When your pawn can capture a piece on the eighth rank, but the promoted pawn will be captured in return, think twice about capturing right away. Consider additional tactical options in order to squeeze the maximum out of the fact that your pawn can promote any time. In particular, take a close look at the guards of the promotion square and see if you can find a way to free the square from its protectors. In the above gif, the key idea is the deflection of the promotion square guardian — the king — combined with the power of the fork. The gif below uses the same idea, employing two deflections in a row.
