FSR: <Phony Benoni> Fortunately I managed to make out Kupchik's notes. Here they are:Note to 3...Nf6: (a) Superior to N-Q2.
Note to 4...cxd4: (b) The right continuation after B-B4 is NxP 5.PxP P-QB3. [FSR - as in Giovanis-Rhine, Chicago 1974.]
Note to 6.Bb5: (c) A wasted move. 6.Q-Q3 or Q-K3 seems much better.
Note to 13.Qd4: (d) A lost move. Q-N4 ought to have been played here.
Note to 15.Rad1: (e) Sacrificing a pawn in order to get out of difficulties.
Note to 17.Qxc3: (f) If PxB instead, 17...B-N2 would win the pawn anyway.
Note to 25.Re3: (g) K-N2 came into consideration here.
Note to 26.Kg2: (h) On account of 26...R-R1, QxRP would have been out of place.
Note to 34.Rxd4: (i) Giving up a rook for knight and three pawns.
Note to 36.Qxd6+: (j) BxP would have been better, for then would follow: 36.BxPch K-N1, followed by B-N4, thus preventing the decisive move R-K8 with good drawing chances.
Note to 37...Re1: (k) Threatening a mate in three moves.
Note to 38.Bd6: (l) Overlooking a mate in three moves, but the game was hopeless anyhow. If 38.B-Q4+ [FSR - I think this is a typo, and that 38.Q-B4+ was intended.] QxQ 39.PxQ R-QB8, winning two pawns.
