A nice position from the game against nemorino:
[d]3Q4/pp4pk/5n1p/2b1q3/2BN1nb1/1P6/PB3PPP/R5K1 b - - 0 24
WaDuuttie had not enough time to find the winning move and after 24...Bb6 the game ended in a draw. Does your favorite engine find it ?

Nice event of the month , as usual , with 40 engines !
HGM's monthly tournament is very popular now!
And now a very good game played by Isa in the last round , a beautiful deadly king promenade , an horrible game by my poor engine !
Watching this , gave me the envy to stop the hobby !! :evil:
But the addiction is here ...
See you next month !
:wink:

It may be worth investigating why Isa played the suicidal 13..a5
It should see the problems even at low depths, though I've no idea how much time Isa spent on that move and how deep it searched.

24...b5 looks good here....
24... Bh3! 25. gxh3 Qg5 and white quickly gets himself into trouble.

The best white can do here is 25. Be6 throwing away two pieces for one to stop the attack.

WaDuuttie had not enough time to find the winning move and after 24...Bb6 the game ended in a draw. Does your favorite engine find it ?

Indeed is 24...Bh3 the best move and with a bit more time WaDuuttie would have found it (BTW he thinks 25.Bf1 is white's best defence up to iteration 24 and then switches to 25.gxh3):
