I got carried away
with the idea of sacing a N on h7 as it was possible to chase the Rf8 away.
while all the other pieces could be used for a quick direct attack on the
Black K. Missed a key line which Fritz spots that Re4 is a blunder
12.Neg5 J Grant suggested that a better line is 12. Nfg5
12...h6 13.Nh7 [13.Nh3!?= should be investigated more closely]
13...Rfe8³ 14.Ne5 f5 15.Qh5 Nxe5 16.dxe5 Kxh7 17.Re4?? [¹17.c4 and White has air to breath 17...Qc6 18.cxd5 Qxd5 19.Qh3³]
17...Bf8 [¹17...fxe4 secures the point 18.Bxe4+ Kg8 19.Bxh6 Nf4-+
(19...gxh6?? 20.Qg6+ Kf8 21.Qxh6+ Kg8 22.Qh7+ Kf8 23.Bg6 Qxe5 24.Qf7#) ]
18.Bxh6 18...gxh6?? a transit from better to worse
[¹18...g6 with excellent chances for Black 19.Qh3 fxe4 20.Bxf8+ Kg8-+]
19.Rg4= The mate threat is Qg6 This is the position I'd been aiming for
19...Ne7 20.Qf7+ Kh8 Black threatens Qxe5
21.Re1 21...Qc6?? [¹21...Qc5= and Black can hope to survive]
22.Re3+- Qd5 [¹22...Qxg2+ 23.Rxg2 Bxg2 24.Kxg2 Bg7+-]
23.Reg3 The mate threat is Rg8
23...Qxg2+ Black has to return some of his gains
24.Rxg2 The mate threat is Qf6
24...Bxg2 25.Rxg2 Rec8 White now must not overlook the idea b5
26.Bb5 [26.Qf6+ Kh7 27.Be2 Rc4 28.Bxc4 Rc8 29.Be2 a6 30.Bh5 b5 31.Bg6+ Kg8 32.Qf7+ Kh8 33.Qh7#]
