yes. there are different strategies for a TRUE no-hole-card situation. However, your post brings up a different issue and it seems fairly obvious that you are suffering from a severe case of ploppy logic.
There is NO DIFFERENCE betwen playing at 3rd base and playing anywhere else on the table (regardless of other rules such as no-hold-card). please do not let anyone tell you otherwise. The intelligent posters on this board and the TRUE advantage players understand this rather basic mathematical principle.
basically, you are trying to be an advantage player but you are still mixing in inaccurate information into your game.
you need to understand or at least acknowledge that 3rd base play is no different (at least in this respect)
the only way 3rd base play is different is that you will see more cards before you make a playing decision and thus may have a slightly truer count (particularly useful in face-down DD games for example). Another way it is different is that it can be easier to count a whole table at a glance without having to scan from side-to-side if you sit in the middle. counting at a glance can be helpful in remaining inconspicuous to the pit-critters.
But you are clearly referring to the popular fallacy of "taking the dealer's bust card" or some other such nonsense and obviously have no idea that it is nothing but a myth/lie.
