Legal yes. Lame yes.
Last time they did this to me was Pro Bowl last year. Total was off by a couple pts
and I liked that side so tried to bet $500. Long pause then informed that line has moved
2 pts and I can have it at that number. I passed and since then if I want a bet and I'm
pretty sure I won't get snapped off by another bettor, I just milk it in. $200 at a time
until I get my fill. It's not what you want to do to stay in a books good graces but since
they've already laid out the ground rules, it's fair to react accordingly.
