I was wondering how most of you would have played this hand.
I'm not sure how my river play was. I originally checked to
minimize my losses, but then when i thought about it, I had
about $50 left, so if he had me beat I think he would surely
bet that after i checked (since the pot was so large), but I
was definitely calling if he DID make the bet.

I like to play these suited connectors from fairly EP
and don't know if this is correct. Please comment on this hand,
and I encourage ANY criticism and feedback.

Thanks.
