When you're getting 2:1 odds, you need an excuse to fold, not an excuse to call. Except in extreme bubble situations, you should essentially never fold a PP HU getting 2:1 because there's no reasonable range you can put your opponent on that justifies this:

equity (%) win (%) tie (%)
Hand 1: 37.4300 % 37.14% 00.29% { 2c2d }
Hand 2: 62.5700 % 62.28% 00.29% { KK+, AKs, AKo }
