In all of the situations you are in the big blind, the cutoff opens, and the small blind cold calls. The small blind checks the flop and you're trapped with the cutoff to act. You can donk, check/raise, check/call, or check/fold. You can base whether you'd check/raise, check/fold, or check/call based on the small blinds action. However, the cutoff isn't guaranteed to bet on coordinated flops.

Some of you might notice I posted this in the high stakes limit forum. However, I wasn't getting very many mature replies so I thought maybe I'd get more thoughtful answers in this one.
