strangely played hand vs daut44

[ipokeder]

my stats on him (most from a long time ago) are 18.6/14.0/2.34 over 7700 hands. i used to talk with him a lot about poker but not so much anymore so i'm not sure how good he is, but fromw hat i've seen of him at the tables he's really easy to play against and basically never gets out of line, though he is fairly capable of handreading.

given that, i was absolutely sure that he had a big hand on the turn. MBOE is 26.4/11.3/2.54 and seems like a very uninteresting type of straightforward player. i didn't want to raise the flop because i figured if i got it all in here i'd be behind like always, either to a dominating draw or twopair+, and if somebody had an underflush draw i had the chance of stacking them. bad rationale?
