I am VERY confused. The idea of introducing "!!!" for moves say completely outside the range of grandmasters grasp of the game seems interesting - but what on earth has this to do with the "baby" problems you suggest. Even a mediocre chess player see that Re8 is the easiest win in the first position. Black is dead lost and white can actually win by other moves than Re8. In the second position Rf6+ is almost trivial and it is hard to imagine any woodpusher who would not make that move. Even someone who got his/her first chess set this christmas should by now have no problems in finding Rf6+. And clearly Kh2 also wins... The third problem is a clear draw so I do not understand you suggestion about something might be hidden down the line. Could you be more specific? Soren Riis
