I'll plod into this.
While i see what spinoli is trying to elaborate, and it is a point well made, i wouldnt play this style at that level.
Yes, most players dont undertsnad odds etc, and yes enough will call with dominated hands, but position and odds count for a little less at these lower levels. Few if any at 25nl play position, a few more may know about not paying over the top for their draws, but the wont call a pot bet on both the flop and turn whereas as demonstrated they will call an overbet on the turn for the river because omg they are only one card from their flush or straight.
Not to suggest that spinoli is wrong (he has infinitly more experience, br and skill than i) its just that at these levels when they are drawing make em pay. WHen they have second pair and think you have crap make em pay, and especially make em pay when they have Ax to your set or AK/q
Yes they suck, yes they dont know about odds etc, but the profit surely comes from making them pay over the top for cards on both the flop and turn (if they dare) not allowing them free cards to catch hands.
Similarily there is value in chasing your draws becasue they dont hit the pot hard enough when they want to stop draws. They bet an amount on both the flop and turn, without considering how much that bet represents as a percentage of the pot.
Also you are out thinking your opponents here a little. Any one with a set or two pair at this level is going to raise straight back at you believing they have you beat. More advanced opposition will play differently but at this level its more simple.
