Yay we moved up to nl5!

Ok so players get better now and we need to play better as well so we can win.
So in this hand OTF I wasn't sure if I should check or bet.

I check/called because I want to check/call some midpairs that are not that good for betting and also if I only c/c with overpairs then I will lose value with these Overpairs and I will get in trouble if a 5 or a 4 comes on the turn.
But with 56s I have that one covered.

Btw which flushdraws should one check/call on this board? I guess Ah6h is a check/raise but what about AhTh or that kind of stuff? Always bet or sometimes c/c?

ok OTT I improve to OESD+pair and he only fires 1/2 pot so I guess call is good although we don't have much showdownvalue but I thought he may barrel with onecardFD+2OCs.

Ok River we could lead actually... not sure if it will generate enough FE?
Would you lead river and if yes with which reason and which size?
