<font color="green">This turn card is very bad card and I totally gave up because I put him pocket pair. If I bet I don't think he folding pockets, but also he may raise with higher pockets and force me fold out. On the river I have to c/f anyway if I don't hit my 7-outer. If I hit then probably I can't get any bet from him. So, I decided to check and look what he doing.

He bets but what would be the best play. I folded because I have 7 outs - one four, three kings, three aces and as I already mentioned, if I hit one of them, then probably I can't get anything from him on the river (If my read is correct). But how about check-raising? This bet is too small and it means weak or strong hand and looks like the action end right here. If I raise, he folds or he shoves to my raise and I fold.

What would be the best play here? All comments are welcome!</font>
