<human>: Can you provide a brief rundown of the text in within 3 sentences?

Just to clarify, a position may be opening up in a different location from our current one.  He wants to do a lateral move, as it would be the same position for him (manager), but it would be a promotion for me (currently assistant manager).  We have currently worked together for over 4 years, and at the time when he got the manager position, I had applied for it, as well.  They chose him because we had prior work history and make a great team; also, he had *1 month* more experience as an assistant back then.

So, what I am wondering is... Have any of you gone through this?  What was your strategy, and did it work?  Also, if you are an employer, what would influence you to consider the "less experienced" applicant?  We are very similar, in many regards, and I'm having a hard time imagining how I can talk myself up without looking like I am disrespecting my boss (who is awesome).  I really want this job, so please help me, Reddit!
<bot>: I want a job, and so does my boss.  What did you do, would you do, or do you think I should do in order to look like the better candidate (without trashing my boss)??
