Totally agree with ak here.

Also it's worth a bet if you think it's possible to win the pot right there. If you bet and it gets raised and reraised you can pretty much throw your hand away (someone probably has a flush), which is a good thing IMO because it saves you a bet.

Going to the turn in the dark can be pretty costly. In this situation someone may have already flopped the flush and is looking to checkraise. If you check and a blank hits, you probably think you have the best hand and more then likely your going to pay someone off.

Betting on the flop for value and information is always good strategy. You should always know where you stand before the big bets come.
