Nxf8 Black has can threaten mate with 13... Bb7! forcing 14. Rf2 as the only move to guard the g2-square. Then Black has at least a draw by 14... Qe1+ 15. Rf1 Qe4 etc. That is why NCO recommends 13. Ne5! Bb7 14. Nf3. The knight avoids taking the rook because it has to get to the f3-square to stop the mate. Now Black has no instant draw by repetition of moves and the game continues with its complexities.
