Originally posted by morgskiYeah, I've seen many problems like this one where you have to figure out how to put black in zugswang... so the half hour you looked for a check is the half hour I gained knowing that wasn't the point. 🙂
Good job Tomtom, you posted 30 minutes after me, so beat me by at least 30. I was stuck for ages thinking the threat of Bb3+ meant the first move by white had to be check. 🙂
