Know when to hold them

Despite the recurring hoo hah about draws in chess, there is a certain appeal to games that end in "exciting" draws. By "exciting" I mean positions where won side is materially losing or facing imminent death, except for that one drawing resource they have.
Of course for the experienced professional a draw is a draw, no matter how its achieved, and what may be flashy to the spectators is simply a means to an end for the players.
Round 2 of the London Chess Classic saw all the games drawn, but at least in the Carlsen v Caruana game, the rather dry play out of the opening was somewhat redeemed by the last few moves.
