Which proton in methyl acetoacetate is most likly to be enolised and what is the most stable enolic form?

 my initial thoughts one of the CH2 protons would be the first because it would form c=c bond in the middle of the molecule and be more stable

Yes, it forms a C=C but you are asked for the enolate structure, can you draw the most stable enolate?

Ok, but you are missing part of the ester and a H atom.
