hi all,

Is the famous Botvinnik-line still playable, I don´t get a chance playing it with white (--> due to 5. ...h6), but lots of player allow it, when I play it with black;
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 dc4 6.e4 b5 7.e5 h6 8.Bh4 g5 9.Ng5 hg5 10.Bg5 Nbd7 11.ef6 Bb7 12.g3 c5 13.d5 Qb6 14.Bg2 000 15.00 b4 16.Na4 Qb5 17.a3 ed5 18.ab4 cb4
Now strong players play nearly exclusively 19.Re1 [Wasn`t 19.Qg4 or 19.Be3 the main line?] and I´m not sure about the consequences of 19. ...d4
Any Evaluations and sources?!
