Longest Decisive Game Without A Capture (continued)

WHAT grandmaster Larry Evans apparently did not know when writing his column for the October 2001 edition of Chess Life was that the record set in 1993 for the longest decisive game without a capture had been beaten by a couple of unrateds not long after it was set.

A typical-looking Hippo

White has completed his development, including bringing his rooks to the centre files, without allowing himself to be provoked into overreaching.
Black presumably hopes White will present a target. Meanwhile he quietly manoeuvres with his pieces on the back two ranks. He has no obvious weaknesses, but is passive and lacks space.
14.Qd2 Ng8 15.h3 e5 16.Bc2 h6 17.Be3 Rd8 18.Nh2 Kh7 19.f4
White is at last ready to take some action on the kingside. This is often the critical point in Hippo games.
19...f6
My main analysis engines strongly dislike the text, but reckon White is better anyway after 19...c5  (Stockfish10) or 19...Ngf6 (Komodo9). They also reckon 19...Qe7 keeps White's advantage within manageable bounds.
20.Qf2 Ne7 21.Rd2 Rh8 22.f5
This has been in the air since White's 19th move. It is clear Black's king is less safe.
22...g5 23.Bd1 Rb8!? 24.Bh5 Qf8
More consistent with Black's last move was 24...Qd8 or 24...Qc8.
25.Ng4
An immediate 25.Bg6+ was possible, taking advantage of Black's undefended knight at d7, eg 25...Nxg6 26.fxg6+ Kg8 (26...Kxg6 27.Qf5+ etc) 27.Qe2 with a very strong attack.
25...Ba6 26.Red1 b5 27.b4 a4 28.a3 Bb7 29.Rd3 Nc6?
This allows mate. Black was positionally lost anyway, but should have made White prove it.
30.Bg6+ Kg8 31.Qa2+ 1-0
This beats the Gual Pascual - Bates game by one half-move. But Bates still holds the record for the longest decisive game won by Black without a capture...unless someone knows otherwise.
