1. Not a great read on the opp... appears to have picked up plenty of small pots with well timed bets and aggression. I haven't tangled with him in any major way yet.

I am more likely to raise K8s here (that is, if I don't fold it) as I like to be the aggressor in the hand.

Flop is standard as is the call of the wussy-league minraise.

Turn is standard...

Now, do I bet the river on the board pair? Opp called a reasonable sized bet on the turn which makes me consider the possibility of a set.

SB has a weird style. Kinda loose preflop, kinda random postflop. didn't seem overly strong.

I believe I know the answer, but does anyone raise the river?

MP1 has been a bit weird. He's been calling a lot of preflop raises in position and has generally been moderately loose preflop. Postflop, he's been exploiting position with positional bets and bets when an opp shows weakness.

Do you call the river?

How is my line?
