30-60 party

[The Truth]

Here is a hand I watched a 2+2er play earlier while we were at same 30-60 table on party. I have no stats on the villian in this, the other 2+2 might.

Hero is SB AKo

2 limpers, hero raises, bb and both limpers call.


Flop comes 5d 3s 6s hero has no spade

Hero bets, bb folds, utg+1 calls, other limper folds.

Turn brings a 7d

hero checks, villian bets, hero calls.

River brins the Kc
hero checks, villian bets, hero calls.

My question is this, if the king doesnt hit the river, does hero still call? I imagine if the board straights hero calls too, so he is getting odds to draw to straight or a pair. Also, why not bet the turn on this drawy board.
