Here's another one I thought I'd tee up:
(If my hypothesis is correct, pattern Sam-Il underwent significant change between versions of the book.)
Move #3 in pattern Sam-Il:
"High side block with knife-hand" or Knife-hand high block?
Move #8 in pattern Sam-Il:
"Low block and outward forearm side block" or Low block and Back-fist side strike?
Move #16 in pattern Sam-Il:
"Low sweeping kick" or inward crescent kick at mid or head level?
Move #22 in pattern Sam-Il:
"W-shaped block with a stamping motion" or Mountain block with a regular step?
Move #29 in pattern Sam-Il:
Punch with fist at the shoulder in L-stance or 9-shaped punch in sitting stance?
Move #30 in pattern Sam-Il:
Forearm inward strike block or circular middle block?
Some fundamental terminology is in order. (Note: how General Choi defines certain terms in the text i not always the most common every day usage) If a technique is "Side" that specifies the stance is either Half or Side Facing (Vol III P 220), if it is Front it is full facing and tool is at the Center Line (Vol III P 214 -later editions use the term Solar Plexus line and Not Center Line)
Move #3 in pattern Sam-Il:
"High side block with knife-hand" or Knife-hand high block?<<< This is a text refinement to denote a Half Facing stance by using "Side Block"
Move #8 in pattern Sam-Il:
"Low block and outward forearm side block" or Low block and Back-fist side strike? <<, Both the 1965 Book and Vol XII state both arms are Blocking. Vol XII High Block to D with Right outer forearm and Low Block to C with Left outer forearm - L Stance.<<< Since L stance is always half facing, no exceptions, no need to state "Side Block"
Move #16 in pattern Sam-Il:
"Low sweeping kick" or inward crescent kick at mid or head level?<<<<<< 1965 Text call is a "Tackling Kick" which was re named sweeping kick as it appears in the encyclopedia, so it is done to the ankle joint. 1965 Book has Crescent kick - same as later texts to Block the hand Similar to "Hooking Kick" found in Ju Che and is used to follow with a consecutive kick attack per 1965 Text.
Move #22 in pattern Sam-Il:
"W-shaped block with a stamping motion" or Mountain block with a regular step? 1965 Book and Late use stamping Motion W shape Block. Just as the name "W" follows using the Similar shape to our alphabet "Mountain" followed the shape of the Chines Character used for Mountain so that name is used for this shape block in many systems.
Move #29 in pattern Sam-Il:
Punch with fist at the shoulder in L-stance or 9-shaped punch in sitting stance? <<<< 1965 Text and Encyclopedia are similar . Encyclopedia " Execute Middle Punch to c with Left Fist while maintaining a left L Stance toward c Bringing the right fist over the left Shoulder. Not sure what you mean by "Punch with fist at shoulder" But per Vol !!! P34 L Stance obverse (Rear Hand Punch) the fist is in a line that runs parallel to the other (Lead) foot. So, whether the fist is closer to Shoulder like, Chest line or Center line would be a function of shoulder size and arm length.
Move #30 in pattern Sam-Il:
Forearm inward strike block or circular middle block?<<< Both the 1965 text and Encyclopedia call this a "Front Block" (Not Circular) this is important because as noted at the beginning of the post this tells you it is full facing and to the Center line. The term "Inward" as used n the encyclopedia denotes not just the direction from shoulder line toward center line (Which can apply to a "Front Block" as used in the text) but also denotes the Block is to the Chest Line (As opposed to the Center line)
