The Threat is Stronger Than the Execution

"The threat is stronger than the execution"-Aron Nimzowitsch

I just played a 3 game tournament, one time Nimzo's sage words helped me gain a victory and in my only loss it was due to not heading his advice. Below is both of those games (in puzzle form) and also an interesting tactic from my 3rd game. Remember, more times than not the threat is better than the execution.
