the good old BTx-testsuites...still good for testing Leela imo
...not the only questionable testposition in this suite...an other one (beyond others) is No.4:
[d]5r1k/1P4pp/3P1p2/4p3/1P5P/3q2P1/Q2b2K1/B3R3 w - - 0 1
bm Qf7
...well thats probably correct but is it winning ?
i analysed this position long time ago and came to the conclusion that its just a draw !?
has this been discussed already somewhere ?
