Arbusers

I get this from rebelbetting.
Marathon 3-way Portland win @ 2.2
188bet    AH      Clippers +1  @ 1.9
There do not appear any other bookmakers at the secondary choise, under 188bet, which seems wierd.
It seems pretty simple and safe, is there something i am not realising?
In the past days there have been some false arbs regarding hockey and 188 that were actually on regular time only and the software matched them up with OT & penalties arb legs.

188 just take it off, is now offering -1 and -1.5 hadicap at clippers

This is not an arb. Clippers + 1 includes overtime.

Thanks for the info man. It did look too good to be true.
Anyway I was lucky cause I did bet a little money there before thinking about it and the "middle" actually hit
