Trouble finding good moves? Find bad ones!

1/17/2004 – If you play too many blunders maybe you just need practice looking for them. You have to admit that makes sense in a twisted way and here is your chance. We have an even dozen tactical positions in which you have to find the worst move, not the best. You'll hone your defensive skills and your ability to calculate. Think it's easy to find bad moves? Think again.

A dirty dozen blunders

The following is a selection from a section of a recent issue of Black Belt, a weekly training e-mail newsletter from ChessNinja.com. A previous, and easier, "tactics with a twist" section is here.

We continue to look for ways to make tactics practice more fun, more challenging, and more practical than the old "find the crusher in the diagram." Here you have to find the worst move from the options given. Simple, but not easy.

Get some paper or open a text document or tell your secretary to take dictation for this one. Go through each position and choose the blunder from the options listed. This means finding the worst move in the position. Sometimes the other moves aren't that great either, but this is about recognizing threats and learning to play defense.

If you can find the blunder that means you can avoid the blunder. Don't just note down a, b, or c. Give the lines in all the variations if you have the time. Several of these are very difficult so don't just find what you think is a killer refutation of one of the moves and then jump to the next one. Examine all the options carefully. Of course you will also examine the position itself carefully first, right? Being aware of the general tactical potential in a position is key to both finding and avoiding killing tactical shots.

If you notice several themes reoccurring it's no coincidence. All of these positions are selected from recent (2002-2003) Master games that started with the Sicilian Defense! They aren't all thematic, but the entire games are below and on the replay/download page so you can see the evolution.

Interesting puzzles. I think there are two types of puzzles on this page.
Puzzles #2 versus #3 are different types.

In #2 the color on turn, in this case Black, might survive even if he could magically skip his turn by playing the null move. The student is looking for the Black move that *creates* a huge problem where none currently exists.
I had expected most of the puzzles to be like #2.

But in #3 the null move fails because it neglects to negate a huge problem that *already* exists. The page of puzzles seems to contain several that are like this.

Both puzzle types have value, but personally I prefer the puzzle type that #2 represents.
