Yes I know pf is not standard. I lke to raise smaller with speculative hands once in a while to try to build family pots - if I whiff the flop I just c/f - HU I can CB and take hte pot down often - also I'm surprised how often the table folds around to small opening raises - and when yahtzee strikes and I flop a monstah there is more chance with more villains hopefull seeing the flop that someone somewhere flops something goot enough that I can stack.

Villain is total unknown just sat at this table and I'm playing from laptop in a hotel and don't have access to ye db...

I hate to give up on this flop with my OESD +bdfd.

raise and call a push?

call an re-eval?

just fold??
