Hmm yeah I guess you are right.
Blocking 77,J7,86,63s and having robust equity against his calling range was just too enticing, but the possibility of getting 3bet and having to fold probably tips the balance. Still not 100% sure. Thanks for the replies. Bonus question: if we have a c/r bluff here what would that be?
If I had to choose between this and barreling I would choose this though, I don't see why we would want to make him fold all the 5x and call with most of his better stuff.
x/c would be my default option when I don't have a bout of fancy play syndrome.
