Another example then, Internet bullet game. I'll comment what's going on below, main point being my LACK of PLAYING STRENGTH.
[White "***"]

1. e4 {1} 1... c5 {1} 2. Nf3 {1} 2... d6 {0} 3. Bb5+ {1} 3... Bd7 {7} 4. Bxd7+ {1} 4... Qxd7 {0} 5. c4 {1} 5... g6 {1} 6. Nc3 {0} 6... Bg7 {0} 7. d4 {1} 7... cxd4 {1} 8. Nxd4 {0} 8... e5 {0} 9. Ndb5 {3} 9... Bf8 {3} 10. Nd5 {1} 10... Nf6 {2} 11. Nbc7+ {resigns (Lag: Av=0.28s, max=0.8s) 1} 1-0
1. e4 ... thank god it's not 1. d4, as I would have had to put back the c pawn back to c7, relocate the cursor to g8, pick up that piece, etc., it's all quite bothersome
1. ... c5 yippee I know this, it's called the Sicilian
2. Nf3 ... thank god it's not something like 2. d4, 2. c3 or 2. Nc3, en garde!
2. ... d6 yippee I still know this
3. Bb5+ what? wut?
3. ... Bd7 confusion (you see I took 7 seconds, most of it probably to adjust the mouse from g8, pick up the right piece, move it to the right square, that sort of stuff 😛)
4. Bxd7+ check
4. ... Qxd7 yay I managed to premove this
5. c4 wut?
5. ... g6 I don't know this so I'll just make the standard move, had that pawn under my mouse cursor already anyway
6. Nc3 premoved that one
6. ... Bg7 wow I premoved that too, pretty risky as 6. Ne5 could've been played as well
7. d4 "oooh, that's not a problem"
7. ... cxd4 ... as I'll just take it and be safe
8. Nxd4
8. ... e5 while thinking this, I bang out another incautious premove
9. Nb5 whoopsee how am I going to cover that pawn... hmm...
9. ... Bf8 I must be a genius, got it all covered
10. Nd5 whoopsee I guess not
10. ... Nf6 whoopsee where is that resign button
11. Nbc7+ Heinzkat resigns, sends applause and logs out.
Mind you this was at the end of an hours-long maniacal clicking session, that must be part of the severe incautiousness too. I signed out after this game 😛 But the underlying concept is that I do not have the playing strength of someone rated 200 points higher, because I simply miss the ready knowledge on the intricacies of many openings, in this case 3. Bb5+, I would not even know under what name it is known.
