At this stage even with those blinds, you can't be too far off pushing with every hand. it may not be optimal but basically your chance to win will be close to your chip lead. With that kind of chip diference, there is no counter strategy that the oponent can use that will win more than about 60% on average. For example lets say he has ak 2 hands in a row and you have 47. he is only a 60% favorite here and has to win twice, while you only once, so if you push both hands here you'd win once 65% of the time, and this is with a verry favorable situation for your oponent. More often he is going to have to wait for a better spot but get ground down, or make due being less of a favorite on averge.
