So bigger bet on the turn, okay.
It's hard to know how much is really right though.
One could say, the kind of player who calls my turn bet would call a pot-sized turn bet as well.
However, at least I've given the flush draws more chance to play unsustainably.
One could also say by betting pot-size, I'll get more flush draws to fold... But, maybe I want them to call and miss for value. I wouldn't let their implied odds
get there if they hit, because if it goes like this and a third spade falls, I like my hand a lot less...
