yeah, that is a nasty spot. either V1 or V2 could have 68, probably not 8J.
the fact that V1 is check raising you here OOP is kind of wierd since most of the hands that he could be doing this with are drawing hands, not value hands.
I would muck it based off the strength of V2. V2 is going to show up with QJ, 68, 9T, 99, and TT almost all the time. V1's check raise is pretty odd since he is committed to donking almost all of the turns versus whatever you are holding.
Too bad V2 is in there, because you have V1 right where you want him.
note*
220 BB is not super deep. It is not even deep. 300 BB is deep. 600+ BB is super deep.
Assuming V2 is not in the hand and V1 is making a move on you with some kind of drawing hand, like QJ or 89. After you call the 175, the pot is 450 on the turn and V1 has 920 left. Let's say the turn is a brick, 2
, and V1 fires out 300 on the turn. You call. The pot is 1050 and he has about 600 left. River is a brick, 3
, and V1 shoves for his last 600, and you maybe call or fold, it really doesn't matter. The point is that being 220 BB deep barely gives V1 room to make 3 moves on the pot. One on each street. Deep stack poker implies that you are deep enough to 4 or 5 moves against your opponent to win a pot. You can see that 220 BB is only deep enough to make average size bets on each street and there is not even enough room for you to make a rebluff on any of the streets without V1 either snap calling allin or folding.
