The paper under review gives aa conjectural combinatorial rule for the structure constants of the cohomology ring (in the Schubert basis) of the maximal isotropic Grassmannian of the odd orthogonal groups in terms of `isotropic: checker games'. This (conjectural) combinatorial rule is arrived at by a sequence of linear and quadratic degenerations following the corresponding work by R. Vakil for the standard Grassmannians (for \(\text{SL}(n)\)).
