i think a call is correct here, he has JJ+ 22+ AND AK,AQ,AJ.He could have 22 or 99 but i think most of the time he is doing this with AA KK AKd AQ, KQ and maybe JJ depending on your image.I def. dont think he is taking a chance of raising you out the pot with a set of 2's or 9's. so yea a call is correct.
