XG has no idea about the value of an outfield prime, hence it makes the 6 point. The move BGBlitz suggests: 18/12 24/19 is not even among the first 32 moves XG lists!!!.

1. Rollout¹ 12/6 11/6 eq:+0,572

Player: 81,07% (G:8,91% B:0,30%)

Opponent: 18,93% (G:9,27% B:0,73%)

Confidence: ±0,027 (+0,545..+0,599) - [100,0%]

Duration: 58,9 seconds

2. Rollout¹ 24/19 18/12 eq:-0,051 (-0,623)

Player: 60,79% (G:6,93% B:0,24%)

Opponent: 39,21% (G:27,77% B:0,35%)

Confidence: ±0,056 (-0,106..+0,005) - [0,0%]

Making a 6-prime and getting a potential 2nd checker is valued by XG as an -0.623 mega-hyper-super-blunder?

BGBlitz chooses 24/19 18/12 even with 1-ply, having 16/11 18/12 as the 2nd move in the error range. A rollout of XG's choice and BGBlitz moves shows reasonable numbers. (Just a simple 3-ply rollout, nothing fancy)
