position from Gromit vs Centeur
r4rk1/pb3pp1/1p2p2p/2p1P1PQ/2P1p3/1P2P1P1/Pq1P1RB1/R5K1 w - - 0 1

18.gxh6 is probably winning but I am not sure if it is the only winning move.

Junior5.4 suggests after an hour 1.Raf1 with 1 pawn advantage for white (main
line begins with 1...g6 2.Qh4)
I did not analyze what it wants to play after 1...Qxe5

After 18.gxh6 Qxa1+ 19.Bf1 the move 19...f5 was clearly a mistake.
Junior suggests 19...gxh6 when the evaluation says that white has advantage of
less than a pawn but after 20.Rf6 Qe1 21.Qg4+ Kh7 22.Qh4 Qxg3+ 23.Qxg3
Rg8 24.Rxf7+ Kh8
Junior can see a bigger advantage for white(25.Qg2 with 1.39 pawns after a few
minutes)

It is possible that after Raf1 the evaluation is also going up but I did not
check it.

position from  Arthur vs. Gromit:
 2rr2k1/pb2bppp/1p3n2/n1P1p2q/NP2P3/2BB1N2/P1Q1KPPP/R6R b - - 0 1

Junior5.4 can find Rxd3 in less than a minute on pentium200.
