Hero has been running 21/16/2 and villain 32/2/1 over 53 hands. On flop/turn I was betting for value vs this villain (who had been calling down light) as well as trying to protect against draws. How would you play the river? Would you check behind? Push to the min-checkraise? Call or Fold and why? Comments on all streets is appreciated. Thanks guys...
