I have made experiments using chessV to play Enep (the online available variant I think is still bugged). The extra pawn side has played white, the enhanced knight side has played black in the usual setup. Time control was 30secs/move. The results are:
white extra pawn wins 50
black enhanced knight wins 35
draws 15
That means a 59% ratio win for white. According to HG Muller's rule of thumb the knight enhancement should worth 0.5 pawns. According to HG Muller with Fairy Max pawn odds give 68%. In the enep experiment, assuming linearity and same level of play for fairymax and ChessV, we get half a pawn for the 2 enhanced knights, 0.25 pawns per knight. When seeing that my first instinct was to cast aside HG's rule of thumb. Second thinking though I posed the extra half point not on the weak knightwa but on better center control for the extra pawn side. Could that worth half a pawn?
Any thoughts on this HG?
What about you Greg?
Now I'm in the process of making the same experiment with colors reversed.
