New Rule for 2023-24

• Two feet may be the supporting points this year.

• One foot plus a knee or a different body part may be the two supporting points even if from same leg. 

• However, pinning may only occur if something other than feet are the supporting points. 

(a) Is it true that one wrestler with both his one knee and his toes from the same leg inbound will declare the match as "inbound"? 

Correct, remember the rule change adds fee/Toes to the list of supporting point, you are required to have 2 points inbound, there is no requirement that they must be on the opposite side of the body, you could technically have multiple times when 2 supporting points could be on the same side or leg (i.e.) buttock/foot, knee/foot, side of the thigh/foot, etc

The requirement is 2 supporting points.

(b) When trying to "pin" an opponent, does the opponent's shoulders have to be inbound, or may his shoulders be out of the circle as long as the offensive wrestler has two supporting points inbounds such as both his knees?

Opponents' shoulders can be inbounds or out of bounds, in either situation, near falls points or falls can be earned, remember in a pinning situation the scapula or any part of the shoulder of the defensive wrestler become supporting points.

Per Rule 5-15-b When the defensive wrestler is on the back while the supporting points of either wrestler are inbounds wrestling shall continue. In this situation any part or the defensive wrestler's shoulder or scapula is considered to be all of the supporting points

If you read  rule 5-15-C Inbounds you will see that "Near fall points or a fall shall be earned only while the supporting points of either wrestler are inbounds In a pinning situation when all parts of the defensive wrestlers shoulders/scapula are on the mat beyond the boundary line, the feet including toes and heels of the offensive wrestler are the supporting points, The offensive wrestlers knee (s) must be inside the boundary line, whether in contact with or above the mat.

Per the interpretation the new rules allow the offensive wrestler to be inbounds, points can only be scored if the knees remain in bounds. This new rule adding feet will allow the offensive wrestler to remain inbounds and continue to work for back points or a fall, if the knees go out by working to bring the defensive wrestler back to the wrestling area, so the offensive wrestler's knees are inside the boundary line. 

In years past when the offensive wrestlers' knees when out in this situation, the situation ends.
