>if CM6K played 62..d3 and fritz played 63 Kf8 its a draw,but fritz can win the game with 63 Ne4.Black can play 63..Bd5 attacking the night.white play's 64Nd2
64..Kg8  65 Kd6  65..Kf7  66 Kc5 the only way to save the pawn is 66..Bb7 67 Kc4
67..Ba6+  68 Kc3 how will the king protect the e and the h pawns.if 68..Ke7
69 Ne4 and the king can't get back to protect the h pawn.the Bishop has two
sguares a6 and b5 to protect the pawn.69..Bb5 70 Ne4 the only move is 70..Kg8 to
protect the h pawn.71 Nd6 attacking the Bishop  71..Ba6  72 Ne8 headed for c7
if the king tries f8 or f7 then Nf6 wins the h pawn.72..Bb5 what else does black
have, 73 Nc7 attacking b5 and e6.73..Bd7 74 Kxd3 74..Kf7 75 Kd4 75..Ke7 76 Kc5
76..Bc8 77 Nb5 77..Ba6  78 Nd6  78..Bd3 79.Kc6 79..Bc2  if ( 79..Ba6 80 Ne4 and
the h pawn falls.) 80 Kc7(how can black protect the e6 pawn??.HE can't haha)
80..Bb3  what else 81 Nc8+ 81..Kf7 82 Kd6( the end is near)I can analyze alittle
farther,but the win is easy.the only thing 62..d3 does is prolong blacks agony.
