If you compare this to a typical all-in situation where you have a stack of 10xBB, here you are betting 600 to win 325, as opposed to 600 to win 90 (if the blinds were 30/60). Plus your less likely to be called then if you go all-in pre-flop. So both these facts argue that going all-in is a favorable bet. OTOH, if you do get called, you're probably in much worse shape than in the all-in pre-flop with 10xBB situation. But still, it's not likely your opponent will have a hand he can call with.

However, it's also true that betting a half-pot is a favorable bet, and will difficult for an opponent to call.

Going all-in would likely chase out hands, such as lesser pairs or draws, that might call or come over the top to a half-pot bet. But the half-pot bet doesn't commit all your chips to a hand that missed.
