non-conventional: limp. if CO or Button 'make a move' on the blinds....and the blinds fold...i'd let it rip. the blind's shortish stacks are ripe for picking from CO/Button. you're limp (non-push) in front of them may even be more encouraging. short of a hand (...that would probably have you beat), they will be folding to a 4-5x raise. i WOULD take AJo against a raiser in their position. if you did get to the flop for your 50, you'd still have the opportunity to push an A or J high flop.
