Once upon a time I understood this game, but I'll give it the 'old scrub poker try...

1. Fold
2. Make it $3 or $4 to go. Check the turn unimproved. If re-raised, go all-in and hope it's 3-way.
3. Bet $6, fold to a raise
4. Cry and call, pot is too big. Try to get your money in faster with Aces up.
