$100nl how should kk be played here?

[allaboutheu]

Should I try and get it all in preflop here? After the one player goes allin and theres a caller should i flat call, raise, or go allin? It seems to me that a raise would just build the pot as if I raise any significant amount I would have put close to half my chips in. Any advice on how I should have played this preflop?

I would reraise instead of calling CO raise.
