If its a good technique/combo he can't stop it anyway you fake and fient and it looks like something else but he still end up getting hit with the same combo.

Now after years of training with the same guys they figure you out, but not the newbies even if they see you use it on someone else.

Its more then just techniques its setting it up like mentioned its like a mind game. 70% mind, 30% technique.
A list of 5 you still don't know when or where they wil be used.

lol
theres that 70/30 rule again.

ok... these are a few that come to mind, probably my favorite for "stand up style sparring". My MMA style of fighting is similar but I don't like to leave the ground or have my back turned toward my opponent, there are to my times you can be dropped or taken down.

1. Left jab right straight punch with a front kick
2. Fake front kick cresent/axe kick.
3. Fake side kick spinning back/hook kick
4. Round kick reverse punch
5. Spinning back fist.

Nothing fancy but they work for me.

Dang, Schanne! Quit peeking at my list. I see you and I can't spar together. An hour later, no points scored!

1. Back fist or forward punch to the head
2. Back fist followed by reverse punch
3. Counter reverse punching
4. Snap forward leg round kick to the head or lower abdomen
5. Forward leg hook kick to the head

Combinations of the above. I use front hand ridge hand like a left hook to finish many of the above techniques.

These are a few

1 Quick backfist followed immediately by a sidekick.
2 Use front hand to knock/deflect opponents front guard down followed by reverse punch to head
3 Multiple quick jabs to head. Really tests your opponents guard.
4 Lunging hook
5 Cresent kick to knock their guard down followed by lunging jab.

I like kind of simple stuff

1. a jodan jab, and immediately following with yaku-tsuki
2. a half yaku-tsuki feint that I quickly rechamber and turn into a head level ura-shuto (no contact allowed on this one though)
3. jodan jab, jodan yaku-tsuki followed by chudan geri with the same side foot I threw the yaku-tsuki on.
4. simple ankle sweep with followd by a jodan jab.
5. smacking my opponents hands away and then going into the starting position of a side kick, from which I'll throw a side kick, crescent kick, or a simple backhand depending on how they react to the hand smack.

I guess after reading back my favorite 5, it looks like I just like variations of a feint and then single hard attack.

For me I don't feel like I have favorite techniques or combinations while I'm engaged in Kumite. I just tend to react accordingly to my opponent. If I have to say a top five it would be strategy's I use instead of certain techniques. Again these strategies depend on the type of fighter my opponent is.
So lets just say for the top five techniques, would have to be the top five basics.

Lol, my favourite five? Um, I guess that would be:

1) Flicker back fist jab/regular jab: I use this like almost all the time. Just use it to push back opponents, stun them or use it as a starter to a lot of my combinations.

2) Cross/short reverse punch: To me, it's a very good move to use. Strong, fast and can be used many times. Use it alot in sparring as well. Lol.

3) Front Kick: Most favourite kick of all. Imho, no kick beats this, both front leg and back leg. Very fast, strong, and best of all, one of the least telegraphing kicks. I use this in sparring a lot. You don't mess up your stance as well.

4) Roundhouse Kick: One of my other favourite kicks. I tend to use the front leg to avoid telegraphing and lag. However, if the opponent is really pushed back, I usually go for the kill, sending one really hard back leg roundhouse. Nice kick though.

5) Vertical/Horizontal Hammer Fist: I use this when I'm charging or when the opponent is charging. I charge forward, then quickly shift to the side of them and go for a horizontal hammer fist to their solar plexus, face, or both even. I've been doing the vertical one when I'm charging. I do a jab then a quick hammer fist to the face, controlling of course lol... sometimes I may shift to the side and do a half uchi-uke block/hammer fist (being used as an attack).

6)... If I was in real fight, I would use a lot of elbows and knees... I'm somewhat quite good at them, especially my elbowing strikes.

So yea that's all lol.
