Here is the old CAP record:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - acd 14; acn
1313815153; bm Rxe6; ce 84; id "BS2830.05"; pm Qh3; pv Qh3 Rh8 Nd2 Na5 Ne4 Qd7
Ba4 Nc6 Qf3 Rhe8 Ng5+ Kg8 Nxe6 Bxa3 Bb3 Rxe6 Bxd5; c0 "Sturua-Kutirow, 4/97-39
Rochochade Europa, 1976";

And the new one constructed from your data:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - acd 18; acn
163024280135; bm Rxe6; ce 149; id "BS2830.05"; pm Qh3 Rh8 Re2 Qd7 Rde1 Nd8 Ne5+
fxe5 Qf3+ Ke8 Rxe5 Nc7 d5 b5 dxe6 Qc6 Qe3 a5 Qd4 a4; c0 "Sturua-Kutirow, 4/97-39
Rochochade Europa, 1976";

The burning question is, who is right?  The GM or the computer.
