Black is better

[Dann Corbit]

With a big score. That's pretty amazing

[elcabesa]

can someone explain what's the story of this position and why Bh5 is winning? Stockfish for example like hxg3 or Qe6.

Looks like there is a strong bind against whites position on your above PV from SF10.
I tried to analyze your line further and black could win on a long maneouvre.

[pgn] [Event "?"] [Site "?"] [Date "2019.01.13"] [Round "?"] [White "SF10"] [Black "SF10"] [Result "*"] [SetUp "1"] [FEN "r5k1/1ppq1bp1/2n4r/1BBn1p2/p1NPp2p/P3P1P1/1PQ2P1P/2R3RK b - - 0 1"] [Termination "unterminated"] [PlyCount "11"] [WhiteType "human"] [BlackType "human"] 1. ... Bh5 2. Ne5 Nxe5 3. Bxd7 Bf3+ 4. Rg2 Nxd7 5. gxh4 Rg6 6. Rg1 f4 * [/pgn]

Which will end up with this:
[d]r5k1/1ppn2p1/6r1/2Bn4/p2Ppp1P/P3Pb2/1PQ2PRP/6RK w - - 0 7

then traced the best lines further and could end up like this where black might be able to pull off a win.
[d]5rk1/1pp3p1/8/2P5/p3Qn1P/P5KP/1P2pP2/8 w - - 1 14

Thanks to Dann for this interesting position.

5...Rg6 is weak. Also, "drawish" by Nordlandia is not a good word for his PV position.
