basically the question is ive found myself in this position alot, ive folded every hand up to this point and need to extract maximum value from this hand as its getting to "that point" in the game, especially still FR with these blinds
the whole table has been especially tight (hence why its still 8handed) except the 2 guys to my left who have been passing chips back and forth, obviously i dont want to let everyone in on the pot...

after this i waited for a few more hands down the line and busted out with 10's, what would have been the best course of action here to make the most of my only hand?
