"Oh, it's just me and you? I check.."

[bad beetz]

What's with this at Low limit games? friends, or even people who don't know each other, will check hands all the way through heads up. If this is not the case they will often check the river knowing they have the best hand. When I push a small +EV value bet on the river, sometimes people look at me like I'm an jerk.

I play quietly, and would never insult another player. I try not to check-raise the river heads up at LL like Sklansky and Malmuth suggest, but I refuse to not bet at all and to miss a bet on the river just to be cordial, and then I feel like I get chastised for it. I understand that some of them are just there to have fun, and that means playing lots of hands, and not losing too much on each hand. But, that's not why I'm there.

anybody ever miss a bet on purpose to "be nice?"
