Some sacrifices are also instinctive or simply based on judging the position and the results can be seen much later, after a few moves.
However there are also sacrifices which are made more in desperation than in calculation.
The general tendency of amateurs or sometimes even Master’s is to try and bluff in a position which is not going your way.
In the game which follows, the players fight more or less on equal terms, till the 21st move when Black suddenly decides to sacrifice his rook for the knight, more in speculation than calculation.
The resulting loss is immediate as this sacrifice backfires and Black achieves nothing from it.

Black decides to sacrifice the exchange which is difficult to understand.
The position was not to his liking and he tries to bluff his way out, hoping for some respite but he now remains simply material down.
If 21...Bxc5 22.dxc5 Rxc5 23.Qa3 Rc7 (23...b6 24.Nd3 Rc7 25.Rxc7 Qxc7 26.Rc1) 24.Qxa7 Rxc2 25.Nxc2 also result in a better position for White

Things are totally in White’s favour now
30...Qe5 31.Qg4+ Kh8
32.Nd3 Qb5 33.b3
Playing solidly
33. ..Rg8 34.Qh3 Qd5 35.Rc2 Rg6 36.Nf2
If 36.Rc8+ Rg8 (36...Kg7 37.Rc7+ Kf8 38.Qxh7)
37.Rxg8+ Kxg8 38.Qg4+ Kh8 39.Nxf4 also win for White
36...Rh6 37.Qg4 Ng3+ 38.Kg1 f5 39.Qg5
More accurate is 39.Rc8+
39...Rg6 40.Qh4 d3 41.Rxd3 Ne2+ and Black resigned as the King simply moves to 42.Kf1 or 42.Kh1and there is nothing he can do to hang on.
