8. Scoring and Points in Full-Contact Kickboxing, Thai-Boxing and
Original GCO kickboxing rules (K-1)

Decisions shall be made after the following guidelines:
Victory on points (P)
When neither competitor dominates the other and a round is even: 10:10 points. Following this points are added to or subtracted from each competitor’s score according to the number of points they have been noted for by the referee.
The winning competitor of a round receives 10 points, while his/her opponent receives 9 points.
If an official warning was given because of a “foul”, the judges shall immediately award this competitor with “first warning”. The judges shall always mark these warnings with the letter W (for warning) under “fouls” on the scorecard to indicate that the competitor has received a warning.
If a competitor has receeived a “second warning” because of a foul no point is to be deducted but the judges shall immediately award this competitor with “second warning”.
If an official minus point was given because of a “foul” by clear and brutal strike and this is not merely a warning, or this warning is issued simultaneously with the third warning, each judge must deduct 1 point from the scorecard of the involved competitor immediately when the round is over. (i.e. 10:9) The judges shall always mark these points with the letter M (for minus point) under “fouls” on the scorecard to indicate that the competitor has received a minus point.
If a second official minus point was given, than the fighter is immediately disqualified.
If a competitor is knocked down, each judge must deduct 1 point from the scorecard immediately when the round is over (i.e. 10:9). The judges shall always mark this knockdown with the letter K (for knockdown) under “KD” on the scorecard to indicate that the competitor has received a knockdown.
A score with fewer than 8 points can only happen if the judge gives a 10:8 score for the round and points were deducted as well.
At the conclusion of the match all rounds are added up to the final score (i.e. 30:27) and the competitor with more points on the scorecards shall be declared the winner.
Should a judge observe a violation that has apparently escaped the notice of the referee, and if he/she subsequently imposes a reasonable sanction upon the competitor committing the violation, he/she shall indicate that he/she has done so by marking the points of the violating competitor with the letter J (for judge’s minus) and in writing state his/her reasons for the sanction.

Victory by attending physician stopping contest or injury (DOD)
The attending physician is the supreme authority in questions relating to the safety of the competitors, and may demand that the match be stopped.
If one of the competitors is injured, it requires only the doctor’s decision to stop the fight. The competitor him/herself or his/her coach may also choose to retire from the fight.
The attending physician may stop any match regardless of it being a World or European Championship or any other prestigious match. Should the attending physician wish to stop a match to examine a competitor, he/she must first inform the referee.
The referee then stops the match until the physician has examined the competitor for the sole purpose of determining whether the fight can continue or not. This examination must take place in the ring and have duration of not more than one minute and any kind of treatment of the competitor is explicitly forbidden.
Should this time not be sufficient, the referee shall stop the match and declare the opponent the winner.
If one of the competitors is injured and the fight is over because of a foul the innocent competitor is declared the winner. In case of an accident the judges must finish their scorecards and the competitor with the highest number of points is declared the winner. If both competitors are injured or knocked out simultaneously, and neither is able to continue the match, fight is over by draw.
Should this situation occur in the first round the match shall be declared “no contest” and no winner is declared.

Giving up (SUR)
In cases where a competitor voluntarily gives up because of injuries or for any other reason, or if he or she does not resume fighting immediately after the intermission between rounds, the opponent shall be declared the winner. In these cases the coach shall throw a white towel into the ring to signal that his/her competitor gives up.

Victory by referee stopping contest (RSC)
The referee may stop a match if a competitor is clearly outmatched or if he/she is a hazard to his/her own safety according to the following guidelines:
a) If a competitor in the judgement of the referee is clearly overmatched and will face unnecessary punishment in the ring the match should not be allowed to go on.
b) If a competitor in the judgement of the referee is unable to continue the match due to injuries or for any other physical reasons, the referee must stop the match and call the official doctor to the ring.
c) If a third KD to one competitor occurs in one round, or if the fourth KD to one competitor occurs in one match, then the result will be the end of the fight by RSC.
No referee can decide how seriously a competitor is injured; he/she must call the doctor.

No contest (NC)
A match may be stopped immediately by the referee before the prescribed time due to circumstances beyond the control of the competitors or the referee:
• The safety equipment of the ring has been damaged.
• The ring is unsafe for use.
• The lighting over the ring is failing.
• Weather conditions force the referee to stop the match.
Under such circumstances the match shall be stopped and a “no contest” with no winner is declared.

Victory by walk-over (WO)
If one competitor is present in the ring and ready to fight and his/her opponent fails to show after his/her name has been called over the loudspeaker, the referee shall signal the referee’s table to start with the running of 2 minutes. If the opponent has not entered the ring within a time limit of 2 minute, the timekeeper shall strike the gong to signal that the match has been stopped. The referee shall then announce the competitor who was first in the ring and declare him/her the winner by “walk-over“.
The judges shall note this on their scorecards, which are then collected. The judges shall then summon the competitor who has won on walk-over to the centre of the ring, and thereafter the announcement of the decision, raise his/her hand and declare him/her the winner.

b) The addition of the scorecards is faulty; one judge has mixed up the corners, resulting in the victory being given to the wrong competitor.
