There's 350 in the pot prior to seat 3's bet on 6th, since it's been checked down after the 3rd street calls of the bring-in. I've got 11 outs to an 8 low, and 4 more outs to a flush. If seat 2 calls, I'm probably getting proper actual odds to call, although seat 3 could be on a draw to a 7-low and also could be on a spade draw, so I'm not a lock to win one side or the other even if I hit one of my outs. If seat 2 folds and I hit the diamond, the implied odds are very good (if the flush holds up), because an additional 800 will go in the pot on 7th, while if I just hit the low, I'm fairly certain that seat 3, based on his play in previous hands, will call even if he's just sitting with QQ, and we split the pot.

So, is it correct to call or to fold?
