All share close body contact and use the hips, albeit in the pure end member throws in a distinct manner.
I'll write what my understanding of the throws is:
O Goshi: Hip acts as a "scoop", arm around waist does not lift, only pulls uke in tight. Alternatively, the hip can act as a block to roll uke over by twisting the body/lifting a bit with the legs.
Uki Goshi: The key here is the "float". Hip entry is shallow (I was taught it is a "half hip" throw, whereas O Goshi is a "full hip" throw). Throw is done with a special kind of twist of the hips, body, no Lifting involved with legs. Close body contact is needed, but it is different than O Goshi.
Tsuri Goshi: So we all know what Tsuri is, to lift from above like a crane, as in tsuri te, Tsurikomi Goshi, etc. You use your arm/hand to grab the belt and apply the tsuri action to help throw uke. That would be Ko Tsuri Goshi. If you grab over the back, high collar, etc., it would be O Tsuri Goshi. I was originally taught that you could do O Goshi from a collar grip, no arm around waist, and do Tsuri Goshi from the collar grip as well. I'm not sure that's true now though, technically. I guess if you did an O Goshi hip action but did not use any tsurite on the collar, only used it to pin uke to you, it could be true.
Those are the "pure" end members. Of course, they get mixed up in actual randori or shiai a lot.
"uke goshi doesnt lift like Ogoshi does... why? maybe becuase sometimes the opponent is either too big to lift or tori isnt capable of it or perhaps just becuase uke moved sideways and slipped off a bit."
Right, in actual application those are good reasons you might end up in Uki Goshi after starting an O Goshi or Tsuri Goshi. The hip and upper body action of Uki Goshi is pretty distinct.
all the same, if i practice only a basic ogoshi and am in randori there are high chances that, without knowing either of the other 2 throws, that i could do them while attempting ogoshi only."
I agree, Josh.
"they are such a close-knit family of throws that i dont think you need to practice all three of them hundreds of times to be able to use them.. i think if you have a good ogoshi that you can easily use the other 2 and begin moving to uchimata, harai and hane..."
Sure, I don't think it would be wise for somebody focused on competition to practice all three hundreds of times. O Goshi is the most basic of hip throws, so that would be the one to focus on. YOu could work "variations" off of it depending upon what uke's reaction was, and would end up with throws that look like or are Uki Goshi and Tsuri Goshi.
"BTW.. did you ever notice how often 4-10 year olds will do uke-goshi while attempting Ogoshi..."
Yeah, I have. It's funny, because you know they haven't a clue as to what they just did!
