just open nexus first and pull 12 probes to attack lings and with reasonable micro u can just hold it off and be ahead, or if you scout the zerg doing 6 pool take ur probe to bottom of their ramp and make 3 pylons by cutting probe, or do the forge cannon trick, but u should make a cannon in the natural as well cus if lings atk it, then they atk ur main later and u just cancel nat cannon, if not u save ur natural as well as main.
