Agreed - there are some decent deals to be had, especially if you make them think your a “loser” by depositing and losing while holding the other side offshore.
Usually I’ll play stuff like 2-3 teamers - first legs will be my bets - last leg will be a later event and a large dog. If I’m alive going into the final leg - bet the fave for a guaranteed profit and worst case I hit the long shot and still make a few bucks.
Typically I “lose” get a little tax loss towards the year and continue getting promos for 25% boost or $100 for every $500 in parlays played. Better - occasionally get reup offers from my DK host - today was 25% on up to 1k. Hey - free $250 I can toss on Miami tomorrow night.
