We study the effects of piece selection principles on cardinal arithmetic (Shelah style). As an application, we discuss questions Abe and Usuba. In particular, show that if λ ≥ 2 κ $\lambda \ge 2^\kappa$ , then (a) I $I_{\kappa \lambda }$ is not (λ, 2)-distributive, (b) + → ( ) ω }^+ \rightarrow (I_{\kappa }^+)^2_\omega$ does hold.
