It is more convenient to look at the analysis mode but you can still learn without other programs from asking tiger to play. Not >everyone can afford to buy many chess engines, and some of us like to use chess >engines to learn technique in chess. A small minority use engines to learn playing tablebases positions. Even if you use engines as a training tool there are more important things than tablebase. I think that tablebases are not relevant in 99% of the human-human games. Uri
