1. g1f3  1... d7d5  2. d2d4  2... g8f6  3. c2c4  3... d5c4  4. b1c3 In a must-win situation, Krasenkow  is ready to sacrifice a pawn. And not only one... 4... a7a6  5. e2e4  5... b7b5  6. e4e5  6... f6d5  7. a2a4 Just like Dubov yesterday, White tries to force concessions  on the queenside before launching his kingside attack. 7... e7e6  8. a4b5  8... f8b4 is the old line (8...Nb6). 9. d1c2  9... d5b6 The first major thought by Praggnanandhaa. 10. c2e4  10... d8d5 Some  more minutes were spent here. Apparently the young GM was wondering why  Krasenkow was entering this line. 11. e4g4  11... a6b5  12. a1a8  12... d5a8  13. g4g7  13... b4c3  14. b2c3  14... a8a1 This counterplay is what the line is all about.
