Hi,

MP and SB are unknowns, BB is a weak/tight reg.

Flop: his donk looks pretty strong, I put him on: sets, strong draws (nut FD, combo draws like OESD + pair,..), maybe few combos of 9x - JJ if hes fishy.

I think calling >> raising, expecially w/ 2 players yet to act behind me.

Turn: one of the worst cards in the deck for me so I am folding, despite getting ~18% pot odds. I might be drawing dead some of the time.

Thoughts ? Thanks
