Bg5 {This line has become known as the Botvinnik Variation. In this early example, the future World Champion defends the Black side.} 5... dxc4 6. e4 b5 7. e5 { White tries to capitalize on the pin at f6.} 7... h6 8. Bh4 g5 {Now the pi n is broken, but by temporarily sacrificing a piece White can re-establish it.} 9. Nxg5 hxg5 10. Bxg5 Nbd7 11. Qf3 {White could also have captured the knight now. Another plan is 11.g3, followed by the fianchetto of the bishop at g2, with pressure on the long diagonal.} 11... Bb7 12. exf6 Qb6 13. Qe3 O-O-O { 13...c5 14.d5} 14. O-O-O Qa5 15. Kb1 Nb6 16. h4 {Black is attacking on the queenside, and White should not be wasting time advancing the h-pawn. 16.Be2 was correct.} 16... b4 17. Ne4 c5 18. f3 c3 19. Be2 {19.bxc3 Nd5} 19...
