@FischerRandomChess cool games! second game reminds me of this composition by opper with passive sac theme:
lichess.org/m5e6v5Iw#0this type of mate is indeed a typical thing to watch out whenever your king starts right between two rook. I believe this mate is also called Eppault Mate. (Here is another game of Magnus Carlsen with that type of mate shared by Opper with me:
www.chessgames.com/perl/chessgame?gid=1272702) Not only the kings file is vulnerable, but the king is also vulnerable to smothered mates as the pawns in the rooks diag are not protected, e.g. 1.g3 Nc6 2.Nc3 Nb4 3. Nb3 (premove) and Nxc2#.
Another related game example:
for example in the game i was planning to simply 0-0 if white had played h5 due to hxg6 fxg6 Bf4 and now thanks to queen on b8, Qxf4 (or Rxf4) and mate next move:
I had also couple game where white had Rh1-Kg1-Rf1 starting position and with black started with Qc8-Ba8, then white allowed me to Bxg2 with the idea Kxg2 Qg4#. So it occurs now and then, its def something to watch out for :)
