I have seen villian on a couple of my tables before and he seems like a solid player so i dont know why he is limping here espescially with his stack size. seemed like a strong hand to me so i figured id check it and look at the flop, whereas i would usually push against an unknown. what do you think id usually see here coming from a solid player?
