So in short this mtt is freeroll with ticket you get by losing enough on cash games previous week (not hottest plo run that week). Around 140 left and top 10 get 400€ so pure cEV with pretty shallow stack.SB has seemed solid and has been active player.
So SB open (dont remember size, probably bit over minraise) and I call. SB check flop so went for half pot and he called. This turn donk bet is pretty weird imo. Could be some A2, 45, 55 from made hands. Maybe some sort of better hand from flop as slowplay. But turn doesnt really chance board much so I would expect villain to mostly go for check on turn. Personally would not really have any donk bet range on that turn after making x-c on flop.
Well I think its tough to fold top pair and no blocker to draws on turn. So went for call and called blank Th river.
