. The problem is short, only 6 moves, something that is pretty rare when it comes to high end problems. According to Ingo, the 5th move is a one-percenter.Last 30 days he has done four 8A+ but no 8B yet. All things taken into account, 8B+ sounds nothing but brave and logic;) Congrats ol´ chap!
