Latest Stockfish development build is a tactical monster

I wonder of this affects the playing strength. It might even lower it.

Decided to give it f6 and again stockfish needs a big depth to see that Bxh3 is losing and I guess the main problem is to find c7 because stockfish expects Rh1 at depth smaller than 51.

Decided to give it f6 Bxh3 c7 and stockfish believes c3 is saving black until it see Rd8
