The effect of using the Nalimov-Tablebases seems to be not quite clear. Those tablebases are not at all based on evaluation means certainty or uncertainty. The tablebases are not an engine evaluating or assessing any position or recommending any move. They are a gigantic database including all (and I mean all!) 5 pieces endings. The 6-pieces tablebases don't include all 6 pieces for the moment but nearly.
To give you an example - and I have to add that using the Nalimov-Tablebases without engines doesn't make sense at all. So if you allow the use of the Tablebases you have to allow the use of engines too.
The example to make it quite clear: When any engine (and I assume that most engines have access to the Tablebases and can cooperate)comes within the reach of the tablebases it's only a question of the power of your PC when he finds - within the split of a second sometimes - the position in the tablebases, then however he gives you the result:
a) Mate within ...moves (meaning you'll lose or you win)
b) Draw
There's no other result and it has nothing to do with an evaluation that's the result of the game!
That means if both players use the Tablebases they can stop playing as the result is clear.

The tablebases have to be inegrated so that the engine can access them. And if you set up a position like the one you mentioned the engine will immediately access the TB and tell you within a split of a second: mate in 25 moves. BTW for that type of ending you'd need no TB at all as the engines normally can handle that endgame without.
