10NL Rush poker

Hero is ELOH3ll, villain has 5.5 AF on flop, playing
22/19/7.1 (487)

As per the raise preflop, i raise most buttons simply
because of high steal percentage with just a min raise

Preflop: Hero is BTN with  
Kd7c

3 folds, ELOH3ll raises to $0.20, lastusermw calls $0.15, 1
fold

Flop: ($0.50)  
Kd4c8d  (2 players) lastusermw
checks, ELOH3ll bets $0.33, lastusermw raises to $1.00, ELOH3ll calls $0.67

Turn: ($2.50)  
7s   (2 players) lastusermw bets
$1.70, ELOH3ll calls $1.70

River: ($5.90)  
6d    (2 players) lastusermw bets
$10.24

lastusermw returned $1.46

For the river decision.... since he is cring a lot of flops
and draws, im putting him on a diamond draw. However his overbet on the river
inbalances my read a little bit.

I think i should have raised the turn definately though.

What are opinions regarding river decision?

ps: as a side note how do people convert hand histories from
Holdem Manager to have the pictures? Mine wont copy paste.

Cheers
