Double whammy

 I cannot get around it. We must talk about the double whammy move. After a tactical streak of 150 days training in a row, some characteristics started to jump out on me. One such  characteristic is the omnipresence of the double whammy move. We have talked a lot about duplo attacks in the past. Like the pin, the skewer, the double attack and the discovered attack. All these attacks can be reckoned as double whammy moves. They strike at two targets at the same time. But looking at tactical problem after problem, I noticed that there was very often a tempo battle going on. As FM Charley Story uses to say, a tempo can win a game. Just one tempo is sometimes enough. And there are a whole lot of moves that cannot be characterized as a tactical theme. These moves do not only what they do, but besides that they maintain the pressure. I talked about them in the past as moves with an additional punch.

I decided to throw the moves with additional punch and the duplo attacks on one pile: the double whammy moves. If you recognize the double whammy moves in a tactical problem, you are half way the solution.
