There's this USA soccer game that opened at -140 on the asian books. One guy said the home team is 7-1-2 and the guests are 1-1-11 so it's an easy home win. Throughout the day the price dropped to -232. I avoided the game because I thought it's a trap, there's no way the bookies would put up a stupidly high price like that if they didn't know something. Apperently it wasn't a trap, regardless of how it turns out. I guess checking the w/l ratios is one way to beat the bookie.
