$0.50 NLHE STT Turbo: top pair on the flop, scary turn, and 2 pair on the river.

Very Beginning of the 9 handed sit go.
My opponent is unknown.
blinds 10/20 Everyone has almost the same amount of chips (1500).
Whole table folds to
Me sitting on the cut off with
I raise 3 bb to 60
Button calls
SB folds
BB calls.
Pot 190
Flop
bb checks
I bet from the cut -off 2/3 of the pot 142 ( I bet with what I'm thinking might be the best hand and to not give any opponent free card to catch 3rd diamond )
Button calls
BB folds
Pot 474
Turn
I bet the flop 474 ( I bet to avoid giving him a chance to bluff me on that ace, and also to make him throw away pair of queens , pair of kings or even pair of twos. Is this thinking ok?)
button calls
pot 948
River giving me two pair .
I shove. 804


Should I bet higher on the flop and why ? is there a better option than betting the turn out of position? What about my shove on the end ?
Thank you for any useful comments.

I wouldn't be opening this from the CO in these games. The questions you ask are hard ones to answer as you put yourself into a spot where you can win only a small pot and if playing for a big pot you can easily be outkicked or outdrawn.

So while i don't much like the open, the flop bet i don't mind since we can get value from Qx type hands. What i would have done is bet a little bit under half pot, this is due to the fact we still have a pretty hard hand to play, Obviously if the button folds were in much better control (but we don't know he will fold when we bet the flop) but since we are OOP vs one player i keep it smaller here rather than bigger. On the turn i would slow down quickly, but i wouldn't neccesarily check, i would just make another very small bet, almost the same size as the flop bet, this is just a basic blocking bet designed to get us to showdown cheaply, if he raises us i think we have an easily decision by folding rahter than checking and allowing him to bet a large amount and take away our control.

So my betting pattern in this spot would look like this..

Riase pre to 50 (making the pot on the flop smaller
pot 160, my flop bet would then be around 60 chips when the button calls the pot is now 280 (compared to 470ish)

Now my turn bet would be around 100, when he calls the potis then 480 on the river. Now when we hit our card on the river we can bet big for value, or we can bet small again for value, or if we miss out gin card we can also just check keep that pot small (not allow him to raise us off the hand) and the maximum bet we will usually be facing is around 400 chips, but the key is that we're not putting our whole tournament on the line in one pot. It's early, we can't win the tournament here and winning pots early is insignificant when we can pick up more chips by just shoving in a BVB spot in the late game vs players who fold too much.

So key thoughts here, stop raising so much early on, just chill and wait it out until the blinds are big then put your raising shoes on and pummel them will really loose raises and shoves in the late game .

Just to give an example of what i'm on about. Preflop here winning the blinds is like 30 chips to us, risking 60.

Later on, at say 100/200 we can risk 400 to win 300 with a much higher success rate. So try and stay out of early conflicts and then expand your opening range later on in the game and really pummel peoples blinds as you are rewarded far more for your efforts... The cool thing is at your level, most people get scared (even if they don't admit it) in the late game and will fold far more often than they should, so wait it out more, get to the mid-late game more often and will in turn cash more often, get more experiance cashing more and in turn win more games which of course means more money

With stack 75bb fold preflop, very often you will be play against dominated range K8+ or A8

Postflop game... In flop standard cbet and your sizing is it fine game because board coordinated and we OOP.

In turn you need pot control, because we OOP and villain can have Ax or K9+, if we bet now villain fold all draw hands, but call only with best hands... It is better to check and give him a chance to bluff in river if draw not closed...

In river we must shove because we bet turn and draw not closed....Villain can call with Ax or Kx he might think that we miss draw and we are trying to bluff..

Very good information from you fellas, I will adapt my game to the reccommendations and see how it goes.
BTW Villian called my all in on the river and showed AQ and won the pot.

if he had the ace and if he is a good player he would shove the turn no matter if you bet the turn with the ace, actually a better player would reraise you the turn with any two because once you bet the flop and then the aced turn it was quite obvious that you were bluffing at some point,

by the other hand i dont see what´s the point to try to steal blinds the first hand with K7, i prefer to skip this one
