Example one would be better if the board was rainbow and you could WA/WB the whole field. As is, it's still not bad to play passively but there is nothing wrong with raising to charge flush draws in CO/SBs range.

I thought about this when I made up the hand example and ultimately decided to put up a flush draw there. The trouble is that I think its often better to let an aggro keep firing a draw (which he may well do on all 3 streets). Raising the flop or turn may maximize value against said player if he would try to 3 bet semi bluff, but you have to

1) know that he's on a draw
2) because of this, be able to dump your hand to a 3rd diamond and not fold when he 3 bets a blank.

So in a nutshell, if you were positive he's on a 9-out draw, then putting in more raises is ok. If you are unsure as to his range (i.e. if its weighted towards 9's, 3's etc), then i still think its better to call down on this board.
