1/2 nlhe - flop 2 pair then a turn for the worse...
 

Playing the 1/2 NLHE at MGM on my first trip to Vegas last week. Had a good week in general but still this hand haunts me a little.

On the day was running well on previous table but moved to sit with friends. Have about $300 in front of me. I think i have laggy image at new table, raising and betting with a wide range of hands (but having to release a lot of marginal hands). Still, I feel i can use this image to land a big pot when this hand comes up.

I hold 67 and 3 players limp to me in CO so i limp. Button folds and flop gets seen unraised (pot is $12).

It comes 2 6 7, rainbow. Villain is BB and bets out 10. (only read i have is seeing Villain lose big pot with TPTK vs Set about 15 mins earlier).

It folds to me and i raise to 30. All fold to Villain who calls.

River comes an 8 (also making two spades). Villain checks and i bet $60. Villain instantly moves all in (and covers me).

My action? Comments on all streets welcome...
