Kxs big draw hits, semi deep

Guy is 61/37 after lots of hands. I've been using my position against him reraising pf a few times and raising the flop a few times and he's folded every single time he got met with resistance. How much on the river? Effective stack on the river is $51.25.

I'd just push the flop. You'll be hard pressed to get more value out of your hand as both your draws are obvious. You're a 3:2 dog against a set, flipping against 2pr and a nice favorite over 1pr hands.

As played the turn card sucks hard. You've put yourself in a pretty shitty spot by not pushing the flop. I guess you could value bet the river if you plan on folding to a c/r AI. You have $51 behind so folding to the c/r is actually impossible really as you should probably bet around $25 on the end.

I think this is one of those times you make a bet that looks like a donk bet so he'll call or shove. I make it $11-15 and call the shove.

Don't push or even reraise the pot. Anyone who has a hand and wants to go on has to raise on this board so pretty much ur asking to get priced out of your draw.
On riv it's pretty clear opp has the straight so just 2/3rd pot it and watch him go ugh!!!!! and call.
