I just start and play for only 300 hands it could be my bad day and already down 2 buy-in. I decide to stop and post this 3 hands rather than play Tilt and lose more.
Hands 1:
The reason I fold Nut straight because the river pair the board and I think Villian have Fullhouse.
Villian I have no read yet but with big stack. I think Villian raise with QQ Raise 3 then when he hit flop try to get more $ out of me therefore he only bet $2 flop.

Please tell me which is better way to play these hands.
Thanks

Hand 1... don't call a raise OOP w/ a sooted one gapper... When you hit, raise him the pot... As you played, you gotta raise the turn a LOT more...

Hand 2... reraise PF... As played, raise the flop and try to get it all in...

Hand 3.. check/minraise = supermonster... Fold to his flop raise...

Get more aggressive with your big hands and they'll hold up more...

I just finish my session very lucky me. from 2 buy-in down and I'm back up by +1.2 buy-in.
I have 1 more hand here really confuse.
Villian is Maniac he raise very often.
I though for sometimes and decide to fold my over pair. are there better way to play this please

If he's a maniac and raising often, reraise him PF...?

That's why I'm so bad. in my mind was try to limp and take him out with a monster. after the session was over I still can't take him out.... wrong way of thinking = wrong result.
Thanks MVPsport I'll learn and try to reraise more often against Maniac .
