Some of these puzzles are difficult, so I will give you a hint for each one. The hint will be below the puzzle. So if you don't want the hint, don't scroll down until you have solved it! A big up-front hint is that every move is a forcing check.
White to move in every diagram.
1. Helper mate in 2 or 3.
Hint for #1: The queen and rook work great together on the 7th rank. How can she get there safely?
2. Variation of Morphy's Mate in three.
Hint for #2: A rook sac opens the castle nicely when you have a back-up rook ready to charge!
3. Mate in 4! Remember, each move is check!
Hint for #3: No matter which way the king hides, after your amazing rook sac black is toast.
Superhint! The next 3 puzzles are all discoveries!
4. Mate in two.
Hint for #4: Don't let the king escape from the back rank. What is the most powerful type of check? A double check!
5. Mate in two. Another Morphy's Mate!
Hint for #5: What a lovely open g-file! If you make just any check, that knight on d3 will be annoying and eat your bishop.
6. Mate in 2.
Hint for #6: No one can capture you if you make a discovered double check!
Great work! So you see, the heavy tower is a very useful piece! He's great as back up and as a mater himself. For more practice, some of the links will take you to other puzzles. Click on them!
Tip of the week: What is your favourite piece? Try playing a game with a friend without it. That will make you more versatile!
