Not sure I agree with you on this article and here's why. In your example you give lets say the guy has what you say - nut flush draw (12 outs). If you bet your entire stack (200 into 235) he would need 45% equity which he isnt getting so if he calls that good - a mistake by him and he may call here but probably not if hes a good player. Also he probably wont if hes on a naked flush draw (9 outs). If you bet 1/2 pot like you mentioned (125 into 235) he is much more likely to call getting 2.88 to 1 and he knows hes getting the other 75 in your stack so hes basically in for 200 to win 435 - again 45% but he doesn't have 45% equity with one card to come and 12 outs. So by betting less you are forcing him to MORE LIKELY make a mistake on the turn which is what you want vs him CORRECTLY folding. See what I'm saying? Yes there is an argument for just getting the money now but I would think in a cash game betting less here is the correct play in the long term.
