How to Study Wesley So's Games
1. Separate early So from peak So
Early games often show direct attacks and tactical ambition. Peak So adds more control, fewer weaknesses, and cleaner conversion.
2. Watch the risk profile
Ask whether So is allowing counterplay or simply asking the opponent to solve one small problem after another.
3. Track the trades
So is often very strong when the position simplifies. Pause before queen trades and rook endings to ask what remains.
4. Build repeatable player lessons
Do not copy every move. Extract habits: safer king position, patient piece improvement, cleaner trades, and conversion without unnecessary counterplay.
