Unknown player, flop and turn I think standard. On river opponent donkbet all in. Flush draw not complete, not many hands beat me (TT/99 or T9s should raise on flop or turn). I decide call here.

Well played. Pre-flop we see a 2,5x open, we 3b to 9bb, we can go even smaller to 8bb, but this is fine. Post-flop we get a relatively drawy board and just go over half pot which is fine, we don't want to go any smaller here though. Post-turn we want to try to get the money in. Betting $0,50 or $0,60 leaves about $1 - $1,10 for the river which is fine. On the river he jams. We block KJ pretty hard, he can have some club/club-bluffs, some flush-draws with a Q, that have top-pair now, some random bluffs. We call and win most of the time, this time we didn't.
You going to bet that river anyways, V shouldn't show up with J8s and KJ. This should have went in pre.
