ECM.1495
[D]5rk1/p1p1br2/1p1p2qp/4p3/2PPn1pP/3Q2P1/PPN1P1K1/2RR2B1 b - - 0 1
Bm:  Bxh4

Latest Movei prefered Rf3 with almost +3 score for black.

I analyzed the position with yace and yace can also learn Rf3 after I give it
the first moves of the main line of movei(5.Ke3 was not in the main line of
movei and yace found this move in search but 1...Rf7-f3 2.e2xf3 g4xf3+ 3.Qd3xf3
Rf8xf3 4.Kg2xf3 Ne4xg3 is simply forced from white's point of view)

Here is yace's analysis after learning

New position
5rk1/p1p1br2/1p1p2qp/4p3/2PPn1pP/3Q2P1/PPN1P1K1/2RR2B1 b - - 0 1

Analysis by Yace 0.99.56:

1...Rf7-f3 2.e2xf3 g4xf3+ 3.Qd3xf3 Rf8xf3 4.Kg2xf3 Ne4xg3 5.Kf3-e3 Be7xh4
6.Ke3-d2 Bh4-g5+ 7.Bg1-e3 e5xd4 8.Nc2xd4 Qg6-e4 9.Nd4-c2 Bg5xe3+ 10.Nc2xe3
Qe4-d4+ 11.Kd2-c2 Qd4xe3 12.Rd1-g1 Qe3-f2+ 13.Kc2-c3
  -+  (-4.66)   Depth: 1   00:00:00
