No real reads, although SB seemed to be a little bit laggy (~25VPIP ~22PFR) but the sample was very small.
I think the blind defence is ok, but perhaps I shouldve folded on the flop. I didn't tought there was too much value on the river in a raise but perhaps it wouldve been best and than fold to 3bet but not sure so thats why I post it here for comments.

I'd probly play it the same way, except I'd raise river. A lot of ppl will think you're FOS and call with as low as A high.

Just fold the flop... your hand sucks, the pot is small and you can't even get a rase in on your gin card.

I don't think I'd raise this river either since his range that raises PF and bets all 3 streets here is going to have you in pretty bad shape...

fold flop

None of your outs can give you a reall good hand you can raise with.
