I've only been here a few hands, and this is the first hand i've raised, so i don't really know who the calling stations are yet, and i certainly havn't seen him 3 bet before since i only have like 12 hands on him, i have no idea. The reason i sat at this table was the average pot was $4.

I honestly don't think the river could have helped his hand, but i don't know where i stand.

What's the river move? Effective stacks are $6.80 here.
