QQ Ownage

you can easily call it off here.he could do this with lots of str. and maybe a high flush.It's  likely with a very small chance he could even be bluffing with a Air considering how low the stakes are and how the opponent could be.

It's pretty much a no brainer call here.

P.S And if he did have AsXs,he would had bet the turn with a certain possiibility.

No,it's not about peeling too loose or weighting your decision heavily,the major leak is that you dont understand how your range looks like to your opponent.

By checking the turn and shoving the river,opponent can think your doing this with AJ,AT,AQ,JK,A9,KQ type hands and all pairs up to 77s.

you need fold equity of 49/(81.5+49)=37.5%. He could be checking the flop with KK,AA all pairs+Ax hands like AK,AQ.All of those beat his perceived range of you.That's about 73% of his range.You have a -ev play.

You must understand how your range looks like to your opponent.It's not about peeling too wide,or checks back turn giving up,it's about your range and his range seen here.

i live around UTC +8 though,so anyone who lives around asia could discuss

Was betting on river wrong? I assumed he could limp with 22 to 99 pairs,and yea 12hands was very little.So i believed he could have nothing much ahead of me and having trips is a bit unlikely(although possible) due to having 2 10s already show up on river,and he would raise turn for the trips,as fish play pretty str.foward.

one more thing that you said he would check raise flop or turn with AJ or AQ.i think with that hands,villian thought process,might be that he wants to extract most value of the flop and turn as drawing spade flushes are unlikely.Most TAGs would rather at NL50 extract value from two pair than get dead money out of two pair IMO.Calling your two barrel,definitely signifies alot of strength,so to assume that he does not have AJ/AQ is definitely wrong.

Lievaai Okay,maybe i should reiterate the point that c-bet after preflop raise wasn't a pretty good idea as he(BB) assumed range had Ace with strong kickers,and J also with strong kickers,so representing a hand there is actually bad.
I get that you bet the turn due to flush drawing outs.But,for a value bet for implied odds,it seems too much.Around $2.50-$3 bet is a better bet.But assuming you bet for the intention of doubling barreling,$4 is pretty strong as it gave him needing a ace pair to call.
River bet is too weak.Opponent will not commit half of his stack just to bluff you,and like wuwei said too many combos in his range beats you.
Sorry i offended you,i don't know that much about your playing style and various hands so i came to that conclusion that you should study more poker and having egos.Playing NL50 is a challenge due to less fish and unpredictable players too.

Why did you lead out on flop? Usually against TAGs,skilful TAGs,you should have NEVER lead out on the flop as the rainbow flop hits him 20/30 of hands(i included middle pairs and drawing hands)So you should have never lead out.
The good solution is that most TAGs will c-bet at least 70% and skilful TAGs will check flop(to lead you to betting on turn.)If BB bets 50% or more of pot,fold.If BB checks,you are lucky.
Turn betting is questionable.The size of your bet was too much for a drawing hand,and worse of all,he could have easily have called your turn bet with better flush drawing hands.
Doubling calling usually for 0.25/0.50 means strong hands.BB in this case is very good at slowplaying you.Clearly right now he has a flush or full house which in this case you are all behind with his starting playing hands.Egotistic if you call your hand,folding your hands the the obvious choice.

7s8s is a good trapping hand to be played passive or aggressive if only you have drawing hand on flop(your choice to play either style).i find problems in everything starting from flop to river. Even though this may sound a bit rude,i think you should study poker a bit more and have a bit less ego to play NL50 tables,it will help you alot in facing situations like these.

sorry i was a bit drunk while writing that post...
l think the worst play is passively playing this hand the whole time overall,so yea,best idea was to reraise 3x1.25(his bet) preflop,and any action i took on flop,turn was totally wrong yea mike,shouldn't have lead out with a bet

Thanks everyone for replying on my hand,i would take bigfiszh's advice to go b2basics.
@mike i raised the flop due to thinking much of his range misses the j hand,but got too egoistic and called reraise :( ,however, with knowing that he reraise on turn,i believed he had at max a J pair and due to implied odds,reraise the turn.With my perception of 6 outs + 4outs
