50nl- barrel this brd? or give up otf?

[Micro2Macro]

if you want to barrel the fish because you think his range will be weak think of two things:

1) BOARD TEXTURE
2) EQUITY

here you have 8 high and I wouldn't even count your backdoor crap straight draw on a two tone board as good enough equity. barreling off on T64 would probably work much better for your expectation.
