Effect Spells: Most effect spells summon or create something and are not subject to spell resistance. Sometimes, however, spell resistance applies to effect spells, usually to those that act upon a creature more or less directly, such as web.
Spell resistance can protect a creature from a spell that’s already been cast. Check spell resistance when the creature is first affected by the spell.
Check spell resistance only once for any particular casting of a spell or use of a spell-like ability. If spell resistance fails the first time, it fails each time the creature encounters that same casting of the spell. Likewise, if the spell resistance succeeds the first time, it always succeeds. If the creature has voluntarily lowered its spell resistance and is then subjected to a spell, the creature still has a single chance to resist that spell later, when its spell resistance is up.
Spell resistance has no effect unless the energy created or released by the spell actually goes to work on the resistant creature’s mind or body. If the spell acts on anything else and the creature is affected as a consequence, no roll is required. Creatures can be harmed by a spell without being directly affected.
Spell resistance does not apply if an effect fools the creature’s senses or reveals something about the creature.
Magic actually has to be working for spell resistance to apply. Spells that have instantaneous durations but lasting results aren’t subject to spell resistance unless the resistant creature is exposed to the spell the instant it is cast.
When in doubt about whether a spell’s effect is direct or indirect, consider the spell’s school:
Abjuration: The target creature must be harmed, changed, or restricted in some manner for spell resistance to apply. Perception changes aren’t subject to spell resistance.
Abjurations that block or negate attacks are not subject to an attacker’s spell resistance—it is the protected creature that is affected by the spell (becoming immune or resistant to the attack).
Conjuration: These spells are usually not subject to spell resistance unless the spell conjures some form of energy. Spells that summon creatures or produce effects that function like creatures are not subject to spell resistance.
Divination: These spells do not affect creatures directly and are not subject to spell resistance, even though what they reveal about a creature might be very damaging.
Enchantment: Since enchantment spells affect creatures’ minds, they are typically subject to spell resistance.
Evocation: If an evocation spell deals damage to the creature, it has a direct effect. If the spell damages something else, it has an indirect effect.
Illusion: These spells are almost never subject to spell resistance. Illusions that entail a direct attack are exceptions.
Necromancy: Most of these spells alter the target creature’s life force and are subject to spell resistance. Unusual necromancy spells that don’t affect other creatures directly are not subject to spell resistance.
Transmutation: These spells are subject to spell resistance if they transform the target creature. Transmutation spells are not subject to spell resistance if they are targeted on a point in space instead of on a creature. Some transmutations make objects harmful (or more harmful), such as magic stone. Even these spells are not generally subject to spell resistance because they affect the objects, not the creatures against which the objects are used. Spell resistance works against magic stone only if the creature with spell resistance is holding the stones when the cleric casts magic stone on them.
They're all Evocation effects that work directly on a creature's body...
I would guess you can 'push past' the Interposing Hand without being slowed to half-speed, automatically win Bull Rush and Grapple checks against the Forceful Hand and Grasping Hand, and take no damage from the Clenched Fist.
