Why didn't he play 6. Be4#? The castle seems unnecessary.
did you see the bishop that can take the white bishop?
Mmmmf. I didn't.
Difficult but beautiful !
one of the best
Black can't play Kg2, but he can play Bxe4
Nice. Very Interesting. :]
surprised about the castling of white king as part of the moves...
missed the 6th move.
6.Be4# looks quicker than 6.0-0 and 7.Nh2#
Nice!!!I loving it!!!
Not equal. After 4.f4+ black would play 4... Kxf4.
It's totally useless since there is a bishop on b7. It is not checkmate.
I think white`s 1st move knight to g5 could also be potential and lead to mate pretty quickly?
Love it !
I failed the puzzle, but find my solution (and Lasker's!) of Be2+ Kg2 Rh2+ Kg1 O-O-O# to much more aesthetically pleasing!
