You need a pretty good read on the table/re-raiser to muck KK here. I know Lukie posted a hand a while back where he muked KK to a raise and a reraise preflop, but he had a very good read on the table/villian. If you can elaborate more on reads you might change my opinion from bad fold to good fold, but as it stands now I'd like to at least call and see a flop... with the intention of getting allin on a non Q or A flop.
