Hi guys. I know it states there are no questions that are stupid on here however. I don't understand the plays I make sometimes that don't work for me. For instance on one table I am playing tight and I get a decent hand AJo whilst in HJ position. I raise 3bb everyone folds aside big blind who calls.

The flop comes 3d 7c Js and I feel I still have the lead so I bet out in front again with a half the pot bet. BB calls again.

Out comes a 9d on the turn so I check and BB checks through.

River comes Ks and I raise and BB calls.

To my delight he only had pocket 10's but u don't understand what value he's getting with an overcard on the board as well as me raising pre flop. I am not complaining as I got value myself but I don't understand online poker why do people insist on calling through to the river (0.01/0.02 stakes BTW)

This is the first time I have got away with I usually get riveted and I was surprised that the BB didnt have a K and rivered me.

Sorry if there is any bad poker grammar or etiquette used as I said I am quite new to this.

Criticisms are welcome.

Thanks.
