My partner was one of the boys from school, who took a basic librarian, two tactical squads (one with plasma and the other with a missile) and 5 bikers. 'Look out, Sir!' seemed an appropriate team name for us!
Our store had made a deliberate effort to get more of the younger players along and actively encouraged mixed pairs of an older and a younger player. Other stores seem to have also been wanting more young players, as two of the three teams we played were both kids, and the other was two brothers, including a young teenager. That might have had as much to do with our results and with the fact that it was a weekday during the school holidays. Because of my school club, I am quite used to playing kids anyway.
Our first game was against a nids / DA combo against a nice couple of lads. The winged Hive Tyrant proved particularly troublesome with Iron Arm meaning we could barely scratch it. However, we made a few rules mistakes, like letting him zoom across the board on Turn 1. Very silly! My biggest error was believing his gaunts on the 4-point objective were fearless, as long as the tyrant was on the board. It was only in about turn 4 I realised they were actually out of synapse range, when I couldn't do much about them. We lost 8-4.
The second game was probably the most enjoyable, as the elder brother knew the rules, which helps! They had a Plague Marine / Thousand Sons tag team we played length-ways with two objectives. It ended up as a draw, as two Thousand Sons managed to keep out of combat on the last turn and got onto their objective. We would have won, if we had made the charge and tied them up.
After a loss and a draw, the last game was a bit of a reversal, but was not the most satisfying victory ever. We were up against two more kids with GK and DA (a lot of which were unpainted). The GK player had a Dreadknight, librarian and two small power-armour squads. The DA player was nowhere to be seen for a few minutes once we started setting up, then he turned up with Sammael, 3 squads of bikers and a razorback. He was surprised that he couldn't take the razorback without any infantry, as was I that nobody in the first two games had noticed!
We basically stood back and let them advance towards us, with only my jump squad moving to meet the bikes, which they managed to pretty much tie up for most of the game. He only remembered late on that they had Hit and Run. The Dreadknight almost managed to make it into combat before being shot up, largely by rapid fire, and then the rest of the GK folded. It was then just a case of grinding down the DA bikes, including killing Sammael with a lucky snapshot from the MM. In the end there were only two DA bikes left and most of our army was still intact for a 10-2 win.
With 15 points for a win in the last game and a decent painting score, we ended up 9th, which was a pleasing standing, especially after our first game!
