This was from a game I played earlier today. I'm in third seat with this:





Upcard is the

Score was 7-3 in our opponents' favor.
I ordered the dealer up and went alone.
There are two trouble spots with this hand. The first is if the dealer is void in hearts. In that case, the ace won't walk on a hearts lead because the dealer will trump the ace. This could even turn into a euchre depending on what else he holds but the odds of that are slim.
The other trouble spot is the dealer having a void in the first lead suit (if it's clubs or diamonds) and also holding the ace of trump. This puts him in a pretty good position to take out the king.
Given this, the odds are against this hand actually making the four point sweep but I thought it was worth the risk given the score. I did manage to get the king through (the opponent led the Ace of Diamonds and I played the king - dealer wasn't void and had to play his 10) and turned the hand into a one-pointer but it did not take the sweep. This hand would be a no brainer loner with any other seat position, which shows how hard it is to make a loner from third seat.
Would you have tried this as a loner? If not, what do you think is the minimum needed to try a loner from third seat in round 1?
