I propose a new term of abuse - the "checker", a person who checks every move.

Chess is a game of strategy and can be a very interesting theoretical one. 

But there are some individuals, who refuse all theory and refuse to play the game strategically, but would instead rather just check almost every move one after the other and then push for time hoping that they can outperform the other player at.... checking for blunders and tactical shots. 

Even at the world champion level, Alekhine was known to have a "heavy style" (Fischer quote), and was not liked as a world champion. Because he was a "checker" who would go head first into calculations. De la Maza is the epitome of the modern "checking" advocate. 

Checkers are the bane of chess, the guys who come along and ruin everything. And why are they doing it? It makes the game a joke. All the hard work you have to do to make sure there are no tactical shots. It's not satisfying to play them. Going through all those variations is like the manual labour of chess.
