Two pair plus nut low on the turn? Pump it up!

Boat plus nut low on the river? Pump it up!

It seems unlikely that anybody is voluntarily in the hand with any of the following combinations:

73xx, 7Qxx, and 72xx is made a little less likely since you hold a deuce.

If QQ is in play, you don't stand to lose a lot in a multi-way pot here. Doesn't make sense to me to put on the brakes on the turn or river, but I don't play a lot of limit O8.
