No reads whatsoever. After flopping the nut-straight I raise the pot after 1 bettor and 2 callers. Should I have bet more To chase out flush- and straight draws? Just shove it right here?

On the turn a scarecard falls, giving KQ a better straight. I bet again to find out if this card has hit anyone. A lot of action and now what?

preflop... ugh! you should be folding this - 98o is a crap hand. If you want to play it, raise it up and show some strength over the limper ahead of you... but better yet don't play it at all.

flop... that's OK

turn... dunno - at these stakes, the players are so terrible I probably can't fold here. You're going to see 2 pair, sets, and a chop as often as you see KQ IMO.

Preflop, easy fold, complete junk.

Flop, when action comes to you there is now $3.30 in the pot. Your reverse implied odds suck on this hand: future cards can only hurt you. So make at least a pot-size raise: your $0.60, making the pot $3.90, plus $3.90 more. So you raise to $4.50, *minimum*. The raise you made is far too easy to call for implied pot/implied odds.

Turn blows, but folding is the right play. Don't know if I could though.
