Instructive chess positions (and famous games/studies containing these) that engines do not understand well Basically, I would like to ask people to share their knowledge on famous and/or particularly instructive examples of chess positions, which chess engines do not understand well (i.e. do not evaluate correctly).

A good example of the kind of positions I am interested in is the Vančura Position-Wiki (cf. also Vančura Position-Chessbase), which occurred very recently (at the Sinquefield Cup 2014) in the game Carlsen-Aronian. Although the engine was saying white is completely winning, the game was a theoretical draw after black's 48th move.

Thanks in advance!

P.S. I should stress that I am looking for realistic examples, i.e. those which are likely to happen in a real game. Positions of the following type,

[fen "4k3/4p3/3pPp2/2pP1Pp1/1pP3Pp/pP1K3P/P2RRR2/8 w - - 0 1"]


and similar artificial positions is not the kind of thing I am looking for.

I should also say that endgame tablebase examples are OK. The only requirement is that engines (run on an average computer) are not able to evaluate the position correctly after given, say, 10-15 minutes time to "think".
The following two links seem to be exactly what you are looking for (many such positions in each one of them).

A cute study, which engines are unable to solve last I checked (white to move and win):

6r1/p1p1p1pP/P1PpP1P1/8/2P1B3/2K3pp/3P2rq/R5bk w - - 1 0
