Hi, I'm a 25NL player so not as experienced as you are but I think it will help me to post comments on other peoples hands.

Hand 1:

If SB & BB will prob fold to original Raise then I would call instead of raising pre flop. If flop is rags and Villain bets I would prob call and raise/bet turn. If flop has poss hit Villain (Face cards) I would raise flop and take it from there. Considering Villain is passive and/or tight he prob has AQ+ JJ+.

Hand 2:

On a blank turn I think I would lead with 2/3 pot bet. If its a spade maybe a 1/2 pot bet and fold to a push. Or maybe this is just to transparent at these stakes compared to where I am playing. Anyway thats what I would do!

Hand 3:

Re-raise to $25. Villain prob likes his hand and will call. If he re-raises I'd prob just call and evaluate the flop. If A or K flop then obviously approach it carefully.

Hand 4: I would be betting half the pot here and hoping for a push over from Villain. Possible overpair or lower set. If he has QQ then so be it.

Anyway as I said at the beginning I only play 25NL and all these comments are probably b*ll*cks. Take it for what they are worth or ignore/correct me if my thinking is flawed.

Cheers
