Here is a my first try at putting a puzzle together on here, but it's not really a puzzle...it's more of a demo of a smart trap in the Ruy Lopez. It is white to move and try to end the game quickly - good luck and enjoy.
Here is a simple set of puzzles for you; the experienced players will know these. It is always good to return to basics occasionally. White needs to checkmate here!
