Personally being in the big and oop i wud make it 7 or 750 at least this way any rag ace shud get out the way,..ace is the last card you wanna see fall down,it can also look like you are trying to steal in that spot and may have someone come over the top which is what you wud want. Other than that with those two idiots playing the hands they played the way they played shows they full of shit and must be micro stakes. Its not a bad fold by you.
