Stupidly played KK, what to do on river

[ukpokerplayer]

2/4NL, 10 handed.

I raise to $17 in EP with black KK

One caller in LP, rest fold. No reads on this guy, he has been here for about 6 hands. We both have $400 atstart of hand)

Flop comes 2h2s3c (Pot about $40)

I bet $32, he calls. (pot about $100)

Turn is Jh, I bet $70 he calls.

River 5c. I check, he instantly moves all in (about $280)

What to do?

[Heimdal]

I think you played it well (as how I would have played it). Call river

[scdavis0]

nasty

i'd probably try to use some kind of timing tell or PT stats

[ahnuld]

I check turn to induce bluff. Given how you played it, I call river

[tdomeski]

timing tell > PT stats
