BB+P vs RN

[Nordlandia]

Can black draw with optimal play in this imbalance that arise from the game Berthelot vs Glenn Flear [1988]
[d]5k2/ppp2ppp/1b6/8/6b1/2P5/PP4PP/RN2K3 w - - 0 20

"An unbalanced position has arisen straight out of the opening, in which, with an open centre, Black has a pawn and the bishop pair for the exchange. Is it enough compensation?"

Glenn Flear wrote:
The defender probably has more chances of successfully defending with the pair of bish-
ops than "with other minor piece combinations. This seems to hold true even when the board
isn’t opened up for bishops. Indeed, there is a certain school of thought that claims that ’a
pair of bishops equals a rook and knight in the ending’. I’m not sure that this assertion can be
proven, but I decided to look at it from a statistical point of view.

From a sample of 68 high-level games in the NQE of rook and knight vs two bishops (this
time with players rated 2550 and above), there were 30 wins for the rook< and knight duo, 20
for the bishop pair, and 18 draws.

The number of wins achieved by the bishops seems quite high, which may reflect the
double-edged nature of this imbalance, but the overall percentage is a respectable 57% to
43%. We can interpret this as such: a pair of bishops shouldn't be underestimated, but the
rook and knight are still superior.

Indeed, two bishops and a pawn are often sufficient compensation for a rook and knight.

When the side down the Exchange has the bishop pair, my data shows he needs only 1.15 pawns to make things even.

Can Komodo 9.3 manage to draw this endgame against latest stockfish dev?

[Dann Corbit]

In the actual game that was played the game was easily won for white if he had played Kf3 instead of a5 at move 38.

LENOVO-PC-2, Rapid 10m+10s 2015

55% score for K9.3.

Komodo is stringer and it is only 20 games. What is this supposed to tell us?

[Dann Corbit]

With this game count and K being stronger, there is no conclusion of any sort that can be drawn from this.

[Nordlandia]

With this game count and K being stronger, there is no conclusion of any sort that can be drawn from this.

Of course there can be drawn some conclusions.

Since black never won a single game, black was always worse.

So the conclusion is that the RN side is the favourite side Ceteris Paribus, (hinted by Gleen Flear).

So the conclusion is that the RN side is the favourite side Ceteris Paribus, (hinted by Gleen Flear).

I think the conclusion may be valid, and the test does offer some evidence, but I think a clear test would be like this:
1. Use the same engine for both sides
2. Run 2000 games at least.

Then we will probably know the answer (unless it is too close to decide)
