Polgar - Spassky 1993 : 16. Bg5!

[Vinvin]

I repost the 3rd position from here : http://www.talkchess.com/forum/viewtopic.php?t=60953

It's strange it's so hard for SF to find a clear advantage for Bg5! here :

[d]r2qrbk1/1bpn1p1p/p4np1/1p1pp3/3PP3/1PP2NNP/P1B2PP1/R1BQR1K1 w - - 0 16

After a bit of learning SF select Bg5 with a good score :

Stockfish_170428_x64_modern:
33/64 00:30 315 659k 10 373k +0,55 16.Bg5 h6 17.Bh4 dxe4 18.Bxe4 Bxe4 19.Nxe4 g5 20.dxe5 Nxe4 21.Rxe4 gxh4 22.Rd4 Re7 23.e6 Rxe6 24.Rxd7 Qf6 25.Nd4 Re4 26.Rxc7 b4 27.Qf3 Qxf3 28.gxf3 Rf4 29.Re1 bxc3 30.Re4 Rxe4 31.fxe4 Re8 32.Rxc3 Rxe4 33.Rc4 Rf4 34.Kf1 Be7 35.Nc6 Rxc4 36.bxc4 Kf8 37.Ke2

But at the start, SF only gives 0.00 as several moves for a long time.

Guess that comes cause engines need a while to see ...g5 after ...h6 not to work, neither as 17th nor as 18th
