White to Move and Draw
Okay, you could end up with an endgame whose drawing technique is similar to this one. It's a very practical lesson. So, you've decided to look at the solution:
1. Kb5 h5 2. Kc6 Kc8 to prevent the White king from taking the b7 square. 3. Kd5 and the king is within the queening square of the H pawn. If 2... h5, then 3. Kb7 h3 4. c6 h2 5. c7+ is also a draw.
