Daily Double-B push/fold/call-im confused

[hookem208]

ok, i ended up calling but i dont know if its a clear fold, an easy push or just a toss up. my read on the original raiser was
raised 3x after a raise at 10/20 with AKs, then called all in
raised 2.5x utg+1
raised 3x MP, called all in with QQ

so he hasnt really done anything out of line, but hands ive seen him raise so far have been QQ and AKs, so i could be dominated or coin flipping. my stack is a little low as ive been card dead, so that may be why i pushed. idk. any advice would help, even one word answers like "fold" are great. thanks.
