In the post mortem Flohr contended that White should have exchanged on d7, but the other masters thought it would have been wrong to exchange the Knight for the bad Bishop}) 11... Qxd7 {In view of the weak pawn skeleton c6-d5-e6-f5, it would seem important for Black to preserve his light squared Bishop for the defence, and according to Flohr, it's absence from d7 will weigh decisively in White's favour as soon as he succeeds in opening some lines} 12. Nd2 g5 13. Nf3 Qg7 14. Qc1 g4 $2 {Flohr supposed this to be forced, but it tips the balance in White's favour. White's Knight now gets a support-point of the utmost importance on f4, from which it can blunt the coming Kingside attack.} (14... Ne4) 15. Ne5 Nb8 16. Ba3 {Exchanging Black's good bishop} 16...
