Why it is not mandatory to call a raise after completing.

[milesdyson]

you should complete with T7o against the guy i described (yes in a 1/2 sb game). you see a flop for super cheap against a guy who will usually give you at least another small bet postflop by peeling every flop. if he hits any piece, you usually gain much more, and it only costs you half a small bet to see a flop. plus he is probably not tricky at all, and you can get away from your hand very easily if faced with aggression.
