27: Stop and Go This or Just Fold?

[Ortho]

Button seems reasonable. The only hand I played against him I raised to 3x from the button, declined to c-bet the rag flop and folded to a turn bet about 10 hands ago. I feel that this may give me some additional fold equity. I'm genuinely unsure whether I should stop and go this or just fold.
