Question: In general, is noting a check/checkmate sufficient to disambiguate moves in descriptive notation?
If for example two of the same type of piece could move to the same square, but one giving check and one not giving check while doing so, is it necessary to further distinguish between the moves when recording in descriptive notation?
Take for instance the following position:
r2k3r/pbp1bppp/1p3n2/2p3B1/3N4/2N5/PPP2PPP/2KR3R w - - 0 1
In algebraic notation, according to the FIDE Laws of Chess (Appendix C), we would write 1.Ndb5+ (or just 1.Ndb5) and 1.Ncb5. The '+' to mark checks is optional.
However in descriptive notation, what do we need to write? Is writing 1.N-N5ch for 1.Ndb5+ and 1.N-N5 for 1.Ncb5 sufficiently clear, or do we need to specify 1.N(Q)-N5ch and 1.N(B)-N5?
Further test cases to justify responses with:
1.Bb5+ and 1.Bg5: 1.B-N5ch and 1.B-N5, or 1.B-QN5ch and 1.B-KN5?
rnbqkb1r/pp3ppp/3ppn2/8/3NP3/2N5/PPP2PPP/R1BQKB1R w KQkq - 0 1
1.Qa8+ and 1.Qh8#: 1.Q-R8ch and 1.Q-R8 mate, or 1.Q-QR8ch and 1.Q-KR8 mate?
5k2/8/4K3/8/8/8/8/7Q w - - 0 1
1.Bxf7+ and 1.Bxc5: 1.BxPch and 1.BxP, or 1.BxKBPch and 1.BxQBP?
r1bq1rk1/p1bn1pp1/3p1n1p/1pp3N1/4P3/1BNPBR2/PPP1Q1PP/R5K1 w - - 0 1
