Olaf is a high lane pressure juggernaut aiming to force extended melee trades and deny Yasuo's scaling by landing repeated (Q) slows and using (R) to ignore crowd control.
Olaf must pressure Yasuo early to prevent him from using minion waves for mobility and avoid giving Yasuo passive scaling time.
Trading pattern
Start trades by landing (Q) slow and pick up the axe to keep Yasuo within melee range for extended fights.
Use (R) only when Yasuo cannot fully disengage to ignore his knockup follow-ups and crowd control.
Punish Yasuo immediately after he misses (W) or when his mobility is down to force favorable trades.
Danger windows
Yasuo is most dangerous when his (W) is up and minion waves allow him to dash freely with (E); avoid extended trades then.
After (R) ends, Olaf becomes vulnerable to Yasuo's knockups and follow-up damage; disengage or reset fights.
Low-health Olaf can still win extended fights but must respect Yasuo's burst potential if caught out of position.
Early game
Use level 1-2 to aggressively land (Q) and pick it up to maintain chase and pressure before Yasuo unlocks his (Q)+(E) combo at level 2.
Deny Yasuo access to minion waves for (E) dashes by controlling wave position and forcing him into awkward trades.
Prepare to use (W) shield and (E) true damage to sustain and punish Yasuo's early skirmishes.
Power spikes
At level 6, use (R) to ignore Yasuo's knockup and ultimate follow-up, committing to all-ins only when you can keep hitting him.
First fighter item spike boosts your damage and durability; pressure side lanes and punish Yasuo's missed disengages.
Respect Yasuo's level 2 spike when he gains (Q)+(E) combo for mobility and trades; avoid giving him clean engages.
Win conditions
Snowball early by landing repeated (Q) slows, forcing long trades where your sustain and true damage outvalue Yasuo.
Use (R) to negate Yasuo's crowd control and commit to all-ins when Yasuo's mobility or (W) is down.
Pressure side lanes to deny Yasuo safe wave access, limiting his mobility and forcing him into unfavorable skirmishes.
