some confusing spots at 2nl/5nl

hand 1 i would either lead close to pot or check/raise a decent amount on the flop. typical 2nlers do not spot sets, and tend to be focused on their own hands. i doubt he folds any of 66-AA, or any Ax he has in his range to a lead or a check raise on the flop. actually i think i prefer the check raise because he's going to be betting this flop a heap and your hand is very strong compared to his range. your turn lead is good, but would have been better had you been able to bet 24 into 30. river as played i dont like. he's probably not calling a potsized bet without a straight, 44,55, or 99. i think i'd bet something like 30 hoping to be called by 77,88,99,A9,TT+ (if he ever has them) and folding to a raise because i doubt he's turning anything into a bluff here.

i'm too tired for hand number two at the moment. i'll come back to it. oh, and in answer to the last bit, the more information you can give people on your opponents, the better they'll be able to try and help you determine the right play. any reads you might have from past hands they've played, or their stats from your tracking software, how much they bought in for/whether they top up when they lose a pot (regs typically do this), anything which might be slightly indicative of their playing style/tendencies. i understand your PT3 wasnt working for these ones so thats fine. just for future reference.

Definitely try to post more reads on the villains involved.

Hand 1 looks like a bet/fold, or a check/fold if you don't think you have the discipline to not bet/call a shove. The obvious draws got there. Definitely raise the flop and raise it big, villain isn't going anywhere if they have an ace, 6 or overpair. If villain doesn't have anything they can continue with you were only going to win a small pot anyway, and if one of the biggest leaks at these stakes are people call/chase too much, start taxing as early in the hand as you can.

Hand 2 fold preflop, this is such a high variance spot and you're going to be lost on so many flops. As played either check back flop or bet smaller, bet/folding the turn to avoid river spots like this - if you're raised you can fold, and villain may check the river to you allowing you to show down for free. Betting the flop smaller would also let you bet less on the turn than your chosen bet would have meant. Without reads I fold the river and don't feel too bad about it, we just don't know enough to call.
