I wasn't entered in the class so I didn't attempt it and it's not something I teach my dogs so I doubt I would have attempted it even if I was faced with it.
There was only one dog that made it across the #3 jump and it was a huge dog in the Perf. class. The handler stayed between the #1 jump and tunnel, called the dog to her when it came out of the tunnel and sent him back out over #3. He had some hesitation but eventually did it. But this put her too far behind to handle the rest of the gamble and she ran out of time too. Can't remember if he made it over #4. Other handlers that attempted that strategy ended up with the #2 end of the tunnel. Most people tried running downstream of #1 towards the #4 jump and yelling 'Out' while pushing with their left hand/arm. Every single dog came flying over the #1 jump when they came out of the tunnel, none of them even glanced at the #3 jump. Those motion and position cues were far too strong to overide the verbal which is my theory about that 'Out' cue in a scenario like this.
Somebody asked the judge how he expected people to handle it and he said he expected people to use their right arm to turn the dog away back to the #3 jump (my interpretation of her interpretation, it's possible one or both of us misunderstood his explanation so don't quote us too heavily on that). On paper I can see what he was thinking but in reality those dogs came blasting out of the tunnel with such speed that it would be difficult to get that redirect even if you did have a strong off-arm flip/verbal cue (if that's what you even would call it). Again, not something I would attempt to train but an interesting challenge nonetheless. Maybe there are some NADAC folks out there thinking this is easy peasy or maybe it's a good challenge to try to set up even for NADAC folks, I don't know. I've never seen a 100% NQ rate in Gamblers though so I thought it was worth sharing the course for those who like a good distance challenge to practice.
Also, please don't take this as indicative of this judge's courses. His tournament courses were very fun and flowing, similar to the stuff I see in DOCNA. I didn't run any masters titling courses but the advanced/starters courses were very nice. I've shown under this judge before and as I remember his courses were nice then too. If anything this masters gamblers course was an anomaly.
