Player2 has 66% flop cbet, so he is checking most of his range on this board and dont want to give free cards to 2 players.
Player3 is tag but stationary, fold to cbet 3 of 10, 1 of 4 on turn, WTSD 38% W%SD33%.

I can think of goodd reasons to bet, c/c or c/r. I'm kinda lost cause I never really donk lol.

check raise/call on the turn looks bad vs this guy,he will check back often on this drawy board.
This is a clear turn donk bet imo after you have chosen to flop donk bet.
You only get into problems here if he raises your bet,which he probably wont do always even with the str8 .
Btw i wont classify someone as being TAG with AF:1.1.lol.
TAG means tight preflop,but aggressive postflop.

I dislike the donk on this kind of flop, any FD has "overcards" so will call your check/raise, and any JT, KJ, etc will just fold the flop, dunno why you say you don't want to give freecards, you hope for one of them to pair up

both replies make a lot of sense ty.
Agee, donking again is better than checking cause he will most likely call with the straight (and obv a lot of other hands)

Also when player2 bets he has a strong range that will call the raise, so more value on c/r. Also most of his air is still very far behind, given he prolly bets all his draw so if he checks behind no deal.

I ended up c/c calling a 7 into 10, and c/shoving 3o river (he bet/folded 15 into 24 with 20 left lol)
