I'm new to the table, however I saw villian play a draw with a decent line. I'm assuming he's not a standard NL5 donk.

After he called my 3bet, but didn't 4bet. I put him on a middle to low pocket pair or two royals. ie 22-QQ or AT+. I dont think narrowing it down any futher would be accurate.

Is the turn check good or am I losing value to another overpair?

Is the river call good, following my turn check?

I'd welcome any comments. Give an NL5 thread some love.
