Alright now for the twist.

So far we've gone forward with the assumption our TAgg feels he's playing for stacks if he continues with his hand. However, many weaker and some not so weak players will often just call the raise, check/fold the turn, but attack any weakness. Or just check/call it all the way. Really weak players will often call the flop bet (in for a penny, in for a pound) then get second thoughts once the turn hits.

Against a call, how often should be follow through on the turn?

Consider that it's quite possible Rippy makes a lot of money following through here.
