I feel like I'm one of them after looking over this. I thought the preflop raise would give me enough fold equity to lead into two players despite the overcard. Then after one called I switched into check call mode. Is this to passive?

No. Check/call is iffy with so few bets in the pot.

But it is .05/.1...

I normally bet/fold the turn. There are still a few things that you beat that will call you. If you get raised let it go.

River I would check/call against aggressive players and check/fold against passive players.

I think you should keep betting until someone raises you. This applies when your PP is higher than mid board pair, or when you flop mid pair. If people just call you, they are often drawing.

What draws do you see out there?

Was I right to lead the flop?

After leading the flop should I lead the turn? It seems that the turn check screams weakness and that the other player would be right to bet into me with damn near any two cards.

With the pot laying me 8 to 1 on the river is a check/fold still the right play?

At low limits, many players would consider Ax of clubs a draw. But I was speaking more generally. Players draw to a lot of crazy things, though.

A read helps on the river line.

Definately bet the turn, though.

River, call against an unknown player.

Was I right to lead the flop?

Yes

After leading the flop should I lead the turn?

Yes

It seems that the turn check screams weakness and that the other player would be right to bet into me with damn near any two cards.

Correct

With the pot laying me 8 to 1 on the river is a check/fold still the right play?

Do you believe you'll have the best hand one time out of eight?

Yes, lead the flop and the turn. It is hard to fold this river without a read on the BB.

Yes to all; those are standard.

It's the 5 to 1 on the turn, which (figuring a river bet), is effectively 3 to 1 (6 to 2) that I fear.

that turn check/call is so vaginal. bet it out and fold to any aggression[/b]

After leading the flop should I lead the turn?

Yes, allthough there's something to said for inducing bluffs from AQ or whatever.

Not a lot to be said, but something.

i, for one, think that turn check blows whale cock.

Line is b/b/b if it keeps being just called.

If it's raised on the turn particularly you have to consider folding.
I might or might not call it down...it is a bit of a gray area
