Is there a consistent example of a compact Hausdorff space $X$ on which the following holds?
i) there is a $Y \in {[X]}^{\aleph_1}$ such that $\psi (Y) = \aleph_1$; and
ii) there is no non-trivial converging sequence of type $\omega_1$ in $X$.
Note that the negation of (ii) implies (i) (assuming ZFC of course).
I know only one example of a compact Hausdorff space $X$, with $\psi (X) \geq \aleph_1$, satisfying (ii). It is the one-point compactification $X$ of the (very complex) locally compact space $Y$ constructed in
I. Juhász, P. Koszmider and L. Soukup, A first countable, initially $\omega_{1}$-compact but non-compact space, Topology and its Applications 156 (2009), 1863-1879. doi:10.1016/j.topol.2009.04.004
In this case, I don't know if $X$ satisfies (i).
