Looking for help on tactics

[Kempelen]

Hello,

I want to train my tactical ability to spot opponent chances in a possition. Doing lot of tactical problems of type "I move and win" has made the habit in me to look only for my chances, and sometimes even If I am strong at solving them, I can blunder becuase of that habit.
To fix the bad habit, I was thinking on doing exercises of type "avoid move", "prophylapxis", or similar. But I have asked in chess forums for that type of exercises, books, ...., but none exist; so I was thinking in computer chess, I mean:

1) are there epd suites like what I have described? and been reasonables for human (not long combinations only able for cumputers?

2) If no, any ideas how I can build them using a modified engine to write positions and solutions on a file after examining a collection of lot of games??

Thanks.

Given a position let an engine analyze it at multipv 4, can be 5 or more. If the scores of the first 3 pv are close and the score of the 4th pv is far say -50 cp from the score of 3rd pv then the move in the 4th pv can be considered as a move that should be avoided. Thru experiments you may decide the score of the first pv, whether it is winning or equal, or the difference between the score of first pv and 3rd pv, material balance and others.

One way of doing this thru a script, reading the pgn file and analyze positions there with an engine. Have a look on Python-chess library, it is capable of doing this.
