We report on the status of ongoing investigations aiming at locating the deconfinement critical point with standard Wilson fermions and Nf=2 flavors towards the continuum limit (standard Columbia plot); locating the tricritical masses at imaginary chemical potential with unimproved staggered fermions at Nf=2 (extended Columbia plot); identifying the order of the chiral phase transition at μ=0 for Nf=2 via extrapolation from non integer Nf (alternative Columbia plot).
