Prioritize building Fury and controlling the wave to enable strong trades and side-lane pressure against Riven.
Manage lane pressure carefully to avoid giving Riven cooldown advantages that enable her burst combos.
This is a splitpush versus snowball matchup where Tryndamere must leverage scaling and death denial to outduel Riven in extended fights.
Trading pattern
Trade only when Fury is high and (W) stun or third (Q) knockup are on cooldown.
Use (E) to engage only if you can chase or reset the fight, and extend trades with (R) to survive burst.
Punish Riven's cooldowns by stepping forward immediately after she uses mobility or crowd control abilities.
Danger windows
Respect Riven's full combo when all cooldowns including (W) and third (Q) are available, especially with (R) active.
Avoid engaging without (R) or when your Fury is low, as Riven can punish these windows with her burst and crowd control.
Be cautious after using (E) forward, as you become vulnerable to kiting and crowd control follow-up.
Early game
Focus on stacking Fury safely before engaging, avoiding all-ins without (R) or full Fury.
Use (W) slow to reduce Riven's damage during short trades and punish her after she uses (Q) and (E).
Avoid using (E) aggressively when Riven's crowd control is up to prevent being stunned or knocked up.
Power spikes
At level 6, use (R) to force extended all-ins and convert low-health trades into kills or tower pressure; respect (R) by avoiding fights when she is fully stacked.
Leverage the two-item spike to increase splitpush threat and force enemies to respond, avoiding isolated fights without (R).
Respect Riven's level 6 (R) power spike and her ability to burst with full cooldowns; bait her cooldowns before committing.
Win conditions
Build Fury and pressure side lanes to force one-on-one duels where you can leverage (R) to survive and win extended fights.
Punish Riven whenever she wastes mobility or crowd control cooldowns by committing to trades with (E) and (R).
Reach your two-item spike and use splitpush pressure to draw enemy attention, enabling your team to capitalize elsewhere.
