There's very a small chance you're ahead and a small chance you'll hit a queen.

If you're ahead of both opponents and neither bluff on the river 3% of the time then you're giving up you're share of ~.42-.45 BB

When you're behind you'll average less than 2 full outs.
1.9 outs / 46 * 18BB expected pot = .74BB with implied odds.

Combined Equity:
.74+.42=1.16
So if you think you'll catch a bluff or draw that didn't get there 3/100 times then you can peel profitably.
