Your thoughts on this hand please

[DM99]

Just finished a SNG tournament where I ran pretty much card dead. This hand was the hand that crippled me. Any thoughts? Full Tilt Poker Game #8001945028: $2 + $0.25 Sit & Go (60854111), Table 1 - 25/50 - No Limit Hold'em - 13:12:19 ET - 2008/09/09 Seat 1: Valica (2,645) Seat 2: Kauz59 (2,435) Seat 3: diego4you (1,145) Seat 4: cestbonca (3,635) Seat 6: rai91 (1,025) Seat 8: HERO (955) Seat 9: Snuts Vinc (1,660) Valica posts the small blind of 25 Kauz59 posts the big blind of 50 The button is in seat #9 *** HOLE CARDS *** Dealt to HERO [Jd Ah] diego4you calls 50 cestbonca folds rai91 folds HERO raises to 200 Snuts Vinc has 15 seconds left to act Snuts Vinc folds Valica folds Kauz59 folds diego4you calls 150 *** FLOP *** [Jh 5d 7c] diego4you bets 50 HERO raises to 450 diego4you calls 400 *** TURN *** [Jh 5d 7c] [Qc] diego4you bets 495, and is all in HERO folds Uncalled bet of 495 returned to diego4you diego4you mucks diego4you wins the pot (1,375) *** SUMMARY *** Total pot 1,375 | Rake 0 Board: [Jh 5d 7c Qc] Seat 1: Valica (small blind) folded before the Flop Seat 2: Kauz59 (big blind) folded before the Flop Seat 3: diego4you collected (1,375), mucked Seat 4: cestbonca didn't bet (folded) Seat 6: rai91 didn't bet (folded) Seat 8: HERO folded on the Turn Seat 9: Snuts Vinc (button) didn't bet (folded) My first impression that it was a donk thinking he is tricky and slowplaying a monster like AA or KK. He called my big pre-flop raise, he min bet then called my big raise, then insta-shoved on the turn. Thoughts?

Re: Your thoughts on this hand please His min bet on the flop suggests to me he's drawing/looking for cheap cards - almost like a blocking bet. However calling the 400 and then betting all in (for 495) dont make much sense to me and it's difficult to put him on anything with too much confidence. There's only a straight draw on board though - so maybe he's a 5 or a 7 for bottom or middle pair :unsure Given the buy in, $2, and the betting sequence, and getting 3-1 on my money I think I probably call :unsure I read him more as weak than strong :unsure
