Last night is the first time I've seen this and I question the legality of it because I feel it may fall into the "Misuse of equipment" rule. If you are going for a jump but need to bridge higher than normal is it legal to take your shooting cue, place it butt down on the table with the rest of the cue resting towards your shoulder and use it to stablelize what would normally be an air bridge to make a jump easier. I've never seen it done before but if it is legal it would sure help.
