We propose here that the pseudogap phase of high Tc superconductors is probably unconventional spin density wave (USDW). We present our analysis on the angular dependent magnetoresistance (ADMR) in the pseudogap phase which should be accessible experimentally. Also this result applies also to the AF phase of URu 2Si 2. We show that this model is consistent with the optical dichroism seen by ARPES.
