Episode identity and boundaries Determines which grounded striking exchanges qualify and where each episode begins and ends.
Qualifying action pattern
Tests the combination of grounded engagement, positional relationship and striking.
Core case and borderline cases
Use top-position grounded striking as a provisional core case, and preserve uncertainty around bottom-position strikes or brief transitional contact.
- What observed grounded relationship and strike attempt support identifying this exchange as ground-and-pound? definition
- Does the terminology source include bottom-position striking, standing-over strikes or strikes during a scramble? boundary
Temporal segmentation
Separates episodes from the surrounding takedown, grappling and standing phases.
Onset, continuation and end
Record explicit segmentation conventions for first qualifying attempts, pauses, positional changes and termination.
- Which timestamp marks the first qualifying strike attempt, and how precisely can it be located? measurement
- Which pauses or positional changes end this episode rather than merely interrupt its striking? boundary
Ground position and control Records the positional context that makes the striking a grounded engagement.
Participant position
Tracks relative positions and supporting surfaces without assuming that a position name proves control.
Position through time
Represent top, bottom and transitional relationships as time-varying observations, adding named grappling positions only when supported.
- What are each participant's relative position and visible points of support during the recorded strike attempts? measurement
- Which positional labels are supported by the view, and which remain ambiguous? provenance
Control and defensive transitions
Tracks contested control and the opponent's observable responses.
Control is not implied by top position
Keep positional advantage separate from evidence that the opponent's movement is constrained, and record changes such as reversals or disengagement.
- What visible evidence supports describing control as maintained, contested or lost? measurement
- Did a defensive response change the positional relationship, stop the striking or end grounded engagement? boundary
Striking evidence and effect Separates attempted strikes, observable contact and supported effects.
Strike observation
Records what the evidence shows about individual attempts and their contact status.
Attempts, contact and occlusion
Distinguish clearly observed attempts from confirmed contact, defensive interception and indeterminate events.
- How many attempts are visible, and which can be classified as contacting, blocked, missing or indeterminate? measurement
- Which camera angles, replay segments or records support each contact classification? provenance
Episode effectiveness
Assesses effects using explicit criteria and separates observation from causal interpretation.
Effect does not follow from volume
Evaluate visible responses, positional consequences and recorded outcomes separately from strike volume; do not infer injury from activity alone.
- Which criterion defines effectiveness here: observed contact, positional consequence, official scoring assessment or recorded outcome? definition
- What evidence connects an observed change or outcome to this episode, and what alternative explanations remain? provenance
Rules and official intervention Connects grounded striking observations to the governing sporting rules and official decisions.
Rule-conditioned assessment
Evaluates potentially relevant actions using an identified rule text and sufficient event evidence.
Legality requires specific context
Treat grounded status, strike type and contact location as inputs to a rule-dependent assessment rather than assigning blanket legality to ground-and-pound.
- Which ruleset and version governed this event, and how did it define grounded status and prohibited strikes? provenance
- Is the observed action sufficiently clear for assessment, or should the agent flag it for qualified review? action
Intervention and recorded outcome
Records interruptions and outcomes while keeping official explanations distinct from observer interpretations.
Stoppage reason and evidence
Record the timing, type and stated reason for intervention, including uncertainty when the official explanation is unavailable.
- Was the episode interrupted by an official, and what reason appears in the official record? provenance
- Does the evidence justify recording a terminal outcome, a temporary interruption or only an unexplained end to the episode? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

What it is Filled
Ground-and-pound is a combat-sport tactic, especially associated with mixed martial arts, in which a fighter combines top-position control on the ground with strikes against an opponent.
In scope
- Identification and temporal boundaries of ground-and-pound episodes
- Relationship between grounded position, positional control and striking
- Observed strikes, defensive responses and positional transitions
- Episode-level effectiveness, interruption and outcome
- Rule context, officiating and uncertainty in observation
Out of scope
- Complete mixed martial arts bouts and competition formats
- Takedowns considered independently of subsequent grounded striking
- Submission techniques and grappling exchanges without strikes
- Standing striking exchanges
- Medical diagnosis, injury treatment and individual training prescriptions
Why it exists Filled
Enable an AI agent to recognise, describe and assess ground-and-pound episodes in combat-sport records while distinguishing observed actions from inferred intent, effectiveness and rule compliance.
Distinguishing features Filled
- Requires observed striking or attempted striking during grounded engagement; holding a top position alone is insufficient.
- The provisional core case involves a participant striking from top position against a grounded opponent; bottom-position striking must be identified separately where terminology is disputed.
- A preceding takedown can establish context but does not itself constitute ground-and-pound.
- A submission attempt without accompanying strikes belongs to submission grappling, even if performed from the same position.
- A knockout, visible injury or referee stoppage is not required for an episode to qualify.
What robots and AI may and may not do Filled
Must not
- Coach anyone to use the tactic against a person outside a sanctioned contest.
- Describe striking a downed person as acceptable in street fights or assaults.
- Glorify serious injuries or encourage fighters to continue after a referee should stop a bout.
Only with a human decision
- Advising on safety rules for an event or a training programme.
May
- Explain ground-and-pound as a regulated tactic in combat sports and the rules that limit it.
- Describe how referees and medical staff protect fighters.
Moral aspects Filled
- Strikes to a grounded opponent can cause brain injury; rules and referees exist to limit harm.
- Violence outside sport against a downed person is assault.
Who is affected
- Fighters
- Victims of assault
- Young athletes
Owners Filled
Steward
Nobody owns the tactic; athletic commissions and sport bodies set the rules.

- Record defensive transitions and official interventions without inferring medical condition.
- Identify disputed classifications and request additional footage or authoritative terminology.
Hazards and failure modes required Filled
- Strikes can cause concussion, facial injury and other physical trauma.
- Restricted movement beneath an opponent can limit effective defence and increase exposure to injury.
- Incorrect interpretation of grounded status or permitted targets can lead to fouls and inconsistent officiating.
Standards and interfaces required Filled
- The Unified Rules of Mixed Martial Arts, maintained by the Association of Boxing Commissions and Combative Sports, regulate grounded striking where adopted by the responsible commission.
Context of use required Filled
- Ground-and-pound is encountered in mixed martial arts competition, training and analysis of recorded bouts.

Open questions
- Which authoritative terminology sources define ground-and-pound, and do they agree on whether top position is required?
- Should strikes delivered while standing over a grounded opponent and strikes thrown from bottom position fall inside this entry or remain neighbouring action patterns?
- What segmentation convention best handles pauses, brief scrambles and alternating striking and submission attempts?
- Which measures of effectiveness can be applied reliably across footage, statistical providers and different sporting rulesets?
- Does the existing Vercy world-model catalogue already cover this action pattern at the registry's granularity, requiring a link instead of a separate publication?
