99 on the button 1-2 hit my set on all diamond board

[jsmith5]

I am dealt 99 on the button with $200 in front of me. There is a min-raise UTG and 3 callers. Sometimes I like to isolate with this hand, but I just sat down at the table. With that many limpers I usually like to play for set-value.

Basically most of the players in this hand have me covered.

Any thoughts on this preflop?

Now, on to the flop (with 6 players for a total of $24):

Checked to short stack of $9.50 in cutoff who bets $4.

Your move?
