"This bid is now in a formal process so we have to play by the rules. Of which Jeff is a master at."
First, the last 'sentence' ends in a preposition, and really is a description of the word rules, so would be better with a comma. The 'of which' makes this into a clause, not a full on sentence, and it needs to be tied to a sentence.
"This bid is now in a formal process so we have to play by the rules, of which Jeff is a master."
I hope this was an internal memo, which could account for a slightly less formal style.
