To play the devil's advocate, here's a replayer where the "reverse next" strategy failed me. My partner, the dealer, turned down the ace of spades. I have the king and nine of hearts, and decide to call hearts, even though my hand seems very weak. Well, it turns out that my hand really was weak compared to the cards in third chair's hand. This is one of those cases that I was worried about when I first heard about the reverse next strategy - what if I call trump in a weak suit, and my left-hand opponent is strong in that suit?
Well, think about it this way. If you look closely at my left-hand opponent's cards, you'll see that the bot might very well have gone alone with those cards - and a loner would have been successful. So you could say that we actually prevented a loner by calling - we only lost 1 point, whereas we might have been behind by 4 points if I hadn't called hearts as trump. This example shows how reverse next might work in your favor, even when it seems like it failed, at first glance. I've posted a screenshot of the replayer, below, so you can see how all our hands looked.
