The workbook 1 extra is a very useful book. In the first half of the book, you will find exercises similar to those we dealt with in the workbook Step 1.

This not only serves as additional practice but also as a review.

In the second half, we will encounter exercises titled "Various". This means that there is no indication of the type of exercise, resulting in the exercises resembling real games more closely. For this reason, the exercises are more difficult than those in the First Step.

However, the topics of the exercises are common: material gain, checkmate in one move, and defense. That's all. For each exercise, the student should seek the correct answer through three questions:

• Can I gain material?
• Can I checkmate?
• Is any of my pieces threatened?
