xxxx2 out there is no problem to 33 nor to 22. xxxx3 out there is a problem to 22 but not to the 33. So, it would count that one extra safe card that the 33 has, and that's not nothing as there are only somewhat over 10 different cards on the deck (five on the board).

Some minor thing there is in favor of the 22 (vs. the 33); when the 2 boards the 22 has a strong hand (and the 33 will not fold as easily) but when the 3 (or any higher card) boards (as the bottom card) the 22 is looking weaker.

There seems to be some reversed similarity when comparing big pairs, e.g. AA is a bigger favorite over the KK than KK is a over the QQ. From that point of view, as the AA is so good, one could think that maybe the 22 is comparatively bad.

Just for the wonder of it, at Stars I have after about a 10K of hands at my new limit a very much higher win rate with the KK and QQ at limit holdem than I have with the AA - that rates at the level of the JJ.
