hi all,
what is the latest evaluation of the following line:
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.cd5 Nd5 6.e4 Nc3 7.bc3 c5 8.Be3 [on kramnik`s traces] Qa5 [this is the main move, are there any useful alternatives?] 9.Qd2 Nc6 10. Rc1 cd4 11.cd4 Qd2 12.Kd2 0-0 13.d5 Rd8 14.Ke1
a) 14. ... Nb4!?
b) 14. ...Ne5 was refuted in Kramnik - Leko 2001[?]
c) 14. ...Na5
I`m not sure how to play against line a) and honestly I´m not sure how to handle the white pawns in the center, if white hasn`t something concrete, the black can trust in his bishoppair and his queen majority;
c) 15. Bg5 [Kramnik - Kasparov 2000] Bd7 16. Bd3 now 
16. ...Kf8, why isn´t this obvious move played more often;
black has a clear plan:
to fight for square c4, can shatter the white center with f7-f5, as mentioned he has the bishop pair and the queen majority plus his king has a reasonable function;
who can detect white`s trumps?
