One play we used at 10u on the offensive side of this situation with less than 2 outs was to have the runner at 3rd get their normal lead on the pitch, batter/runner jog to 1st make the turn and jog to 2nd never changing speed. If the other team tryed for the out at 2nd the tag had to be applied, this gave the runner at 3rd the chance to score. At 10u very few catchers will be able to make an accurate throw to 2nd or resist the urge to try, but if they do try we just scored. This will work more times than not because very few team practice defending this at 10u. And yes I will give up an out for a run.

I am confused. Why would the catcher be throwing the ball to 2B? The pitcher should have the ball after a walk.
