I wonder if Black would have gone for the perpetual check if White had played
24.Qxc4+ instead of the (probably) losing 24.Be6? E.g.:
24.Qxc4+ Kg7 25.Rf1! Bxg4
[25...Bxf1 26.Rxf1 Rh6 27.Rf2 +=]
26.fxg4
[or 26.Be1 Qh3 27.Qc5 Kh6 28.Bg3 Bxf3 29.Bxf3 Rxf3 30.Rxf3 Rxf3
31.Qxe7 Rxg3+ 32.hxg3 Qxg3+ draw]
26...Rf2 27.Bg2 Rxg2+ 28.Kxg2 Qxg4+ 29.Kh1 Qe4+ 30.Kg1 Qg4+ draw
