Strengths
Start with the part of the report that should feel good: these are the pieces of your game already giving you something real to stand on.
Good news first
You are not starting from zero here. Tactical Eye is also helping keep the floor of your game higher.
Current edge
You are reaching enough familiar structures to avoid starting every game from scratch.
Also helping
You are spotting enough forcing ideas to create chances instead of only reacting.
Profile
A quick human read on where the next training gain should come from, without losing sight of what is already working.
Coach's note
You already have a solid foundation, led by Opening Prep. The next jump should come from Endgames, because that is the main thing pulling the rest of the profile down. Fix that one deliberately and the rest of your game should feel steadier without losing confidence.

“To take is a mistake.”
- GM Igor Smirnov
“When you have the advantage, don't trade — make your opponent suffer.”
- GM Garry Kasparov
“Loose pieces drop off. Always check if your pieces are defended before moving.”
- GM Dan Heisman
“A piece that is not actively placed is a wasted piece. Every move must serve a purpose.”
- GM Siegbert Tarrasch
“The player who controls the center controls the game.”
- GM Wilhelm Steinitz
“The king is a fighting piece. Use it! But never leave it exposed in the middlegame.”
- GM Wilhelm Steinitz
“The punishment for grabbing pawns is usually a lost tempo, and tempi are worth more than pawns.”
- GM Garry Kasparov
“Every move must have a purpose. If you can't explain why you played it, you shouldn't have.”
- GM Savielly Tartakower
“Do not hurry. The pawn structure is everything — it determines the entire game.”
- GM Philidor
“Develop your pieces to good squares, castle early, and connect your rooks.”
- GM José Raúl Capablanca
“Recapturing towards the center is almost always correct.”
- GM Siegbert Tarrasch

These patterns connect how you spend time to which positional mistakes keep appearing. Fix the connection, not just the symptom.
Time x Positional
One clear pattern stood out: 1 of your 191 rushed moves involved "wrong recaptures" (1%). Fix this one connection and both your clock and position quality should improve together.
Wrong Recaptures

1 of your 191 rushed moves involved "wrong recaptures" (1%). Averaging 0.1s per move, these cost ~0.0 pawns each.
Coach takeaway
Your main fix is speed discipline in specific positions. Run a quick blunder-check before commiting when you feel the urge to move fast. The pattern recognition will come with reps.
