25. Bxg7+ and you have Rook for free.
When you underestimate your opponent
it happens many times. One match can be lost by anyone, that's why usually are played 24 games to find out the real champion of the world.
Not to demotivate you, you played very intelligent, but this things happens
@Strep, noticed that when analyzing myself. Annoying mistake.
I understand that, just happy I got a win against a stronger player =)
I am a weak chess player that plays once in a while to kill time. I challenged a 1400+ player just for the heck of it (I know most of you don't find 1400+ that impressive, but I am 800+, so it's quite a great difference.) I'm happy he resigned, though, I'm not good with endgames, he would've got a stalemate for sure, I always mess up those.
