last night i got insta min raised twice:

1- he called my pfr, c/r insta on T T x drawy-flop, I 3bet he went all in. he had QQ, I had KT.
2- same deal except A A x flop and different villain. he showed 55, I had AT.

point is I think I'm gonna try and get reads before 3bet bluffing or anything from now on...
