Need some competition tips from you Judo guys !

Practice how to proper fall so you dont get inyured. Besides that work on your foot work and you will be ok

When it comes to throwing, one of the things to always keep in mind is that, when you throw, the person has to be coming into you... and that works both ways, for you to look out, and the other way around. It was always rule #1 in my book, and still is.

When defending shift your hips away from the direction he is attacking from while maintaining good control, as if to block his hip with your own. If you are too slow though in defending or resetting you stance it can set up ippon seonagi for him. If you get this "block" it opens up a world of counters and if you have good grips he will be really off balance and most leg sweeps should do the trick. If not just keep him moving and threaten with a lot of reaping throws like Uichi-gari. Throws like that tend make less experienced Judoka hesitate.

I found a lot of success even against black belts if you can control their hips. You feel an attack is coming ground yourself and check the hip with your hand. If you are holding a high grip, don't leave out there because he might get under it and slam the sense out of you. If you can respond quick enough, it interrupts their rhythm of attacking and it's just all about control and off balancing them. Ground game in Judo is difficult, and I wouldn't really rely on it less you are great with positioning on the ground. You have to act at a much quicker rate since the rules are only 8 seconds to achieve a dominant controlling position and maintain it for 25 second to score the full Ippon, less you scored already with the initial throw. And always getting caught in full guard since it's considered a neutral position and you will be stood up. If you find yourself in a position to use submissions, stick to the Ezekial chokes since they can be set up from damn near anywhere and it should game over for them. I hope this helped. Good luck with you competition! You got this!

There is no set time for limit on the ground its about progression, always work toward putting them on their back or a submission, working towards a pin will generally give you a bit more time in the progression. Even if you have a sub locked in, you need to finish. You can be stood up with a armlock extended if you aren't finishing it right away.

Awesome, i'll be sure to take as much of this as i can on board!
Chris if i remember correctly you're a Judo black belt right?
