exactly.

So you flop a set on a HEAVY DRAWY board and you bet 3 into 4.75? Unless you think he's some super aggro guy you NEVER DO THAT. You are just giving him odds and you basically are begging for them to outdraw you.

So, the reason why you bet the turn, but not as much is because you don't want to check and let him know that you are weak. If he raises you too much you can fold, no big deal.

However you CAN check the turn, basically check call it.

But you cannot check the river. You need to value bet it, especially because he has a flush 90% of the time
