I am a poker player who makes about 4 bets a week, just for some fun and also for entertainment while folding. I usually bet just enough to get 100 back and never bet + lines. I have my own little system, it doesn't offer much action, but I haven't lost a bet in about 2 months. This is all irrelevant. My question is this; I read a lot in the handicapping forum about people putting their own lines out and seeing how the book sizes up. I see how this could be fun, but what is the value? Also suppose I think yankess should be - 180 and the book lists it @ -160, is this good or bad ( ie do u bet it?)....thx...
