AQ squeeze and 3b, 50nl regwar sizing?

villains are both winning tag-nits, pretty bad though. One of them huge squeezed my utg on another table a while earlier with QQ and then snapped my 4b AK shove. At least one of them considers me a monkey (he said so in chat), but a monkey with a fold button and the ability to hit the nuts they probably see me as 19-14-6.
both are 24-tabling, and i think they're colluding (both chinese, no big pots together ever, always sit close, etc).

i like this hand a lot, including sizing. Which means that there could be a lot wrong with it.
