V1's hand looks suspiciously like KK. It looks so much like KK, I would kiss the main pot goodbye.
The side pot makes a call worth it though. If we assume we're sacrificing another $225 to the main pot just to get to the side pot, we're putting in $1,425 to win $1,200.
My pokerstove isn't working right now, but I think our equity in the side pot has to make a call worth it. V2s range is obviously heavily weighted towards draws if we assume KK for V1. He's got 6 combos of 77. The rest is all draws. 5
6
and 77 are the only nightmare situations. If it's set over set over set, then it's a very serious cooler.
Plus, we do have at least one out for the main pot and there's a non-zero chance V1 has a hand other than KK. So, we've got at least a tiny amount of equity in the main pot.
