hand 1
Kd Jh

tag opens to £8 from co, (seen him steal blinds, called my 3bet and folded to my cbet on a Qhigh flop) I call with KJo from the btn, both blinds call, sb is a solid tight straight foward player, bb is somewhat looser, flop= Qd Td 7h, blinds check to the raiser who cbets £25 into a £32 pot, according to stove i cant raise here, because hes calling most of his range here or re-popping it, I fold thinking that i will have to fold most turns if he bets, both blinds fold, I think the best line is to float here, rep the flush (or re-draw to the 2nd nut flush), showdown if I hit the K and if an A comes it could make him 2pair/set, to win a big pot, definatley worth a £25 cbet IP, did i play this a bit weak-tight?

hand 2
JJ
a raise and a call in front of me i 3bet to £20 with JJ
flop = Q x x, I somehoe end up first to act, i check, 2 chceck to turn, turn=T
i bet £35 into a £60 pot, and get minraise to £75, the other guy folds, ive seen this guy raise with bottom pair before and keep firing, i call, river = J, i check, he bets £85, i tank call (thinking of raising), but dont think he calls with anything worse, can i min raise here for value? theres about £200 behind, but at these stakes river raises = 99% the nuts, there a straight possible and a slowplayed QQ, can i play this hand any diffrently?

please give the HH with the appropriate info. can't answer either of these without stack sizes/position details/reads/etc.

boths hands vs main villain were about 200bb deep eff,
hand 2 the villian was a aggro fish type,

Look at some of the other threads in this forum, and read the stickies for a better idea of how to post hands.

In hand one I'd definitely call the flop.

Hand 2 I have no idea, because you don't provide nearly enough information. Did a tight UTG open and get a caller from mp? If so you probably shouldn't be 3betting here. Was it a loose opponent from CO and a call from the button? Then yeah 3 bet here 100%.

What I can tell you though is that your 3bet is almost definitely too small. If the open was the same as in hand one, 8, then your 3bet to 20 will never get a fold. You don't want to play JJ oop 200bbs deep against 2 players. Taking down the pot preflop here is not a bad scenario, getting heads up vs the fish is not a bad scenario. Getting in a 3 way pot oop is a bad scenario. Up your 3bet size a lot.

As played bet the flop. The Q sucks, but but that's really not a horrible flop for you. It's better to bet here and take down the pot than having to play a guessing game on later streets.

You're stoving wrong. He opened in the CO and c-bet? His range is very wide, there's no way your hand isn't good enough to continue. You should call the flop and see what happens. You're not "repping the flush" by calling, you're repping top pair, middle pair, straight draws, flush draws, sets and two pair - because that's what you should be calling with (maybe not always middle pair).

hand 2 - how much was the raise, what postion was the raiser/caller in? What position were you in (hopefully SB or BB). You need to 3-bet more, assuming the raise was 8 you should 3-bet to 30. The other two cards are important on the flop. Bet the flop. Once you check the flop, check the turn. Once you bet/call the turn and river your set check-raise for value.

Pay more attention when you're playing, you left out a lot of relevant information. If you don't pay attention to that stuff you're not going to be able to make the best decisions, much less get help on this forum.
