I guess that after 17...b5 18.cxb5 the position is equal(I thought that black is
better but I changed my opinion)
Here is shredder7's opinion

Fritz8 likes 20.bxa6 after 19....Qxc3
I tried the aternative 20.Qxc3 Rxc3 and analyzed with Fritz8
Fritz8 failed high on 21.bxa6 so I analyzed with shredder7 and shredder7 failed
low on 21....Ba8 and still did not solve the fail low at the time of this post.
