White has played a rather artificial system against the Sicilian, and Black has no real problems. White's next changes the natural course of the game dramatically.

Nc6
Black is up two clean Pawns, but his lack of development and potentially weak squares make the position still quite interesting.
17.Be3?!
[17.d4
,taking the center, was natural and good.]
17...e6
[17...Nf6
, developing and pressuring the e-pawn was simpler. ]
18.Rfd1
[Now White could have thrown in 18.Qb2
, forcing 18...Rh7
and White's compensation grows.]
18...Nge7
19.d4
[19.Qb2
again was stronger.]

[This gives back a good chunk of advantage. 23...dxe4
is quite good for Black.]
24.Qa3

[24...Nc6
would have kept things much simpler. Now play gets concrete.]
25.Ba5
Qc8
26.Qd6?!
[Winning the Q for R+B with 26.Rd8+
is clearly best, but the resulting position is not simply converted to a win. White prerfers to keep things sharp.]
26...Nd5
27.g4
hxg4
28.Bxg4
Qd7??
Black had an unhappy task trying to untangle, but this desirable move is tactically refuted. Fritz suggests a slow maneuver involving ...Rh4, ...Rh7, ...Rh8 and ...g5. Who knows if it makes any sense!
29.Rxd5!
Wins a piece and Black must swap Queens to avod being mated. 29...Bxd5, the move Black would like to play, is mated after 30.Qb8+,

Rg1+?
[36...g5!
White must give up the h-pawn now, or submit to a perpetual attack. 37.Rd2
(37.hxg5?
Rg1+
Here is the draw. White cannot avoid the checks and at the same time protect the Bishop.) 37...Rxh4
38.Rd7
White is firmly in the driver's seat, of course, but Black has at least caused some trouble.]

Black was dead lost no matter what, but now White has a mate in 6 beginning with 41.Bf6 Kh7 42.Rd8.
41.Rb6
This should not alter the result, but of course the mating line was quicker.

White has overlooked the mating concept the last few moves, but here it's three moves away: 46.Rb8+, 47.Rxc8+ (assuming Black prolongs the game) and 48.Rh8#.

The scoresheet ends here, with "Black Won" circled! I checked the wallchart and it said the same. I can only assume White lost on time, which can also explain the numerous missed mates. A truly nerve-wracking game to play, I am sure! 0-1
