12 days 50nl in .th

I started playing poker in the middle of this month because i rented a house and got my internet working a few days later.After a breakeven-swing at the first two days i returned to my normal game and was able to keep my 12bb/100 up.
Most of my hands were boring abc-poker stuff but i found one spot were i think i could just call the river donk.

I know about him that he is a 24tabling fishreg from china with a 8% (15 situations 2-3handed) fold to cbet who plays really bad. Pre and turn are standard, i also might reraise the flop because he got so many crap in his range, but i decided to call because the fd made more calling hands possible. His riverdonk looks so weak that i pushed for value because i think he got more ofthen trips than a flush or fullhouse witch he cant fold.
