AB - We list some open problems concerning the polarized partition relation. We solve a couple of them, by showing that for every limit non-inaccessible ordinal α there exists a forcing notion ℙ such that the strong polarized relation $\binom{ℵ_{α+1}}{ℵ_{α}} → \binom{ℵ_{α+1}}{ℵ_{α}}^{1,1}_{2}$ holds in $V^{ℙ}$.
