UH! What now?

[mongidig]

Lets change things around a little bit.

Scenario 1) The flop comes Ac7d3d.....would you consider folding now or is the pot still too big to fold?

Scenario 2) The flop is slightly different(Ad8d3c) but this time you hold 7d6d......Now what?

Scenario 3) The flop once again is the same as actual hand...you decide to cap the flop and everybody calls. The turn is Ad7d3c3d...It is checked to UTG who bets, tight passive calls...What do you do?
