And Carlsen misses a decisive counter-trap - game 4 !!

Game 4 - Carlsen takes the Berlin route and trades for safety in move 35.

Vishy plays 35 Ne4 nviting Carlsen to gobble up the pawn on g4 and Carlsen obliged...the experts exclaimed as to why the need for speed.

because after 35...Rxg4+ 36. Kf2, everybody wanted black to play Ne5 or Rd8 to counter 37. Nd6+

The idea of 36...Ne5 is to support the rook on g4 and 36...Rd8 is to keep White from playing Nd6+

Here is the position following 36...Rd8.

37. Nc5+ bxc5 38. Rxg4 Ne5 and black threatens to take the rook back with Nxg4+

if 39. Rg3? Bxb5 (takes the piece back and the exchange fork remains!)

                                                       

but Carlsen obliged Anand's favor in game 3 and let go with a simple Rf4+ and rook back to Rf8 !!

Of course, it might be argued that Anand may not have played Nd6+ or Nc5+ but a World Champion does not sacrifice a pawn just like that and go two pawns down and a World no. 1 is clearly not in his elements if he cannot follow a simple unwritten practice in Chess - capture an open rank with rook and the more important, activate a passive piece and bring it in into play!

So that the above is not seen as a criticism of two greats of the game, I must note here that it is an observation of how two Grandmasters approach a likely-long championship, with both seizing on the first opportunity to shun complex, potentially explosive combinations to positional play.

Incidentally, this means that both are relying on positional play, which is human and cannot be analysed as well with the help of computer software...got it? :)
