Dunno about Yace (I'm in front of the wrong machine here) but Fritz 8 continues
with 14.dxc6 into quite a forcing line:

13. ...Bb7 14.dxc6 Bxc6 15.Nb5 Bxb5 16.Bxb5 Nc5 17.b4 Ne6 18.Qxc7 Nxc7

Then the engines start to diverge:

[D] r4rk1/p1n2ppp/1p1b4/1B2p1Pn/1P2P3/4BN2/P4P1P/2KR3R w - - 0 1

I think I was using the most optimistic engine in the initial analysis ;)
