13vT, 13vA, 14v9, 14vT, 14vA, 15v2, 15v8, 15v9, 15vT, 15vA, 16v2, 16v7, 16v8, 16v9, 16vT, 16vA, 17v8, 17v9, 17vT, 17vA (obviously, as it is a surrender for basic strategy also).
Notice how only one hand in Spanish 21 has worse than a -0.5 EV (17vA), but exactly 20 hands, the worst starting 20 hands in the game, are worse than -0.333 EV.
