Here are a couple of quirks in the way Fizbo 1.9 writes PVs that are disturbing me.

1. In its comments to a game vs Andscacs 0.92, specifically, in the PVs for its moves 45 and 46, Fizbo wrote illegal moves (45. d7 c2 46. d8Q cxd1Q+ h5+ Qf4+), and as far as I remember, it was writing those moves in PVs during the game too (in the Arena GUI). I hope it's only a display bug and Fizbo did check those pseudolegal moves for legality during its search.

2. In the analysis of the final position of the following line,

[Event "Computer chess game"]
[Site "?"]
[Date "2017.09.20"]
[Round "?"]
[White "tony"]
[Black "tony"]
[Result "*"]
[BlackElo "2400"]
[ECO "A80"]
[Opening "Dutch"]
[Time "01:30:47"]
[WhiteElo "3222"]
[TimeControl "30/120:40/120:60"]
[Termination "unterminated"]
[PlyCount "30"]
[WhiteType "program"]
[BlackType "human"]

1. d4 f5 2. d5 Nf6 3. Nf3 c6 4. c4 e6 5. dxe6 Bb4+ 6. Bd2 Bxd2+ 7. Qxd2 Ne4
8. Qd4 O-O 9. Nc3 c5 10. Qd3 Nxc3 11. exd7 Ne4 12. dxc8=Q Qxc8 13. g3 Rd8
14. Qc2 Nc6 15. Bg2 Qe6 *

Fizbo gives the 'normal' move 16. O-O in the 'final' PVs of each search iteration but the nonsensical 16. Qxe4 with an advantage for White in 'intermediate' PVs, not just the first few ones, but in every other variation throughout the search Shocked

Code:
FEN: r2r2k1/pp4pp/2n1q3/2p2p2/2P1n3/5NP1/PPQ1PPBP/R3K2R w KQ - 5 16

Again, I hope it's just a display artifact, not a search bug.
