I say fold 78 sooted is not strong, the chances of floping a flush is crazy and to flop a pair of 8's probably wouldn't do it. I say wait and try another hand because he is likely to call your all in with one over card too get rid of you so wait and see if you get a better hand and make him call you maybe he will fold and you steel a couple of chips. I like 10 8 better than 78 Either way it is 50/50 I've gone 72 off suit and pulled a two pair on river against pocket 10's so anything can happen!!!!!!
