I figured you were burning the top card, but I figured that the "which" card was just something we were going to have to get used to not knowing since online play allows for different things that RL play never would.
For example, one thing I pointed out to Spidey is that in RL, each person gets to know what the people before him bid before actually bidding themselves. This allows a bit of additional information about relative strengths of hand, which gives later bidders an advantage (yet one more reason why the deal rotates, to spread this out). For example, if I have a half-decent hand with 3 cards and the bids prior to mine add up to 5, I may not be so confident that my 8 of trump is going to take a trick. In fact, it might be a better assumption that I'll be able to ditch it somewhere.
At any rate, it really doesn't matter whether or not we know what the burned card is, as long as we all are playing by the same rules. Yeah, on any given hand, it might be more important for one person than any other, based on their cards, but the odds are still always the same for everyone.
