Here is what I use when I'm in time trouble
1) DON'T play fast exp if you have five minute left and in the endgame (where most time trouble happens) it is better to play 30sec a move then 15sec a move
2)DON'T trade mindlessly trade if it help you NOT when it dosn't
3)DON'T get in to time trouble in the first place your MUCH more likely to lose the game
I'm going to play in my first OTB tournament this weekend. My ratings in Tactics Trainer and standard chess are lower than my rating in online chess, so I'm concerned about the clock. Are there any general principles or rules of thumb for managing time? For example, if I'm in time trouble, should I look to trade pieces to reduce the amount of calculation?
