don't fold....

In general, this is a good line to take on boards where you want the the caller to catch something on the turn to pay you off.

On a board this drawy/high you do not need to at all... So there's not too much merit in playing anything but a bluff like that.
Plus if you have a draw, c/c the turn reveals a lot about your hand (gooddraw/pair)...

Basically this is a fastplay flop, so a c/c, then donk to me on a 3 spade turn is suspicious not as a monster..

I think youll see a gutshot + spade draw here a very high % of the time.

Fold river if board sraightens or spades..

I think the only hand id play like this is J4s and a gutshot with a spade draw.
