This strong maneuver again! The rook is eyeing both flanks.
1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. h1g1 It has been a  long time since I've seen this line. Actually, the last time I remember a  top player using it, Magnus Carlsen tried it as White! 6... b7b5  7. g2g4  The point behind White's idea. The sooner the pawn runs, the earlier the  knight has to leave the active f6-square. The question is, who is faster? 7... c8b7  8. g4g5 Or who is braver? 8... f6e4  9. c3e4  9... b7e4  10. a2a4 Nepomniachtchi is blitzing his  moves, including this novelty! 10... e7e5  11. a4b5 Again blitzed out. And after lengthy thought (a bit more than five minutes in a rapid game is a lot!), the world champion decided not to accept the "gift." 11... f8e7
