Flop 8♦ 7♣ 2♥ - you flop top two pair. You check, and the button c-bets.

You flopped two pair out of position and he c-bets 800. Best?

WhyCheck-raise for value. Out of position with a strong but vulnerable hand, raise to build the pot now and charge the many draws and overcards that float a c-bet. Just calling lets dangerous turn cards come cheaply.
What happensYou check-raise to 2,400; he calls. The money goes in on the turn and your two pair holds.  You win.
Out of position with top two pair, you check-raised for value and protection rather than slow-playing - building the pot while charging the draws. Strong-but-vulnerable hands want action now.

Check-raise strong, vulnerable made hands for value out of position - build the pot and deny cheap cards instead of trapping.
