400 nl AK hand. Can you put SB on a hand?

[TopThis]

This is from a site not supported by converter so sorry in advance.

$400 NL(full ring 9 people), I am new to the table so no real reads on opponents other than notes on ones I have played with previously.

SB: ($450)
MP: Hero ($400)
Button: ($90)


*** HOLE CARDS ***
Dealt to Hero [Ah Kd]

MP Hero - Bet $15
Button - Call
SB - Call
BB - Fold

Pot ($49)
*** FLOP *** [5d Kh4d]
SB - check
Hero - Bet $25
Button - Call
SB - Call

Button I have a player note as being a donk. Not worried about button could have anything at this point but after calling the flop bet they only have $50 left so either way I'm not concerned about what they have.
The way SB has played so far I put him on KQ about 50% of the time here, a flush draw about 30% and a set 5%. I think he would reraise to protect his hand if he had trip fours or trip fives. Other random donk type holdings the other 15%

Pot ($124)
*** TURN *** [5d Kh4d] [6s]

SB - check
Hero - Bet $50
Button - Calls and is all in.
SB - Call

So now what do I put SB on? I don't think he has a set or he definitely should have reraised given his position. A good player would fold KQ there. SB has to know I am not bluffing since Button is now all in there will be a showdown. He should now fold other donk holdings such as QQ or JJ there. He may have AK also and is afraid of AA? I would have expected a reraise from him if he held AK to find out if I had him beat. He can't have a King and a flush draw since I have the King of diamonds. It's hard to put him on a hand given that I don't know whether or not he is a good player and would fold marginal holdings in this situation. Maybe a hand like 6d 7d.

Thoughts there?

Pot ($274)
*** RIVER *** [5d Kh4d 6s] [2c]

SB - Check
Hero - ??

any 7 or 3 beats you, and the game is only 4 handed. SB's range of hands could be anything. You need to make a value bet to determine how good your hand is.

forgive me i forgot to say this is a full ring, 9 people. I just chopped the rest out to keep it neat.

also a 7 does not beat me there.

I thinketh SB be chasing...or has KQ. More likely the former.

For the river, checking behind isn't a horrible play, but if you want, you can bet 1/3 the pot for value if the other guy has KQ.

Oooh ok, that changes it. You're good to bet here. Also, I don't even know how I justified the 7, I guess I thought the 2 was a 3 then changed my mind :P

How about my bets?

I did half the pot on the flop to see if there would be any action.
Turn bet was exactly how much Button had left. Wasn't really thinking about SB because I thought he'd fold. $50 wasn't even half the pot there though so I think I should have done about $80.

How much would you bet on the river?

Easy check behind. A smallish bet only opens the betting and the door to an over the top move. Question is if you bet a callable amount and assume opponent will re-raise AND you are prepared to call the re-raise based on your feel/read by all means make a bet.

A large bet likely won't get called unless you are beat.

Check.

this is what i thought also.

I checked behind.

Button shows A 6 for a pair of sixes
SB shows A 3 for the straight.

I believe my mistake was not betting enough on the turn, his gutshot turned into an OESD and enticed him to call.

I can see a loose player playing the hand like he did but A 3 never entered my mind as a possible holding.

Id quickly check behind.

I put him on a flushdraw, so if u bet hes gonna fold cause he knows ur not bluffing ( dead pot), and if he somehow caught taht straght, hes gonna reraise u big and ur in trouble.

So no point in betting, check.
