Non-Forced Sacrifice, Example
- Overview -

Chess Sacrifices, Chess Tactics, Non-Forced Sacrifice example. The Non-Forced Sacrifice: White's Ng5 (yellow square).

White has just ignored the advance of Black's h-Pawn (red square) and, instead, chose to advance his own
h-Pawn (h2-h4)

The Reason: By deliberately choosing to sacrifice the Ng5 (to ...h6xg5), White's own h-Pawn can recapture (h4xg5) and leave White's Rh1 Controlling the Open
h-File, all the way up to Black's back rank right next to Black's Castled King.

PGN File(s) [+]Show
In this example of a Non-Forced Sacrifice, you see that White invites the Sacrifice of his Knight ...

However, there's no immediate threat to any of Black's major pieces, or to immediately to his King, which means there's no need to accept White's sacrificial plan.

In other words, Black is not Forced into capturing White's sacrificial piece.

What you'll see are two example outcomes - first, if Black Accepts; and second, if Black Declines the bait ...

Sacrifice Accepted by Black:

Move 1, White's kNight treks up to g5; Black's h-file Pawn advances to h6.

Move 2, White, by advancing his h-file Pawn, to h4, puts his Knight up as the Sacrificial bait ...

Black is in a position where he's not Forced to capture the Knight, but, in this example, does so, with his h-file Pawn capturing (x) it, on g5.

What follows is White's Reason for the attempted Sacrifice ...

Move 3, White's h-file Pawn captures (x) Black's Pawn, on g5 ...

Now, because of the threat of "Checkmate", by White's Queen - backed up by her h1 Rook - Black must block the White Queen's path, by advancing his g-file Pawn, to g6.

Move 4, White's g-file Pawn is then free to realize the benefit of the earlier Sacrifice, and captures (x) Black's Knight, on f6.

Incidentally, because White lost his Knight, but was then able to make up the deficit, by capturing Black's f6 Knight, this is what's sometimes known as a "Pseudo Sacrifice".

It doesn't have to be a like-for-like piece, as long as it gains or evens-out the loss of material, nothing's really lost, in terms of material disadvantage - hence the reference to it being a Pseudo Sacrifice.

Sacrifice Declined by Black:

Move 2, White's h-file Pawn advances to h4 ...

And, because there's nothing hugely threatening to his side, Black, instead of accepting, decides to refuse the Sacrificial offering and freezes-out White's Pawn, by advancing his own h-file Pawn, to h5.

Clearly not a move that would have gone down well with players from the Romantic era of Chess.

Moving On: Example of a Sacrifice to Gain Position (Page 4).
