Stats mean very little. One could have a lower "losing percentage" by taking fewer risks, being highly proficient in endgames, or by playing a weaker average opponent.
The real test would be the win-draw-loss percentage in games against players within 200 points of their rating AFTER being down a pawn (or the positional equivalent of -1.00 by Houdini or another strong engine). That would illustrate defensive results.
My own list would include the most fearsome counterattackers, Lasker, Rubinstein, Alekhine, Keres, Korchnoi, Karpov, Kasparov, Ivanchuk, and Anand.
"Best defence is attack." <-- Who said that..?
Better solution for black are:15.Ba6+ Ka416.Nxc6 and so on, like simulator below:
"Best defence is attack."
The best defence is a good offense? Perhaps Sun Tzu, Machiavelli, or Carl Von Clausewitz.
