I think this is close between calling and folding, i think this will usually be a big pair so raising probabbly is not a good idea. the question is just whether when you make your hand you will make more than when you miss and when you make it and are beat. against jj or qq you will flop the better hand about 40% i think, kk 15-20% and aa rarley. on average you'll prob be ahead on the flop 25-30% max, so would want 2,3-1 pot/implied odds, which is close to what you are getting, if the 50 is after the raise, if the 50 is before the raise a call is almost like an allin, where you are likley behind, although with that small a stack he may have less than ak
