Imagine the board is:
AKQ X J (no flushes possible)

And you have the T

You bet the river and get raised.

Do you push and pray your opponent is a fish and has 2-Pair or something
or do you just call and save some Rake?

I think it depends on the level your playing, right?
Lets say it is $0,05/$0,10

If I know this opponent specifically is competent, then I can save the rake.
If I don't know that, I'll probably reraise. If there's been action, the rake might have been capped already. It's just a pot-odds question when we know all the factors.

I raise against most people at .05/.10.

Tuesday night I raised four times when I was sure it was going to be a chop pot and none of them were, I even stacked a guy on an AA22K board who called with a king.

People are retarded, unless you know that Villian is a conscious, thinking person, raise it every time. The rake is probably already maxed out anyways, and I have to think you're giving up a lot of value if you don't.

It depends on a lot of factors, such as if the rake is maxed out and how competent your opponent is. I suppose at those stakes you're probably better off pushing because you'll get called by a donk with KQ. But against a normal thinking opponent I might be inclined to just call because they probably wouldn't call without it being a chop anyways. Of course, if the rake is maxed out, raise all you want.

I raise or push 100% of the time
