I've been trying to fix a leak in my game, which has been paying people off on the river. Here are couple hands I recently played that my experienced poker buddy would have played differently than me. Any thoughts would be appreciated.

Game is 3/5, 7 players.

Hand 1:
Hero in SB with KdTs
$10 straddle
Button limps
H calls. BB calls. Straddle checks.
Flop Kc Ks 9c
Check to Button who bets $20.
H raises to $60.
Button calls.
Turn 6c.
H checks. B bets $130. H calls.
River 2s.
H checks.
B all-in $330. (H has B covered.)
H ?


Hand 2:
Effective stacks $800.
Hero in LP Ac Td.
$10 straddle.
H opens to $40.
Button calls.
Flop 9c 5h 4d.
H bets $40.
B calls.
Turn 10s.
H bets $80.
B calls.
River 8s.
H checks.
B bets $205
H?

H1 Fold pre. River is a fold.

H2 Bet flop smaller, fold river.

Thanks!

I folded both hands on the river.

For H#2, V showed a 7, so he possibly had 76.

First hand is a fold on river. Seems okay other wise.

Second hand I think I would fold river. I can't really think of a lot of natural bluffs. Not a good flop for us to bet our hand.

H1 -

PRE - Raise or fold. Don't limp from the small blind. KTo is mostly a fold, but if BB and straddle over-fold in this spot, we can occasionally raise.

FLOP - Start with a 1/3-1/2 pot bet, not a check. If you're going to check-raise, go bigger, at least $80, if not $100. But better to just bet out for 1/2 pot.

TURN - Keep betting. He shouldn't have called our flop x/r with any nut flush draws. Yes, he could have some better KX, but a lot of his better KX would raise pre or 3B flop. He could have some 9x, and some non-believing PP's, or some unpaired Broadway combos/draws we could target for value.

RIVER - Yuck. If we bet flop, got called, and bet turn, and got called, I'd probably check to induce a bluff. As played, I kinda hate folding, because our hand is so under-repped, but I can't figure out what worse hands would bet here when we x/r'd flop and c/c'd turn, so I guess fold.

H2 -

PRE - Why open to $40? Why not $30. Otherwise, it seems fine.

FLOP - just check. Call if he bets small. If you're going to c-bet the flop, go bigger when heads-up and OOP, like 2/3 pot.

TURN - size up with our bet. Betting $80 into $180 isn't going to get it done. Bet at least $120, if not $150.

RIVER - Yuck. Fold.

Problems I see with both hands:

1. the hand selections of KTo and ATo, combined with our actions, are not great. In a three-blind structure, we should probably just fold KTo. Opening ATo in LP is marginal.

2. We're not following through with our flop aggression on later streets. If we're going to check, I'd rather go check-bet-bet than bet-bet-check or bet-check-check. In hand 1, x/r'ing flop and checking turn and river looks like we're giving up with weak KX. In hand 2, we let V realize his equity cheaply by betting so small on the turn.
