On river think a lot, and decided that there could be set weaker or 2 pairs or flash draw. Don't see too much streets, only J9, JT or AJ,KJ,QJ hearts. But JT most preffered to raise flop because of possible flash draw. Comment pls.
Don't give results in your post, especially on a hand like this.
I'd say someone value betting into a 4-straight co-ordinated board on two streets is generally holding at least a J here. But it's hard to say without reads.
2 callers pre, flop called, turn gets bet and 1/2 P on river wants a call from anything. this is a hand dynamic that makes poker what it is, a thinking game. haven't clicked spoiler and won't. like krim said don't post results, you don't need instant gratification!
