Playing bad like me has not only disadvantages: after the game against @pereu4ivatel I wanted to know how I could have won in an overwhelming position and decided to check the situation before I made a really terrible mistake (I had 'forgotten' the black bishop at b2 and played 24. Nf6+??). With a clear mind without time pressure rather quickly I found a really nice and strong move - do you see it it, too?
It’s d6!
No clue at first glance. Waiting what others come up with.
OK, I will check tomorrow if there is any answer before I post the correct move.
