Sacrificing means bidding over the opponents, expecting to fail. You hope that either you will be cheaper than the opposing making (game) contract; or your opponents bid one more and go down.
Players generally over-sacrifice, often committing the crime of taking two bites of the cherry. Sacrificing does not generally pay because if you are left to play (doubled, of course), your bid will only gain if all these factors occur:
- i) You are cheaper than the value of their game
- ii) They were making their game. Plus (at Duplicate Pairs and Teams):
- iii) The other pair(s) holding their cards have bid (and made) game.
Top players hate to make late sacrifices: the opponents have no sensible option other than to double. Advance sacrifices are much better – because now there is a good chance the opponents will bid on (eg 5 ♠ over 5 ♦ ). And now your sacrifice bid can never lose. It will break even if 5 ♠ makes; and gain handsomely when 5 ♠ is one down.

Zero. You have taken the dreaded two bites of the cherry. If you intended bidding to 5 ♦ , you should have bid it first time.
Auction two
Three. Understandable (you hoped 4 might buy the contract), but you’re now regretting that you didn’t raise to 5 immediately, cutting out North’s 4♠ bid.
Auction three
Auction three: Ten. Classic advance sacrifice, hoping North, with as yet undisclosed spade support will go 5♠. Now your 5 ♦ bid can’t lose.
