On that board they have a maximum of 6 outs between them so i dont think you need to rush it. I bet out the flop expecting the K to at least call me or maybe reraise. A checkraise shows too much strength IMO even if you did just min raise it. make it $2-$3 yourself and expect a call. It wont stop you losing your stack here but i think it will get you more value when they just have trips.
