Using Heegaard Floer theory we find obstructions for configurations of singular points on general curves in CP^2, generalizing previous results of Bodnár, Borodzik, Celoria, Golla, Hedden and Livingston. We show concrete examples, when "genus cannot be traded for double points". This is a joint work with Beibei Liu and Ian Zemke.
