#1) Is this river a value bet?

$5/$10 NL 6 max. I open from the cutoff to $35 with [7c]. The BB calls. My only read is that the BB called my $35 raise from the BB earlier with KT and called my flop and turn bets with a Txx flop (which had flush draw). I check behind on the river which was a J and I won with my AT.

Effective stacks $2250. Pot $75. Flop [6c][3s]. He check / calls my $50 flop bet.

Pot $175. Turn . He checks. I thought about checkign behind because I didnt want to get check raised off this pretty good hand but decided to value bet $100 which he called.

Pot $375. River . If he had 54 or something like [9c], he just hit, but Ive rarley been check raised on the river at $5/$10. They usually lead the river when they hit so I cant check behind. Do you value bet this and if so , how much?

#2) Is this a value call?

UTG raises to $30. He starts with $448. No read. I reraise to $105 in the BB with KK which he calls.

Pot $220. I get the obligatory [5h][4h] flop. I bet $130 and he calls.
Pot $480. Turn . He has $210 left. I thought about pushing but decide to check and of courrse he pushes. Im getting 3.2-1. Does he push JJ or whatever often enough to make this a value call?

#1) I bet $200 and he called and mucked

#2) I cringed but called. He had [7h] and he missed the flush. Very questionable I think, but luckily I was right.

The problem is when you make your CB and they float you (which they love to do anyway), or you get raised by an overagressive JJ trying to make a steal.
