Thanks a lot. It's nice to see Grozer sen., a young Liefke and of course Hee-Wan Lee playing!

Is there in Poland any limitation how often one team can ask for a "challenge"?

I know what "quote" means. Dont know why you think i wouldnt?! :-) To be honest, thats not enough for me. Every source - german and english - i could find to this topic, tells me that the blocking attempt is allowed and just the touch is a fault. Even our offical national rules explanations says specific that the blocking attempt from a back-row player is allowed! The problem with the 4 blockers is clear but if you see something like this just hit the block. Then its definetly a fault... ;-)

Could you give me some rules quote? I am always a little sceptical about half knowledge thesis without any evidence. As I said, I think its possible that the blocking attempt is a fault too but I couldnt find any rule about this...

Hihi, no problem. Things like this just happens when two non-native speakers tries to discuss... :-D Well I lernt a lot. Its a long time ago since I looked in the official rules that much. ;-)

That this action is a fault is clear. I told that some posts later. But you wrote that the blocking attempt would be an error too. This is wrong! Just the completed block from a back-row player is a fault. A blocking attempt from a back-row player is no fault! Edit: Just a Libero is permitted to attempt a block. A back-row player is allowed to be part of a blocking attempt (but not a completed block).

Participates means that the player is part of a block. In this case the player is part of a block which is completed (one blocking player touches the ball).

Yes, 14.1.2 tells us what a blocking attempt is but 14.6.2 discribes that only a completed block (a block with a touch) is a fault. So it should be legal to block as a back-row player if their is no touch from the block! Their could be another rule that makes this permitted which I dont know...

I think your wrong Someone. The official rules dont say anything about the blocking attempts from back-row players. I also thought it would be a fault but it seems to be legal (to attempt a block as a back-row player if no one in this block touches the ball).

Rule 14 on page 27++

Well I'm not sure about the french rules in their leagues but after FIVB rules it would be an error if any blocking player touches the ball. Blocking faults: 14.6.2 A back-row player or a Libero completes a block or participates in a completed block. The back-row player participates in the block so it should be a fault (if the block touches the ball)
