why did you check the turn? there is a reasonable answer to this and a likely misapplied answer to this. i'll give a hint about the misapplied answer, it rhymes with snot patrol.

since you checked the turn and then lead the river, don't you expect to get popped by a fairly wide range by this guy? i would. your turn check indicates weakness and a guy like this is all over it. he's trying to put you to a tough decision, but in my mind you really don't have one.

you should have decided much earlier in the hand what you were going to do. before you made the flop bet. assuming you flop an overpair, with an SPR of 4.5 you are usually committed against this guy. that means going to the felt and feeling okay about it. if he got lucky and flopped/turned/rivered a powerful hand don't sweat it. make the right plays and you'll get paid. instacall that river, IMO. you likely induced a bluff raise; good job.

against this type of opponent, alot of times we can extract the most by letting them maintain the initiative, btw. for that reason i'm curious as to thoughts on checking the flop. seems like he would bet with a much wider range than he woudl call with, but i could be wrong.
