this is a video on chess or something and this is a position from hikaru nakamura against magnus carlsen. In this position, gothamchess suggested we sacrifice (sac) the ROOK in order to solve this IMPOSSIBLE and DIFFICULT puzzle which is EASY and for BEGINNERS INTERMEDIATE and EXPERIENCED PLAYERS 100 elo+ 2000 elo+ 4500 elo+ puzzle. Paul morphy and bobby fischer watched this game and they appreciated the ROOK sacrifice and something like that. This position is very similar to a gothamchess funny moments because we disrepect the opponent. This game started out from an italian opening and hikarus kings indian defence. This puzzle was solved by STOCKFISH in 1605. This is a mate in 2 but we made it into a mate in 4 and a mate in 3 and a mate in 1 and a mate in 5 or a mate in 6. This was played on chess.com and not on lichess.org or chess24.com because fabiano caruana doesnt like those other sites as well as anish giri.
