[Heir_Aparent]

this hand happened a while ago so it may be lacking some of the necessary info I had available to me at the time. so it might be a silly hand to post given it depends a lot on how the game was being played but i'll give it a shot.

I was taking it to villain pretty good at this point. I called his all in on the river with 4th pair for a 1k pot. since then he has changed his style up significantly and gotten much more loose, aggro, and sloppy. nontheless hes still a thinking player, not great, but typically solid. shouldnt i be prepared to call this river if im calling the turn(unless its a spade)?

I ruled out two pair for the most part except mayyybe a4. I thought a flush was possible but he may easily play it way fast on the flop. he INSTA shoved river. At the time i had more flow/bet sizing and game dynamic info going on, so if theres nothing to be gained from analyzing this hand lemme know.
