What is the fallacy and definition of the Hypothetical Syllogism

I am trying to learn and EASILY identify fallacy types... Deny the Consequent, Deny the Antecedent (invalid) etc.

Here are a few examples along with my initial response, but it doesn't appear that I got them right (although I don't know what the correct answer would be). Your assistance is greatly appreciated.

I thought this was Denying the Consequent:  

If I master critical thinking then I will be a better employee
I am not a better employee
Therefore, I did not master critical thinking.

I thought this would be Deny the Antecedent:

If I can master critical thinking
then, I will be a better employee
I haven't mastered critical thinking
therefore I am not a better employee.

For the next statement I thought it contained two fallacies: Appeal to Ignorance and Appeal to Authority.

Rhymes' lawyer, Robert Kalina, told the judge, "I can tell you, judge, my client is innocent, and I rarely say this in a courtroom." He added that the accuser had no discernible injuries other than one red mark on his face.
