I've 3 hands about Villain, He plays 100/0.

There's a lot of value OTF against 7x, 8x, FDs, OESDs, Ahigh floats, low pocket pairs.

Turn is interesting, because He had just 21 BB. Most of his flop range will fold to a turn bet, pocket pairs will check to get SD, 8x Kx will probably valuebet the river, and busted draws will probably shove the river... Can his river betsize be a difference between valuebet and bluff?

What should I do in this spot?
