7 years ago I think #416 resolves the initial issue. There will always be new ideas & room for further improvement but shallow mates seem not to pose a problem anymore:

opperwezen won one game after many losts. SF-Lvl8 and the server analyze overlooked this very nice 15...Rg1!! (found by SF after about 17 millions nodes) https://fr.lichess.org/1JQ3DgMe#29
-> this game is very interesting to tune search and eval : https://fr.lichess.org/TFT5J2FS#66 A lot of up and down after analyze. Especially this very strange 45...gxh5??? https://fr.lichess.org/TFT5J2FS#89
Note that opperwezen plays a lot of 25+2 and 10+2 these days : https://fr.lichess.org/@/opperwezen/search?perf=18&hasAi=1&aiLevelMin=8&sort.field=d&sort.order=desc
