256 mbytes clear hash

stockfish see advantage for white with Nh4

stopped it at depth 30 after some minutes and 300,000 Knodes

Perhaps, but you need to survive long enough to reach the endgame. :D
Indeed, although my book knowledge is pretty good, those damned thing are monsters at tactics. Even then, I lose most endgames too. 2100 vs 3200 player, the outcome is already expected.

The analysis that I posted is with single processor so people can reproduce it.

I used default parameters(no zugzwang detection) and 256 mbytes hash.

Here's what I get using 1 thread. I have zugzwang detection enabled, and I compiled on my own from source. My other UCI settings can be seen below:
